ACC-25/50 and ACC-25/50DA Installation 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.
