Section 1: Product Description

The AUDIO•COMMAND•CENTER•25/50DA Distributed Panel (ACC-25/50DA) and 
AUDIO•COMMAND•CENTER•25/50DAZS Zone System Distributed Audio Panel (ACC-
25/50DAZS) are single channel, 25 watt, 25 V

RMS,

 emergency voice evacuation panels which are 

designed to interface directly to the AUDIO•COMMAND•CENTER•25/50 (ACC-25/50) Series 
audio panels.  The ACC-25/50DA Series, which supports up to eight speaker circuits, can be used 
to distribute voice evacuation audio over a building’s speaker system.  The audio riser input pro-
vides automatic gain control (AGC) which compensates for any audio signal loss due to circuit 
loading or cable length, ensuring that a full output signal is delivered to the speakers.  An optional 
FC-MGM message generator is available with standard pre-recorded message or programmable 
message capability (up to sixty seconds).  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 available for backup purposes or to provide an 
additional 25 watt speaker circuit.  Optional 70 V

RMS

 conversion modules are also available for 

installations where 70 V

RMS

 speakers are to be installed or already exist.  The modular design 

allows for ease-of-serviceability.

The ACC-25/50DA can be automatically activated by the five CMD inputs from an FACP.  The 
ACC-25/50DAZS can be automatically activated via the Zone System serial communications link 
from the ACC-25/50ZS/T.

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.  

The ACC-25/50DAZS includes an ACC-ZPM Zone Page Module and an ACC-ZSM Zone Splitter 
Module.  These modules provide up to eight speaker circuits that may be manually or automatically 
activated.

Significant technological enhancements set the ACC-25/50DA Series apart from other voice pan-
els.  

These enhancements include full supervision in both active (alarm or music) and standby con-

ditions

.  

Supervision is provided for:

amplifier outputs

field wiring (shorts and opens)

optional message generator (FC-MGM)

all tone generators

optional remote microphone

If the audio riser input fails, the distributed audio panel can be programmed to switch to the built-in 
tone generator or optional FC-MGM Message Generator.  If the FC-MGM fails or is not installed, 
the tone generators on the main  circuit board can be automatically switched in as backups.

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 V

RMS

 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.

NOTE:

Music cannot be used for ACC-25/50DAZS.
