Mounting location

NHX equipment is designed for indoor use only.  NHX-80X must be wall-mounted on a UL Listed 3-gang
box or in a Listed electrical enclosure.  The enclosure should be provided with a solid noncombustible
mounting plate board for securing the NHX-80X chassis. ( Ref. NHX-80X dimensions: 460H x 340W x
98D. 18-1/8"H x 13-3/8"W x 3-7/8"D).  Locate the NHX-50M master within close proximity of the NHX-80X
CCU. (Max. 20m, 65' wiring distance)

Wiring

1. Use Aiphone specified shielded cable.  Otherwise, run wires in metal conduit to prevent any 

malfunction or noise interference.

2. CAUTION: – Risk of Electric Shock

When installing, route field wiring away from sharp projections, corners, and internal components.

Cable

For wiring between NHX-80X, NHX-50M, and sub stations, use UL Listed twisted pair cable, only copper
conductors, 22AWG min. or heavier, rated 300V.  Cable to call buttons and lamps can be either parallel or
twisted pair cable, 22AWG or heavier, UL Listed.

Power supply

For NHX-80X CCU, use the power supply exclusively designed, as listed below;
• PS-24E or PS-2420: Rated input 120V AC, 50/60Hz.  Rated output: DC 24V, 2A (Requires two units per
system).
For Zone light Model NHR-3A-4 (max. 4 per system), install a PS-24E or PS-2420 power supply for every
2 Zone lights.

Power off system resetting

When NHX system malfunctions, turn NHX-80X power switch off and on again, and entire system will be
reinitialized.  The reset switch on NHX-80X is used when initializing NHX-80X for sub stations.  The reset
switch on NHX-50M is used when checking connection of sub stations.

Zone light installation

Zone light will indicate which zone has a call placed at one to max. 4 locations in the facility.
• Permitted distance: 165’ with 18AWG (50m with 1.0mmø) from the NHX-80X.
