Supervising the Notification Appliance Circuits
To wire the NAC using the supervision feature, perform the following steps:
Step Action
1 Install a 2K EOL resistor (Model EOLR20, supplied) across the last notification appliance on the Notification
Appliance Circuit.
2 Program Zone 6 with a 24-hour response type.
IMPORTANT – Supervision must be enabled.
The Notification Appliance Circuits will not respond unless the zones are assigned to them. For fire alarms, the
system displays “FIRE ALARM SILENCED.” This message also displays if the Notification Appliance Circuit is not
supervised.
Auxiliary Relay Connections
The FA2000C provides on auxiliary relay output which may be configured as one of the following:
• Wet 12VDC form C relay output
• Dry, unsupervised form C relay with contacts rated at 30VAC/VDC, 2A max. resistive loads
The relay (terminal 6) is set at the factory for a 12V nominal (10-14VDC) output, providing 350mA max
standby current/1A max alarm current.
The total standby current that can be drawn from the auxiliary relay and auxiliary power outputs cannot exceed
350mA. The total alarm current that can be drawn from these outputs plus the bell output cannot exceed 1A.
If configuring the relay as a dry, form C relay output, cut the red jumper labeled W3 on the PC board.
Wiring the Auxiliary Relay
The figures that follow show how to wire the auxiliary relay output for unsupervised alarm output and for 4-wire smoke
detector power usage.
