FCPS-24F(E) Remote Power Supply (System Power Expansion)
The FCPS-24F (FCPS-24FE for 220/240 VAC applications) is a compact, remote power supply and battery
charger. This remote power supply consists of a filtered 24 VDC output that may be configured to drive up to four
Notification Appliance Circuits [four Style Y (Class B) or two Style Z (Class A) and two Style Y (Class B)].
Alternately, the four Notification Appliance Circuits may be used as auxiliary regulated power configured for
resettable or nonresettable operation.
The FCPS-24F(E) may be used in a number of different applications. It may be used as a remotely mounted power
supply and battery charger powering up to four, coded or noncoded, Notification Appliance Circuits. Alternately,
any or all of these circuits may be used as 24 VDC output circuits capable of powering four-wire smoke detectors
or any device that requires filtered power. These circuits may be configured as resettable or nonresettable outputs
to expand FACP auxiliary system power.

One of the most common applications for the FCPS-24F(E) remote power supply utilizes the NAC expander
mode. In this application, one or two Notification Appliance Circuits (NACs) are connected from the main FACP
NAC output(s) to the remote power supply Control Input circuits. When these Control Input circuits activate (due
to reverse polarity of the NAC output), the power supply will activate its corresponding outputs. NAC Control
Input #1 controls power supply output circuits #1 and #2. NAC Control Input #2 controls output circuits #3 and
#4.
During the inactive state, the remote power supply supervises its NAC field wiring for short and open circuits. If
a fault is detected, the supply will enter a trouble condition and illuminate the corresponding NAC trouble LED
(Output Circuits 1-4), however, once the Notification Appliance Circuits are activated, the supervision is disabled
and the circuits are no longer supervised. Supervision of other power supply faults such as low battery, Earth
Fault, AC loss and battery charger failure will continue and may be monitored via the independent trouble relay
contact.
If a specific application requires that all four outputs activate at the same time, only one NAC control input from
the FACP is necessary. For this application, The Notification Appliance Circuit from the FACP is wired into NAC
Control Input #1 of the remote supply and then a pair of wires are connected from NAC Control Output #1 to NAC
Control Input #2. Refer to the FCPS-24F(E) Installation, Operation and Application Manual for a complete
description and examples of applications.
