FCPS-24S Series Instruction Manual —
P/N 51977:J2 7/11/2014
Section 1: System Overview
The FCPS-24S6 is a 6 amp power supply and the FCPS-24S8 is an 8 amp power supply. Each
FCPS-24S power supply is a compact, cost-effective, remote power supply and battery charger
which provides ADA compatible strobe synchronization. Each remote power supply consists 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.
The FCPS-24S6E and FCPS-24S8E offer the same features as the FCPS-24S6 and FCPS-24S8
respectively but allow connection to 220/240 VAC. Unless otherwise specified, the information in
this manual applies to both the 110/120 VAC versions and the 220/240 VAC versions of the power
supplies.
The FCPS-24S6C and FCPS-24S8C are the Canadian versions which offer the same features as the
FCPS-24S6 and FCPS-24S8 respectively. Unless otherwise specified, the information in this man-
ual also applies to the Canadian versions of the power supplies.
1.1 General
The FCPS-24S power supplies can be used as remotely mounted power supplies and battery char-
gers 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 Notifica-
tion Appliance Circuit is no longer supervised (except for shorts). Supervision of other power sup-
ply faults such as low battery, AC loss, ground fault and battery charger trouble will continue and
may be monitored via the Trouble relay contacts.
