Product overview

The NX-320E is a microprocessor-controlled remote power supply module for the NetworX control panels.
The module has three programmable outputs (A, B, C) and one programmable style Y bell output. You can add
up to eight power supply modules for a total of 32 outputs. You can use the A, B, and C programmable outputs
as auxiliary power, for smoke detectors and sirens. (See
has a tamper terminal that can be used to supervise the metal enclosure. Do not use more than 2500 ft. of wire
from the NX-320E to all outgoing devices.

For UL installations, the Class II, Class III, and power-limited fire alarm circuits must be installed using FPL,
FPLP, FPLR, CLIII, CLIIIR, or CLIIIP, or substitute cable permitted by National Electrical Code ANSI/
NFPA70. If you have Class II, Class III, and power-limited fire alarm circuit conductors that extend beyond the
cable jacket, separate the wires by a 0.25 in. from all other conductors or use nonconducting tubing.
