SECTION 1
System Overview
The FCPS-24FS6 is a 6 amp power supply and the FCPS-24FS8 is an 8 amp power
supply. Each FCPS-24FS power supply is a compact, cost-effective, remote power
supply and battery charger which provides ADA compatible strobe synchronization.
The remote power supplies consist of a filtered 24 VDC output that can be configured
to drive four Style Y (Class B) NACs (Notification Appliance Circuits). The four
circuits can be configured for Style Z (Class A) with the optional ZNAC-4 Class A
converter module. Alternatively, the four output circuits may be configured as 24 VDC
resettable or nonresettable power outputs. The input circuits, which control the power
supply operation, are triggered by the reverse polarity of an NAC or by a 12 VDC or 24
VDC power source. The power supplies are compatible with 12 VDC and 24 VDC
control panels.
1.1 General
The FCPS-24FS power supplies can be used as remotely mounted power supplies and
battery chargers to power four noncoded or coded NACs. The Main FACP (Fire Alarm
Control Panel) NAC(s) is connected to the remote power supply input circuit(s). When
the control input circuit activates due to reverse polarity of the NAC from the FACP, the
power supply will activate its Notification Appliance Circuits.
During the inactive or nonalarm state, the power supply supervises its NAC field wiring
for short and open conditions. AC fail, battery, charger and ground fault troubles will
also be monitored by the power supply. If an NAC or power supply fault is detected,
the power supply Normally-Closed Trouble contact will open.
If an alarm condition occurs and the NAC is activated, the supervision is disabled and
the Notification Appliance Circuit is no longer supervised. Supervision of other power
supply faults such as low battery, AC loss, ground fault and battery charger trouble will
continue and may be monitored via the Trouble relay contacts.
