Circuits
Input Circuits - CMD1 and CMD2
•
The two input circuits are independently field programmable to accept Notification Appliance Circuits or nor-
mally open contacts. Terminals are provided to allow feed-through of the NACs, allowing placement of the
VECP anywhere along a Notification Appliance Circuit. A trouble on the VECP will cause relay contacts at
the out terminals of CMD1 to open, causing an NAC circuit trouble at the FACP. Note: The V ECP will not
open the out terminals while in alarm. Monitoring V ECP troubles while in alarm requires use of independent
trouble relay at TB1.
•
Programming CMD1 and/or CMD2 for activation on contact closure will allow activation of the amplifiers on
a normally open contact transfer to the closed condition. Contact wiring is supervised for open conditions. A
short will cause amplifier activation (contact closure).
RCA Jack
•
RCA Jack provides convenient connection to an audio source such as a tape player for recording a new digital
message. It may also be used for background music if approved by local AHJ.
Output Circuits
•
Special Application Power Output, 35 mA @ 24 VDC.
•
Optional Power Supply/Battery Charger FC-PSM(E) module provides power for the main circuit board in
standby and alarm at maximum power.
•
The optional FC-PSM(E) module also provides a 24 Volt Battery Charger (up to 17 AH batteries) @ 800 mA
maximum.
Notification Appliance Circuit
•
One NAC Speaker Circuit Style Y or Style Z with each FC-AAM25 amplifier module.
Relays
•
One Form-C Trouble Relay. Contacts are rated 2.0 amps @ 30 VDC (resistive) and 0.6 amps @ 125 VAC
(resistive)
•
When optional Power Supply/Battery Charger module is installed, one Form-C AC Loss relay is provided on
the module. Contacts are rated 2.0 amps @ 30 VDC (resistive) and 0.6 amps 125 VAC (resistive).
P1 and P5 Connectors (future use)
Local Speaker
•
Connector P2 provides a connection for an optional, removable local speaker P/N: FC-LPS, to be used for
reviewing the digital message without broadcasting over the system speakers. Refer to Figure 3-18, “Installa-
tion of Speaker Module,” on page 31. This option module must be installed to take advantage of the Playback
feature. (The FC-LPS must be removed after use).
