Installation Precautions
Adherence to the following will aid in problem-free installation with long-term reliability:
WARNING - Several different sources of power can be
connected to the fire alarm control panel. Disconnect all
sources of power before servicing. Control unit and associ-
ated equipment may be damaged by removing and/or insert-
ing cards, modules, or interconnecting cables while the unit is
energized. Do not attempt to install, service, or operate this
unit until manuals are read and understood.
Like all solid state electronic devices, this system may
operate erratically or can be damaged when subjected to light-
ning induced transients. Although no system is completely
immune from lightning transients and interference, proper
grounding will reduce susceptibility. Overhead or outside aerial
wiring is not recommended, due to an increased susceptibility
to nearby lightning strikes. Consult with the Technical Ser-
vices Department if any problems are anticipated or encoun-
tered.
CAUTION - System Re-acceptance Test after Software
Changes: To ensure proper system operation, this product
must be tested in accordance with NFPA 72 after any pro-
gramming operation or change in site-specific software. Re-
acceptance testing is required after any change, addition or
deletion of system components, or after any modification,
repair or adjustment to system hardware or wiring. All compo-
nents, circuits, system operations, or software functions known
to be affected by a change must be 100% tested. In addition,
to ensure that other operations are not inadvertently affected,
at least 10% of initiating devices that are not directly affected
by the change, up to a maximum of 50 devices, must also be
tested and proper system operation verified.
Disconnect AC power and batteries prior to removing or
inserting circuit boards. Failure to do so can damage circuits.
Remove all electronic assemblies prior to any drilling, filing,
reaming, or punching of the enclosure. When possible, make
all cable entries from the sides or rear. Before making modifi-
cations, verify that they will not interfere with battery, trans-
former, or printed circuit board location.
Do not tighten screw terminals more than 9 in-lbs. Over-
tightening may damage threads, resulting in reduced terminal
contact pressure and difficulty with screw terminal removal.
This system contains static-sensitive components.
Always ground yourself with a proper wrist strap before han-
dling any circuits so that static charges are removed from the
body. Use static suppressive packaging to protect electronic
assemblies removed from the unit.
This system meets NFPA requirements for operation at 0-49º
C/32-120º F and at a relative humidity 93% ± 2% RH (non-
condensing) at 32°C ± 2°C (90°F ± 3°F). However, the useful
life of the system's standby batteries and the electronic com-
ponents may be adversely affected by extreme temperature
ranges and humidity. Therefore, it is recommended that this
system and its peripherals be installed in an environment with
a normal room temperature of 15-27º C/60-80º F.
Follow the instructions in the installation, operating, and pro-
gramming manuals. These instructions must be followed to
avoid damage to the control panel and associated equipment.
FACP operation and reliability depend upon proper installation.
Verify that wire sizes are adequate for all initiating and indi-
cating device loops. Most devices cannot tolerate more than a
10% I.R. drop from the specified device voltage.

Section 1: Product Description
The ACC-25/50 Series consists of the AUDIO•COMMAND•CENTER•25/50 (ACC-25/50), the
AUDIO•COMMAND•CENTER•25/50 Zone System (ACC-25/50ZS), and the AUDIO•COM-
MAND•CENTER•25/50 Zone System with Telephone (ACC-25/50ZST) which are single channel,
25 watt, 25 VRMS, emergency voice evacuation panels. The ACC-25/50 provides up to two
speaker circuits while the ACC-25/50ZS and ACC-25/50ZST support up to eight speaker circuits.
Each panel provides the ability to record five field programmable messages (up to 60 seconds total
message duration) with an integral microphone or from an external audio source. An integral
power supply with battery charger supplies operational power. An ACC-AAM25 audio amplifier is
provided standard with each base unit. An optional second ACC-AAM25 amplifier is also avail-
able for backup purposes or to provide an additional channel of 25 watts. Optional 70 VRMS con-
version modules are also available for installations where 70 VRMS speakers are to be installed or
already exist. An optional External Page Module (ACC-EPM) is available for interfacing to nonfire
paging systems. The modular design allows for ease-of-serviceability.
Automatic activation of the ACC-25/50 by an FACP is possible via the five Command Input Cir-
cuits (CMD). The ACC-25/50ZS and ACC-25/50ZST can be automatically activated by the CMD
inputs or via the ACS serial communications link from the MS-9600, MS-9200UDLS, MS-
9200UD, MS-9200(E) and MS-5210UD FACPs.
Two Command Input Circuits can be independently field programmed for activation by an FACP
Notification Appliance Circuit reverse polarity or by closure of a supervised normally open contact
and three Command Input Circuits activate on contact closure. CMD 1 and CMD 2 provide termi-
nals for NAC input and output to allow installation of the audio panel anywhere along the NAC cir-
cuit being used to activate it. Options via the Command Inputs allow one 60 second message, two
30 second messages, three 20 second messages, four 15 second messages or five 12 second mes-
sages.
The ACC-25/50ZS and ACC-25/50ZST include an ACC-ZPMK Zone Page Module with keypad
and an ACC-ZSM Zone Splitter Module. These modules provide up to eight speaker circuits that
may be manually or automatically activated.
The ACC-25/50ZST includes an ACC-FFT Fire Fighter Telephone Module with keypad which
provides indications of phone activation, remote page activation, remote microphone activation and
corresponding trouble conditions. Additionally, up to 24 telephone circuits can be annunciated at
the ACC-FFT by connecting addressable monitor modules to the optional FPJ-F or RPJ-F Remote
Page Jacks.
Significant technological enhancements set the ACC-25/50 Series apart from other voice panels.
These enhancements include full supervision in both active (alarm or music) and standby condi-
tions. Supervision is provided for:
amplifier outputs
field wiring (shorts and opens)
message generator
all tone generators
microphone
telephones (optional)
If the message generator fails, the system automatically reverts to the primary tone generator. If the
primary tone generator fails, one of three backups become enabled.
Power is fed independently to each amplifier so that a short circuit in one amplifier will not shut
down the other. Full output power of 25 watts per amplifier is generated while in a low battery con-
dition. Power is not diminished when the optional 70 VRMS transformer module is installed. Audio
is amplified utilizing modern integrated circuits as opposed to transformer technology. This pro-
vides for very low signal distortion for crystal clear audio.

1.4 Circuits
Input Circuits - CMD1, CMD2, CMD3, CMD4 & CMD5
•
Input circuits CMD1 and CMD2 are independently field programmable to accept Notification
Appliance Circuits or normally open contacts. (IMPORTANT! When CMD1 and CMD2 are
configured for reverse polarity, the NAC cannot be Coded). Terminals are provided to allow
feed-through of the NACs, allowing placement of the ACC-25/50 Series anywhere along a
Notification Appliance Circuit. A trouble on the ACC-25/50 Series will cause relay contacts at
the out terminals of CMD1 to open, causing an NAC circuit trouble at the FACP.
NOTE: The ACC-25/50 Series will not open the out terminals while in alarm or during AC loss if
independent trouble relay at TB1.
•
•
Programming CMD1 and/or CMD2 for activation on contact closure will allow activation of
the amplifiers on a normally open contact transfer to the closed condition. Contact wiring is
supervised for open conditions. A short will cause amplifier activation (contact closure).
Input circuits CMD3, CMD4 and CMD5 will only activate on contact closure which will allow
activation of the amplifiers on a normally open contact transfer to the closed condition.
Contact wiring is supervised for open conditions.
Audio Input Jacks
•
RCA Jack provides convenient connection to an audio source such as a tape player for
recording a new digital message. It may also be used for background music if approved by
local AHJ. Background music is prohibited during AC loss conditions to preserve battery
power.
•
PC Jack provides convenient connection to an audio source such as a personal computer for
recording a new digital message. The jack allows vertical plug-in of a standard mini-jack
cable. It may also be used for background music if approved by local AHJ. Background music
is prohibited during AC loss conditions to preserve battery power.

which is used to connect the FC-RM Remote Microphone to provide remote microphone
paging capabilities for the ACC-25/50 and ACC-25/50ZS (refer to Remote Microphone

Connector P5 provides a cable connection to the optional ACC-FFT Fire Fighter Telephone
Module connector J2 for the ACC-25/50ZST Zone System with Telephone. The FC-MIM
module function is incorporated into the ACC-FFT module eliminating the need for the FC-
MIM (refer to Section “ACC-FFT Fire Fighter Telephone Module (ACC-25/50ZST Only)” on
ACC-EPM External Page Module
•
Connector P13 provides a connection for the optional ACC-EPM External Page Module which
is used to connect external non-emergency page equipment. The electrically isolated signal
from the external equipment is not supervised by the ACC-25/50 Series panels. Alarm
condition and paging from the ACC-25/50 Series panels have priority and will override all

mounted in the cabinet.
Audio Amplifier Module [ACC-AAM25]
A single Audio Amplifier Module is installed in the ACC-25/50 Series. The amplifier provides 25
watts of power at 25 VRMS. An optional module, P/N: FC-XRM70, converts the 25 VRMS output to
70.7 VRMS. One fully supervised and power-limited speaker circuit is provided on the amplifier
module. The circuit can be wired for Style Y (Class B) or Style Z (Class A) operation.
LEDs are provided to indicate Amplifier Supervision (green indicates amplifier is functional) and
Circuit Trouble (yellow indicates field wiring fault or amplifier fault). The LEDs are only visible
with the panel door open.
Cabinet
The cabinet is red with an attractive navy blue front overlay. A clear window allows viewing of
status LEDs and location of microphone. The backbox measures 26.0" x 15.5" x 4.75" and pro-
vides space for two batteries (up to 18 Amp Hours). The ACC-25/50ZS and ACC-25/50ZST cabi-
nets provide a clear window to view the ACC-ZPMK module which is mounted in the center left
portion of the cabinet and the ACC-FFT module which is mounted in the center right portion of the
cabinet.

1.6 Optional Modules
ACC-AAM25 Audio Amplifier Module
An optional second identical audio amplifier can be plugged into connector P3 located in the lower
center of the main circuit board in the ACC-25/50 Series. This amplifier also provides 25 watts of
power at 25 VRMS and can therefore be used to expand system power to 50 watts (providing dual 25
watt speaker circuits) or it can be used as a backup amplifier. An option module can also be used to
convert the 25 VRMS output to 70.7 VRMS.
NOTE: For ease of access, all wiring should be connected to the terminals on the main circuit
board terminal blocks TB5, TB6, TB9 and TB10 prior to installing the secondary Audio Amplifier
Module.
FC-XRM70 Transformer Module 70.7 VRMS
This optional module plugs into connector P1 of the Audio Amplifier Module and provides conver-
sion from 25 VRMS to 70.7 VRMS at full rated 25 watts output power.
FC-LPS Local Playback Speaker
This optional speaker module plugs into connector P2 located in the lower right section of the
ACC-25/50 Series main circuit board. This unit allows reviewing of the digital messages locally
without broadcasting over the system speakers. The optional module must be installed in order to
take advantage of the Playback feature. It may be temporarily used to test recorded messages. A
mounting kit is included for this purpose. The FC-LPS cannot be permanently mounted in the
enclosure and must be removed after use.
FC-RM Remote Microphone
The optional microphone module FC-RM, provides general paging capabilities through the remote
microphone for an audio system. Announcements can be broadcast over the speaker circuits by
depressing the Remote Microphone keyswitch. The FC-MIM Microphone Interface Module must
be installed in the ACC-25/50 or ACC-25/50ZS audio panel for connection to the FC-RM (refer to
the FC-RM Product Installation Document #51247 for installation information).

Product Description
Getting Started
An ACC-25/50ZST does not require an FC-MIM since the function of this module is incorporated
in the ACC-FFT Fire Fighter Telephone module which is included with the ACC-25/50ZST. The
Remote Microphone Module is connected directly to the ACC-FFT Fire Fighter Telephone module
NOTE: Paging operations initiated from within the ACC-25/50 Series main panel will override the
remote microphone.
ACC-EPM External Page Module
This optional module provides an interface to external non-emergency paging equipment. When
activated, a contact closure will switch the external paging equipment into the ACC-25/50 Series
speaker circuits if the circuits have not been activated by the ACC-25/50 Series panels for emer-
gency use. Any emergency/fire activation or local paging will override the ACC-EPM input. Pag-
ing from non-emergency equipment is prohibited during AC loss condition to preserve battery
power.

amplifiers which, in turn, transmit an audio signal over the system speakers. All field wiring for
the circuits is power-limited and supervised for opens and ground faults. Note that zero impedance
to ground will cause a ground fault.
CMD1 and CMD2 Command Input circuits can be independently field programmed to be triggered
by a contact closure or by the reverse polarity of a Notification Appliance Circuit.

4.5.11 Fire Fighter Telephone: ACC-25/50ZST Only
The ACC-25/50ZST provides a telephone interface for up to 24 remote FFT jack locations and per-
mits up to six (local phone handset plus five FHS-F remote phone handsets) simultaneous connec-
tions. Two available styles of remote FFT jacks are the FPJ-F and the RPJ-F, both providing a
standard audio plug interface for the FHS-F handsets. The RPJ-F also houses a keyswitch for
remote paging operations. S3 switch 7 on the ACC-25/50ZST motherboard (ACC-MCB) must be
set to ON.
Communication on the Telephone Loop
When a Fire Fighter plugs the handset into one of the remote FFT locations, a ring-back tone will
be heard at the remote location, the Answer Call LED will flash and the piezo will sound on the
ACC-FFT module located in the ACC-25/50ZST main panel. The user at the main panel can
answer the remote call by picking up the local handset and pressing the Answer Call pushbutton,
which turns the Answer Call LED on steady and terminates the ringback tone. Both parties can
now converse by depressing the respective push-to-talk switch on the handsets.
Additional handsets (up to 4 more) can plug-in and converse in a party-line format. Proper termi-
nation of communication requires that all remote jacks be unplugged and that the Answer Call
pushbutton be pressed. If this procedure is not followed, a system fault condition will occur.

Section 5: Application Examples
The AUDIO•COMMAND•CENTER•25/50, AUDIO•COMMAND•CENTER•25/50ZS, and
AUDIO•COMMAND•CENTER•25/50ZST are voice evacuation control panels which can be used,
with a variety of Fire Alarm Control Panels, to provide emergency audio messages. This chapter
contains a few application examples and is not meant to provide a comprehensive list of all possible
ACC-25/50 Series applications.
5.1 One Speaker Circuit on ACC-25/50
A very basic application consists of one ACC-25/50 Series with one amplifier and a single speaker
circuit. This configuration is suitable for small facilities requiring no more than 25 watts of output
power. A single fire evacuation message will be generated during an alarm condition from the host
FACP or manually by a message push-button.
In this application, the NAC from the host FACP is connected to CMD1. The CMD1 out terminals
are then terminated with an EOL resistor for the FACP's Style Y NAC or the terminals are wired
back to the host FACP for a Style Z NAC. S3 DIP switches 1, 2 and 3 are set to OFF which causes
a 60 second message to be sent to the speaker circuit when CMD1 input is activated. S5 DIP
switch 5 is set to OFF which causes CMD1 input to be activated by a reverse polarity condition.
CMD3, CMD4, and CMD5 inputs require End-of-Line resistors and CMD2 cannot be used to trig-
ger the ACC-25/50.
IMPORTANT! When CMD1 is configured for reverse polarity, the NAC cannot be Coded.

Another application consists of one ACC-25/50 Series with one amplifier and a single speaker cir-
cuit. A second amplifier can be installed as a backup if desired. This configuration is suitable for
small facilities requiring no more than 25 watts of output power. A single 60 second fire evacua-
tion message will be generated during an alarm condition from the host FACP or manually by a
message push-button.
In this application, the NAC from the host FACP is connected to CMD1. The CMD1 out terminals
are then terminated with an EOL resistor for the FACP's Style Y NAC or the terminals are wired
back to the host FACP for a Style Z NAC. S3 DIP switches 1, 2 and 3 are set to OFF which causes
a 60 second message to be sent to the speaker circuit when CMD1 input is activated. S5 DIP
switch 5 is set to OFF which causes CMD1 input to be activated by a reverse polarity condition.
CMD3, CMD4, and CMD5 inputs require End-of-Line resistors and CMD2 cannot be used to trig-
ger the ACC-25/50.
IMPORTANT! When CMD1 is configured for reverse polarity, the NAC cannot be Coded.

sage Control switch settings).
This application consists of one ACC-25/50 Series with two speaker circuits which requires instal-
lation of the optional second amplifier. This configuration is suitable for small facilities requiring
no more than 50 watts of output power and a 60 second fire evacuation message.
In this application, the addressable FACP directs tone or voice messages to either of the speaker cir-
cuits via the control modules which are connected to the CMD1 and CMD2 inputs. S3 DIP
switches 1, 2 and 3 are set to OFF which configures CMD1/CMD2 to direct the Fire Message to the
Auditorium/Classroom speakers respectively. S5 DIP switch 5 is set to ON which causes CMD1
input to be activated by a contact closure and S5 DIP switch 6 is set to ON which also causes
CMD2 input to be activated by a contact closure.
The system can also be manually activated via the keypad by selecting the Auditorium and/or
Classroom Speakers zone push-button followed by the selection of the Fire Message push-button
or by using the microphone to make an announcement. Manually deactivating a speaker circuit is
accomplished by pressing the activated (illuminated) output zone push-button. Refer to the keypad

5.4 Two Speaker Circuits on ACC-25/50
Control switch settings).
This application consists of one ACC-25/50 Series with two speaker circuits which requires instal-
lation of the optional second amplifier. This configuration is suitable for small facilities requiring
no more than 50 watts of total output power. In this application, the addressable FACP utilizes
addressable control modules, which are connected to CMD1 through CMD5 inputs, to direct one of
the five voice messages to both speaker circuits.
S3 DIP switches 1 and 3 are set to ON and 2 is set to OFF. This causes CMD1 to activate the Fire
Message, CMD2 to activate the Fire Alert Message, CMD3 to activate the Tornado Message,
CMD4 to activate the Chemical Spill Message and CMD5 to activate the All Clear Message. S5
and S6 DIP switches are set to ON which causes CMD1 and CMD2 inputs respectively to be acti-
vated by a contact closure.
The system can also be manually activated via the keypad by selecting any of the Message push-
buttons on the keypad. Manually deactivating the speaker circuit is accomplished by pressing the
activated (illuminated) Audio On/Off push-button. To terminate the voice message, press the illu-
minated message push-button. Refer to the keypad example in Figure 5.3.
All Call Paging is possible by first pressing the All Call push-button on the keypad and then keying
the microphone to make an announcement. Refer to the keypad example in Figure 5.4

Application Examples
5.6 ACC-25/50 and ACC-25/50DA Installation
Audio•Command•Center•25/50 Connection to Multiple
Audio•Command•Center•25/50 Distributed Audio Panels (see Table 2.7 on page 37
for Message Control switch settings and ACC-25/50DA Manual Doc. 52265).
This application consists of one ACC-25/50 and two ACC-25/50DA panels, supplying 150 watts of
output power. The addressable FACP directs one of the five voice messages to both ACC-25/50
speaker circuits and also manages the routing of audio in the ACC-25/50DA panels via the control
modules on the SLC Loop. Audio from the first amplifier of the ACC-25/50 is input to the ACC-
25/50DA via the audio riser.
The ACC-25/50 is configured for single zone operation by setting S3 DIP switches 1 and 3 to ON
and DIP switch 2 to OFF. This causes CMD1 to activate the Fire Message, CMD2 to activate the
Fire Alert Message, CMD3 to activate the Tornado Message, CMD4 to activate the Chemical Spill
Message, and CMD5 to activate the All Clear Message. The FACP can route the message gener-
ated by the ACC-25/50 to the speaker circuits of the ACC-25/50DA by activating the control mod-
ule connected to CMD1 of the ACC-25/50DA or it can select the ACC-25/50DA’s local message
by activating the control module connected to CMD2.
All Call paging is possible by pressing the All Call button on the keypad of the ACC-25/50. This
will activate the Master Command Bus and trigger the ACC-25/50DA speaker circuits. Keying the
microphone will allow announcements to be made on all speaker circuits.
The Audio Command Center (ACC-25/50) can be used for
systems requiring up to 50 watts of audio power.
Any FACP can be used for automatic control.
The Audio Command Center Distributed Audio (ACC-25/50DA)
can be added to increase audio power above 50 watts.

Section 6: Power Supply Calculations
6.1 Overview
This section contains instructions and tables for calculating power supply currents in alarm and
standby conditions. This is a four-step process, consisting of the following:
1. Calculating the total amount of AC branch circuit current required to operate the system
2. Calculating the power supply load current for non-fire and fire alarm conditions and
calculating the secondary (battery) load
3. Calculating the size of batteries required to support the system if an AC power loss occurs
4. Selecting the proper batteries for your system
6.2 Calculating the AC Branch Circuit
The audio distribution panel requires connection to a separate, dedicated AC branch circuit, which
must be labeled FIRE ALARM. This branch circuit must connect to the line side of the main
power feed of the protected premises. No other non-fire alarm equipment may be powered from
the fire alarm branch circuit. The branch circuit wire must run continuously, without any discon-
nect devices, from the power source to the transponder. Overcurrent protection for this circuit must
comply with Article 760 of the National Electrical Codes as well as local codes. Use 14 AWG
(2.00 mm2) wire with 600 volt insulation for this branch circuit.
The ACC-25/50, ACC-25/50ZS and ACC-25/50ZST require 1.5 amps from the AC branch circuit.
6.3 Calculating the System Current Draw
6.3.1 Overview
The secondary power source (batteries) must be able to power the system during a primary power
loss. To calculate the non-fire alarm load on the secondary power source, use Calculation
Column 1 in Table 6.3 . The ACC-25/50 must support a larger load current during a fire alarm con-
dition and primary power loss. To calculate the fire alarm load on the secondary power source, use
Calculation Column 2 in Table 6.3 .
When calculating current draw and the battery size, note the following:
•
•
‘Primary’ indicates that the audio panel is being powered by AC
‘Secondary’ indicates that the audio panel is being powered by battery backup during AC
failure
•
All currents are given in amperes (A) and refer to the DC current being supplied by the panel.
Table 6.1 shows how to convert milliamperes and microamperes to full amperes
To convert....
Multiply
Example
Milliamperes (mA) to
amperes (A)
mA x 0.001
3 mA x 0.001 = 0.003 A
Microamperes (µA) to
amperes (A)
µA x 0.000001
300 µA x 0.000001 = 0.0003 A

Calculating the System Current Draw
Power Supply Calculations
6.3.2 How to use Table 6.2 to calculate system current draws
1. Enter the quantity of devices in both columns.
2. Enter the DC current draw where required. Refer to the Fire•Lite Device Compatibility
Document for compatible devices and their current draw.
3. Calculate the current draws for each in both columns.
4. Sum the total current for each column.
5. Copy the totals from Column 1 and Column 2 to Table 6.3 on page 100.
Following are the types of current that can be entered into Table 6.2 :
Calculation Column 1 - The standby current load that the audio panel must support (from
the batteries) during a non-fire alarm condition and a loss of AC power.
Calculation Column 2 - The alarm current draw that the audio panel must support (from
the batteries) during a fire alarm condition and a loss of AC power
Table 6.2 contains two columns for calculating current draws. For each column, calculate the cur-
rent and enter the total (in amps) in the bottom row. When finished, copy the totals from Calcula-
tion Column 1 and Calculation Column 2 to Table 6.3 on page 100.

Appendix B: Addressable Module Connections
When configured with an addressable FACP such as the MS-9200UDLS, MS-9200UD,
MS-9200C(E), or MS-9600, the AUDIO•COMMAND•CENTER•25/50 Series may be triggered
either by the FACP main NAC output or from addressable control modules. Figure B.1 illustrates
CMD1 triggered by an addressable control module. The addressable control module may trigger
the ACC-25/50 Series via reverse polarity (shown) or relay contact. The FACP monitors the ACC-
25/50 Series for faults while in the standby or alarm state by wiring a monitor module to the trouble
contacts as shown in Figure B.1. Activation of the addressable control module is controlled by the
FACP. Refer to the MS-9200UDLS, MS-9200UD, MS-9200C(E), or MS-9600 manual for addi-
tional information.

D.1 MS-9600, MS-9200UDLS and MS-9200UD
The ACC-25/50ZS and ACC-25/50ZST can be automatically triggered via the ACS serial link by
the MS-9600 (version 2 or higher), MS-9200UDLS and MS-9200UD (version 2 or higher) to trans-
mit one of five messages over selected speaker circuits. This is accomplished by zone program-
ming at the FACP.
Annunciation of remote Fire Fighter Telephone locations on the ACC-FFT keypad (ACC-
25/50ZST only) is also transmitted via the ACS serial link. This is accomplished by point pro-
gramming at the FACP.
D.1.1 Overview
The ACC-25/50ZS and ACC-25/50ZST provide 8 speaker circuits standard via the ACC-ZSM
Zone Splitter Module. Expansion to 24 speaker circuits is possible by adding ACC-25/50DAZS
panels. The ACC-25/50ZS and ACC-25/50ZST also have the ability to generate and direct one of
five messages to specific speaker circuits.
The MS-9600, MS-9200UDLS, and MS-9200UD communicate with the ACC-25/50ZS and ACC-
25/50ZST over the ACS annunciator terminals. The ACS Annunciator option for ACS address 01
must therefore be enabled in the FACP programming. When this option is enabled, FACP zones
Z33 through Z56 are dedicated as output zones for speaker circuits 1 through 24 respectively.
FACP Zone 32 is dedicated to turn on all speaker circuits. The FACPs will then allow the installer
to program individual addressable devices to any of the speaker circuits using the Zone Setup
menu. In addition, one of five messages can be generated over the selected speaker circuit.
To annunciate remote Fire Fighter locations in the ACC-25/50ZST, ACS address 07 must be
enabled in the MS-9200UDLS or address 05 for version 4 or higher; or ACS address 07 for the MS-
9600. When this option is enabled, SLC points 75-98 on the MS-9200UDLS or SLC points 135-
158 on loop #1 of the MS-9600 are dedicated to FFT 1-24 indicators on the ACC-FFT keypad.
All faults on the ACC-25/50ZS and ACC-25/50ZST are sent upstream via the ACS link to the MS-
9600, MS-9200UDLS, or MS-9200UD and are indicated as an ACS Fault on the display.
Important Notes:
1. For proper operation, a message must be assigned to each zone that is programmed to activate
an audio speaker circuit.
2. The message repeat setting on the ACC-25/50ZS and ACC-25/50ZST should be set to infinite.
This will ensure that lower priority activated zones will continue to broadcast the voice
message.
3. CMD inputs are not used for activation of the ACC-25/50ZS and ACC-25/50ZST, however,
4.7K ELRs must still be connected across CMD3, CMD4, and CMD5.
4. When implementing annunciation of remote FFT locations, the ACC-25/50ZST defaults to
receive only mode for ACS address 05 or ACS address 07.
D.1.2 Basic MS-9600/MS-9200UD/MS-9200UDLS & ACC-25/50ZS/T
Step-By-Step Install/Setup
1. Connect ACS wiring from FACP to ACC-25/50ZS or ACC-25/50ZST.

4. Activate individual devices to ensure proper programming
Table D.4 FACP Programming Steps
ACS Annunciator
The ACC-25/50ZS and ACC-25/50ZST communicate with the FACP via the ACS link. Enable the
ACS Annunciator address 01 as described in the appropriate FACP manual. For ACC-25/50ZST
using annunciation of remote FFTs, enable address 05 for the MS-9200UDLS and address 07 for
the MS-9600. The ACS programming options can be accessed by entering Programming Mode
and selecting Option Modules from the list of programming options.
ANN-BUS Annunciator
The ACC-25/50ZS and ACC-25/50ZST communicate with the FACP via the ANN-BUS link.
Auto-configure the ANN-BUS Annunciator as described in the appropriate FACP manual. The
ANN-BUS programming options can be accessed by entering Programming Mode and selecting
Option Modules from the list of programming options.
Zone Assignment
Zones must be assigned to each addressable input device in order to activate the appropriate output
device(s). Program each device to a zone as described in the appropriate FACP manual. Device
programming can be accessed by entering Programming Mode and selecting Point Program from
the list of programming options.
Note that when the ACS/ANN-BUS Annunciator option is enabled at the FACP, speaker circuits at
the ACC-25/50ZS or ACC-25/50ZST are automatically assigned dedicated zone numbers. These
zone numbers can then be programmed to addressable input devices which will allow the input
device to activate the programmed speaker zone.
The following table lists the zone numbers that are automatically assigned to each speaker circuit.
Note that the ACC-ZSM Zone Splitter Module installed in the ACC-25/50ZS or ACC-25/50ZST
provides 8 Style Y (Class B) speaker circuits. Additional speaker circuits can be added using the
ACC-25/50DAZS.

Table D.5 Speaker Circuit Zone Assignments
Note that Zone 32 is assigned to all speaker circuits. If an addressable device programmed to Zone
32 is activated, the message programmed to Zone 32 will be generated to all speaker circuits. The
exception is when one or more devices programmed to Zones 33 through 40 is also activated. If the
newly activated zone is programmed to a message with a higher priority then Zone 32, the higher
priority message will be generated to all circuits.
IMPORTANT! Messages have a priority scheme with Message 1 having the highest priority and
Message 5 having the lowest priority. For example, If an addressable device activates a speaker cir-
cuit programmed to generate Message 5, that message will be generated over the selected speaker
zone. If later, another device activates a speaker circuit programmed to generate Message 3, Mes-
sage 3 has a higher priority then Message 5 and will therefore be generated over both activated
speaker zones. The highest priority message will always be generated over all activated speaker
circuits.
Programming Tips for MS-9600, MS-9600LD, MS-9200UDLS, and MS-9200UD
It is important to note that Message 1 is assigned to Zone 00 (General Alarm) as a default. A mes-
sage, however, will not be generated over the speaker circuits unless one of the following program-
ming steps is completed:
•
•
For General Alarm applications, all input points must have an audio zone assigned to it:
Z32 to activate all audio zones
OR
Z33 to Z56 for specific audio zone control
For non-General Alarm applications where input devices and/or messages are mapped to spe-
cific zones, Message 1 must be removed from Zone 00 programming.
Message Assignment - Speaker Specific
The ACC-25/50ZS and ACC-25/50ZST have the capability of generating up to five different mes-
sages. Any one of the five messages can be programmed to each of the speaker circuit Zones 32
through 56. For example:

Message Assignment - Zone Specific
The FACP can be programmed to allow a specific addressable input device to generate one of five
messages over any speaker circuit. Any one of the five messages can be programmed to each of the
available zones (Zone 1 through Zone 99). In the following examples, assume that Zone 5 is pro-
grammed to Message 1, Zone 7 is programmed to Message 2, Zone 8 is programmed to Message 3,
and Zone 35 is not programmed to a message.
•
if two devices are being programmed and the first addressable input device is programmed to
Zone 7 and Zone 35, and a second addressable input device is programmed to Zone 5 and Zone
35, activation of the first addressable input device (address 12 in the example below) will
cause Message 2 to be generated over speaker circuit 3. (Table D.5 on page 109). If the sec-
ond addressable device (address 20 in the example below) is also activated, Message 1 will
now be transmitted over speaker circuit 3 since Message 1 has a higher priority then Message
2.

D.2 MS-5210UD
Refer to the MS-5210UD manual, Document #50193, for panel specific information. The ACC-
25/50ZS and ACC-25/50ZST can be automatically triggered by the MS-5210UD to transmit one of
five messages over selected speaker circuits. This is accomplished by zone and relay programming
at the MS-5210UD, DIP switch programming in the ACC-25/50ZS or ACC-25/50ZST and various
wiring schemes.
Important! When installing/configuring the MS-5210UD zones for ACS control of the
ACC-25/50ZS/T, NON-FIRE types should not be assigned to any ACC-25/50ZS/T audio zone(s)
unless the NON-FIRE programmed relay is controlling at least one of the CMD inputs of the ACC-
25/50ZS/T.
D.2.1 Overview
The ACC-25/50ZS and ACC-25/50ZST provide 8 speaker circuits standard via the ACC-ZSM
Zone Splitter Module. Expansion to 24 speaker circuits is possible by adding ACC-25/50DAZS
panels. The ACC-25/50ZS and ACC-25/50ZST have the ability to generate and direct one of five
messages to specific speaker circuits.
D.2.2 MS-5210UD Individual Zone Control With One or Two
Messages
In this configuration, the MS-5210UD provides automatic, individual audio zone (1 through 8)
control of the ACC-25/50ZS or ACC-25/50ZST via the ACS serial link. The optional LED-10IM
must be installed and enabled in the MS-5210UD programming. The Relay Closure outputs of the
MS-5210UD are used to trigger Message #1 (Fire Evacuation) and Message #2 (Chemical Spill) on
the ACC-25/50ZS or ACC-25/50ZST via the CMD1 and CMD2 inputs.

MS-5210UD
Programmed Activation by FACP
If only the generating Fire Evacuation announcement (Message #1) to individual audio zones is
desired, do not connect the MS-5210UD Relay outputs to the ACC-25/50ZS or ACC-25/50ZST
CMD inputs. In this case, the activation of the audio zones via the ACS link will automatically trip
the Fire Evacuation message to the ACS link selected zone.
Manually deactivating a speaker circuit is accomplished by pressing the activated zone push-button
on the ACC-ZPMK keypad. Manual activation of the audio system can be performed by selecting
zone push-buttons(s) on the ACC-ZPMK and then pressing either of the Message buttons. All-Call
Paging is possible by first pressing the All-Call push-button on the ACC-25/50ZS or
ACC-25/50ZST main keypad and then pressing the push-to-talk switch on the microphone.
All faults on the ACC-25/50ZS or ACC-25/50ZST are sent upstream via the ACS link to the MS-
5210UD and are indicated by illuminating the System Trouble LED on the MS-5210UD.

MS-9200(E)
D.3 MS-9200(E)
The ACC-25/50ZS and ACC-25/50ZST can be automatically triggered via the ACS serial link by
the MS-9200(E) to transmit one of five messages over selected speaker zones. This is accom-
plished by zone programming at the FACP.
D.3.1 Overview
The ACC-25/50ZS and ACC-25/50ZST provide 8 speaker circuits standard via the ACC-ZSM
Zone Splitter Module. Future development will allow expansion to 24 speaker circuits. The
ACC-25/50ZS and ACC-25/50ZST also has the ability to generate and direct one of five messages
to specific speaker zones.
The MS-9200(E) communicates with the ACC-25/50ZS/T over the ACS annunciator terminals.
The Annunciator option must therefore be enabled in the FACP programming. When this option is
enabled, FACP zones Z33 through Z56 are dedicated as output zones for speaker circuits 1 through
8 (plus 9 through 24 on ACC-25/50DAZS panels) respectively. FACP Zone 32 is dedicated to turn
on all speaker circuits. The FACP will then allow the installer to program individual addressable
devices to any of the speaker zones using the Point program option. Message 1, which is generated
by the ACC-25/50ZS/T, will be directed to each activated speaker circuit.
All faults on the ACC-25/50ZS/T are sent upstream via the ACS link to the MS-9200(E) and are
indicated as an ACS Fault on the display.
When audio annunciation of NON-FIRE events is required, assign NON-FIRE type modules to
audio zone(s) and a control module to the same audio zone(s). The control module should be used
to control a CMD input of the ACC-25/50ZS/T.
Important: The message repeat setting on the ACC-25/50ZS/T should be set to infinite. This will
ensure that lower priority activated zones will continue to broadcast the voice message.
D.3.2 Basic MS-9200 & ACC-25/50ZS/T Step-By-Step Install/Setup
Example #1 - Individual Audio zone control and individual control of all voice messages:
In this example, the MS-9200 can route the selected voice message (1-5) to activated audio zones.
Zone programming in the FACP is used to map the appropriate audio zone (32-56) and activate the
CMD input on the audio panel via the SLC:
1. Connect ACS wiring from FACP to ACC-25/50ZS/T.
2. Set ACS Address wheels on ACC-ZPMK for address 01.
3. Connect CMD inputs of the ACC-25/50ZS/T to modules on the SLC loop of the MS-9200
FACP.
4. Set DIP switches 1, 2, and 3 on Switch S1 of the ACC-ZPMK for operation with the MS-9200
FACP.
5. Set DIP switches 6, 7, and 8 on Switch S1 of the ACC-ZPMK for the number of
ACC-25/50DAZS panels installed.
6. Set Switch SW1 on the ACC-ZSM for one or two Audio Amplifier (ACC-AAM25)
configuration.
7. Set Switch SW2 on the ACC-ZSM for Style Y (Class B) or Style Z (Class A) speaker circuit
wiring.
8. Set DIP switches 1, 2, and 3 on Switch S3 of the ACC-25/50ZS/T motherboard for Single
Zone with activation of 2-5 messages.
9. Record any new messages into the ACC-25/50ZS/T.
10. Enable ACS communication and program zones (32-56) in the MS-9200 FACP.
11. Program modules on the SLC loop for CMD input activation.
Example #2 - Individual Audio zone control and only the Fire Evacuation voice message:

MS-9200(E)
Programmed Activation by FACP
In this example, the MS-9200 can route the Fire Evacuation message (message #1) to the activated
audio zones via zone programming. The CMD inputs are not used to activate the audio panel. The
audio panel defaults to activating the Fire Evacuation voice message.
1. Connect ACS wiring from FACP to ACC-25/50ZS/T.
2. Set ACS Address wheels on ACC-ZPMK for address 01.
3. Set DIP switches 1, 2, and 3 on Switch S1 of the ACC-ZPMK for operation with the MS-9200
FACP.
4. Set DIP switches 6, 7, and 8 on Switch S1 of the ACC-ZPMK for the number of
ACC-25/50DAZS panels installed.
5. Set Switch SW1 on the ACC-ZSM for one or two Audio Amplifier (ACC-AAM25)
configuration.
6. Set Switch SW2 on the ACC-ZSM for Style Y (Class B) or Style Z (Class A) speaker circuit
wiring.
7. Set DIP switches 1, 2, and 3 on Switch S3 of the ACC-25/50ZS/T motherboard for Single
Zone with activation of 2 messages (the second message will not be used).
8. Record a new Fire Evacuation message for message #1, if desired.
9. Enable ACS communication and program zones (32-56) in the MS-9200 FACP,
Example #3 - Simultaneous activation of all audio zones with individual control of all voice mes-
sages:
In this example, the MS-9200 simultaneously activates all the audio zones with one of the selected
voice messages. No ACS connection is required and CMD inputs are controlled by modules on the
SLC loop. Upon activation of a CMD input, the audio panel defaults to activating all of the audio
circuits.
1. Connect CMD inputs of the ACC-25/50ZS/T to modules on the SLC loop of the MS-9200
FACP.
2. Set DIP switches 1, 2, and 3 on Switch S1 of the ACC-ZPMK for operation with Non-ACS
FACP.
3. Set DIP switches 6, 7, and 8 on Switch S1 of the ACC-ZPMK for the number of
ACC-25/50DAZS panels installed.
4. Set Switch SW1 on the ACC-ZSM for one or two Audio Amplifier (ACC-AAM25)
configuration.
5. Set Switch SW2 on the ACC-ZSM for Style Y (Class B) or Style Z (Class A) speaker circuit
wiring.
6. Set DIP switches 1, 2, and 3 on Switch S3 of the ACC-25/50ZS/T motherboard for Single
Zone with activation of 2-5 messages.

device(s). Program each device to a zone as described in the appropriate FACP manual. Device
programming can be accessed by entering Programming Mode and selecting option 2=ZONE from
the list of programming options.
Note that when the ACS Annunciator option is enabled at the FACP, speaker circuits at the
ACC-25/50ZS/T are automatically assigned dedicated zone numbers (32 through 56). These zone
numbers can then be programmed to addressable input devices which will allow the input device to
activate the programmed speaker zone.
The following table lists the zone numbers that are automatically assigned to each speaker circuit.
Note that the ACC-ZSM Zone Splitter Module installed in the ACC-25/50ZST and each
ACC-25/50DAZS provides 8 Style Y (Class B) speaker circuits.

Table D.7 Speaker Circuit Zone Assignments
Note that Zone 32 is assigned to all speaker circuits. If an addressable device programmed to Zone
32 is activated, the message will be generated to all speaker circuits. The exception is when one or
more devices programmed to Zones 33 through 40 is also activated and an addressable control
module is used to activate one of the CMD inputs on the ACC-25/50ZS/T. If the newly activated
zone is programmed to activate a message with a higher priority then Zone 32, the higher priority
message will be generated to all circuits.
IMPORTANT! Messages have a priority scheme with Message 1 having the highest priority and
Message 5 having the lowest priority. The highest priority message will always be generated over
all activated speaker circuits.

MS-5UD-3/7 and MS-10UD-3/7
Programmed Activation by FACP
D.4 MS-5UD-3/7 and MS-10UD-3/7
The ACC-25/50ZS and ACC-25/50ZST can be automatically triggered via the ANN-BUS serial
link by the MS-5UD-3/7 or MS-10UD-3/7 (version 2 or higher), to transmit one of five messages
over selected speaker circuits. This is accomplished by zone programming at the FACP.
D.4.1 Overview
The ACC-25/50ZS and ACC-25/50ZST provide 8 speaker circuits standard via the ACC-ZSM
Zone Splitter Module. Expansion to 24 speaker circuits is possible by adding ACC-25/50DAZS
panels. The ACC-25/50ZS and ACC-25/50ZST also have the ability to generate and direct one of
five messages to specific speaker circuits.
The FACPs communicate with the ACC-25/50ZS and ACC-25/50ZST over the ANN-BUS termi-
nals using the ANN-BUS protocol only.
When configuring the ACC-25/50ZS/T for use on the ANN-BUS serial link, the ACC-ZPMK’s
address wheels can be set to any address between 1 through 8 and enabled in the FACP program-
ming. When this option is enabled, FACP input zones 1 through 5 on the five zone panel corre-
spond to speaker circuits 1 through 5 on the ACC-25/50ZS/T and 1 through 10 on the ten zone
panel correspond to speaker circuits 1 through 10 on the ACC-25/50ZS/T respectively. One of the
input zones can be programmed to be an All-Call Zone, which will activate all speaker circuits.
Any one of the five messages can be assigned to any of the input zones.
All faults on the ACC-25/50ZS and ACC-25/50ZST are sent upstream via the ANN-BUS link and
are indicated as a Voice EVAC Fault on the display.
Important Notes:
1. For proper operation, a message must be assigned to each zone that is programmed to activate
an audio speaker circuit.
2. The message repeat setting on the ACC-25/50ZS and ACC-25/50ZST should be set to infinite.
This will ensure that lower priority activated zones will continue to broadcast the voice
message.
3. CMD inputs are not used for activation of the ACC-25/50ZS and ACC-25/50ZST, however,
4.7K ELRs must still be connected across CMD3, CMD4, and CMD5.
4. Annunciation of remote FFT (FireFighter Telephone) locations is not possible.
D.4.2 Basic ANN-BUS Step-By-Step Install/Setup
1. Connect ANN-BUS wiring from FACP to ACC-25/50ZS or ACC-25/50ZST.
2. Set Address Wheels on ACC-ZPMK to any address from 01 through 08.
3. Set DIP Switches (1 = ON, 2 = ON, and 3 = OFF) on Switch S1 of the ACC-ZPMK for
operation with the FACP and switches 6, 7 and 8 for the number of ACC-25/50DAZS panels.
4. Set Switch SW1 on the ACC-ZSM for one or two Audio Amplifier (ACC-AAM25)
configuration.
5. Set Switch SW2 on the ACC-ZSM for Style Y (Class B) or Style Z (Class A) speaker circuit
wiring.
6. Set DIP switches 1, 2. and 3 on Switch S3 of the ACC-25/50ZS or ACC-25/50ZST
motherboard for Single Zone with activation of 2-5 messages.
7. Record any new messages into the ACC-25/50ZS or ACC-25/50ZST.
8. Enable ANN-BUS communication, Auto-configure the ANN-BUS, assign messages (1-5) to
input zones and assign All-Call zone (if desired) on the FACP.

IMPORTANT! Messages have a priority scheme with Message 1 having the highest priority and
Message 5 having the lowest priority. For example, If an input zone activates a speaker circuit pro-
grammed to generate Message 5, that message will be generated over the selected speaker zone. If
later, another input zone activates a speaker circuit programmed to generate Message 3, Message 3
has a higher priority then Message 5 and will therefore be generated over both activated speaker
zones. The highest priority message will always be generated over all activated speaker circuits.
