Section 8: AUXILIARY RELAY CONNECTIONS

This section provides the following information:

• General information about the auxiliary relay

• Wiring the auxiliary relay

• Programming the auxiliary relay

General Information

The 5110XM 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 output 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. Zones programmed for non-fire related 24 hour

audible alarm response (type 07) must be programmed to activate the auxiliary

relay output and not the bell output.

Relay Connections

The figures below show how to wire the auxiliary relay output for unsupervised

alarm output and for 4-wire smoke detector power usage.

Note: The communicator provides 12VDC power

on terminal 6 when the red jumper (W3) is intact.

FACTORY DEFAULTS

• Set for alarm activation (✴34=1)

• No zones trigger by default

(Must program ✴85, ✴86)

• 16 min. timeout(✴31=4)

NOTES:

• Use non-polarized indicating

devices

• Wiring is not supervised

• Take care not to exceed the

terminal 6 and overall system

alarm current ratings.
