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
Single Output Zone (Table 2.7 on page 37 for Message Control switch settings)
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.
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.
