Setting up the NX-320-I
Overview
The NX-320-I is an auxiliary power module that can be used with the NX panel. It also has three
programmable outputs and one dedicated sounder output.
Depending the panel type, you can use up to eight NX-320-I auxiliary power modules to supply 32
outputs for the panel, 24 of which are programmable and eight are dedicated sounder outputs. The 24
programmable outputs can be used as auxiliary power, fire detector power and sounder power
outputs.
Installing the NX-320-I auxiliary power module
Each NX-320-I auxiliary power module has a tamper terminal that can be used to supervise the
casing.
When the NX-320-I auxiliary power module is connected to the NX system, the maximum total wire
run to all devices is 800 metres. Each NX-320-I auxiliary power module should be connected
individually to the NX system and not in series.
