1.7.5 FCPS-24FE Remote Field Charger Power Supply for System Power Expansion
The FCPS-24FE is a compact, remote power supply with battery charger. This remote power supply consists of a fil-
tered 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 filtered power configured for resettable or nonresettable operation.
The FCPS-24FE 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 4-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.

AC Power
One of the most common applications for the FCPS-24FE remote power supply utilizes the NAC expander mode. In
this application, one or two NACs (Notification Appliance Circuits) are connected from the main control panel 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 NACs are activated, the supervision is disabled and the circuits are no longer super-
vised. 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 NAC 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-24FE Installation, Operation and Application Manual for a complete description and examples of applications.
A C304 Control Module, which can be located up to 10,000 feet (3,000 m) from the FACP, may be used to activate
the FCPS power supply. The Control Module can be powered from the FCPS auxiliary 24 VDC power output (TB3
Terminals 8 & 9) and supervised by an EOL relay.
