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 25VRMS output to 70.7 VRMS.
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 70.7VRMS at full rated 25 watts output po wer.
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).
