Installation Relays
2.3.3 Special Application DC Power Output Connection
All Special Application DC power outputs are power-limited and require a ferrite bead per FCC
requirements (refer to“UL Power-limited Wiring Requirements” on page 32).
2.4 Relays
The FACP provides two programmable Form-C relays and one fixed fail-safe Form-C trouble
relay, all with contacts rated for 2.0 amps @ 30 VDC (resistive) or 0.5 amps @ 30 VAC (resistive).
2.5 Notification Appliance Circuits
The control panel provides four Style Y (Class B) or two Style Z (Class A) NACs (Notification
Appliance Circuits). Each circuit is capable of 2.5 amps of current. Total current in alarm for all
external devices cannot exceed 6.0 amps (refer to “Calculating the System Current Draw” on
page 158). Use UL listed 24 VDC notification appliances only. Circuits are supervised and power-
limited. Refer to the Device Compatibility Document for a listing of compatible notification
appliances. The NACs, which are located on the main circuit board, may be expanded via the
FCPS Series field charger/power supplies.

JP4 is used to configure TB1, Terminals
1 & 2 for:
• • Resettable Power - jumper pins 1
and 2 of JP4 as shown
• • Nonresettable Power - jumper pins
2 & 3 of JP4
NOTE: Note that relay connections may be power-limited or nonpower-limited, provided that
0.25” spacing is maintained between conductors of power-limited and nonpower-limited circuits.
Refer to UL Power-limited wiring requirements.

Note that the programmable relay
labeled as Relay 1 is factory default
programmed as Alarm and
programmable Relay 3 is factory default
programmed as Supervisory.
The relay labeled Relay 2 is fixed as a
Trouble relay and cannot be changed.
It is a fail-safe relay which will transfer
on any trouble or total power failure.
