NX-320E Remote Power Supply

Installation Manual
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 Specifications on page 19.) Each power supply module
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.
Product contents
The NX-320E Remote Power Supply includes the following:
•Board
• Board guides
• Transformer
• Diodes (2), black wrap is for fire installation
• Resistors (2), white wrap for fire installation
You will also need the following items that are not included with the NX-320E:
• 22 gauge 4-conductor wire (Table 1 on page 4)
• Battery (Table 3 on page 6)
UL requirements
The NX-320E meets the Underwriters Laboratories (UL) standards, including the following:
• UL365 Police Station Connected Burglar Alarm Units and Systems
• UL609 Local Burglar Alarm Units and Systems
• UL864 Control Units for Fire-protective Signaling Systems
• UL985 Household Fire W a rning Systems
• UL1023 Household Burglar Alarm Systems
• UL1610 Central Station Burglar Alarm Units
When the NX-320E is part of a UL commercial fire security system, this unit is compatible with the following:
• NX-148E-CF LCD keypad
• NX-216E zone expander
• NX-507E relay expander
• 13-474 horn/strobe 15-75 CD (for proper strobe operation, change Location 6, Segment 1 from 16 to
13)
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/
NFP A 70. 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.
Installation
There are several two-holed insertion points inside the enclosure so you can install the module either
horizontally or vertically. The insertion points have a large hole and a smaller hole.
To mount the board in an enclosure, see Figure 1 and do the following:
1. Place a black plastic PCB guide in the top insertion point, grooved edge downward. The half-moon
protrusion will be in the large hole. Do not use excessive force.
2. Insert one of the included screws into the smaller hole (from the inside of the can) to secure it in place.
A screwdriver should reach through the notch that runs the length of the guide to tighten the screw.
3. Position the other PCB guide opposite the first (grooved edge up) and placed in the lower insertion
point, using the same procedure. Once you mount the guide, screw it in securely.
4. Slide the board into the grooves of both guides. The PC board should slide freely.

Installation Manual
Wiring
When you connect the unit, do the following:
• For UL commercial fire installations, use at least 18 AWG for all field wiring. We do not recommend
shielded wire.
• Use a 16.5 VAC 50 VA / 120 V, 60 Hz hard-wired transformer (GE Security #T-0002).
Do not connect multiple power supply modules in a series (cascaded). The board is wrapped in bubble wrap.
Unwrap it so you can orient yourself as you review Figure 2.

Wiring requirements
Use Table 1 to calculate your wiring requirements. We do not recommend shielded wire. For UL Commercial
Fire installations, a minimum of 18 AWG must be used for all field-wiring applications.
