Relays Installation
2.2.3 Special Application DC Power Output Connection
All Special Application DC power outputs are power-limited.
2.3 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).
The Alarm and Supervisory silk-screen labels reflect the factory default programming for the two
programmable relays.
Note that relay connections must be power-limited. Refer to Power-limited wiring requirements.
2.4 Notification Appliance Circuits
The control panel provides four Style Y/Class B or two Style Z/Class A NACs (Notification Appli-
ance Circuits). Each circuit is capable of 3.0 amps of current. Total system current in alarm cannot
exceed 7.0 amps (refer to “Calculating the System Current Draw” on page 174). 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 sup-
plies.

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