at full rated 25 watts output power.
FC-PSM(E) Power Supply/Battery Charger Module
This optional module plugs into connector P7 located in the lower left corner of the main circuit board thus allow-
ing the VECP to be powered from its own internal power supply. The FC-PSM module is powered by 120 VAC,
60 Hz, 1.0 amp primary power and the FC-PSME module is powered by 220/240 VAC, 50 Hz, 0.5 amp primary
power. An integral battery charger is capable of charging up to 17 Amp Hour batteries. Primary AC power to the
FC-PSM(E) is constantly monitored. Upon loss of AC power or AC brownout, the AC Loss Relay contacts
change state and the AC ON LED extinguishes. A switch option (S1) may be used to select immediate or 6 hour
delay of AC Loss Relay transfer (for independent monitoring by DACT).
FC-LPS Local Playback Speaker
This optional speaker module plugs into connector P2 located in the lower right corner of the VECP main circuit
board. This unit allows reviewing of the digital message locally without broadcasting it 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.
