Aiphone NHR-4A/A - Dual LED Corridor Lamp

Two separate calls, distinguished at a glance from the corridor. The amber lamp lights for a bedside call and the red lamp for a bathroom call, both originating in the same patient room. Staff walking the hall can tell a bathroom pull cord activation from a bedside call cord activation without entering the room, which is the whole point of running a two-color lamp instead of a single annunciator.

A standard 1-gang box. The NHR-4A/A is a flush mount lamp, so the electrician sets a single-gang box in the corridor wall outside the patient room door and the lamp trims out flush to the wall. No proprietary back box or special enclosure is involved, which keeps it a normal rough-in for a contractor working a patient room corridor.

The bedside sub station in the patient room it serves. The NHR-4A/A takes its signal from that station, so the corridor lamp is not a standalone device, it only annunciates for the room whose sub station it is wired to. Plan one lamp per patient room opening and pull the run from that room's station rather than from a central panel.

It is a nurse call corridor lamp, part of Aiphone's NHX Series, and it is built around patient room call annunciation, amber for bedside and red for bathroom. If you want a plain status or occupancy light for an office or a lab door, this is the wrong part, because its two colors are tied to bedside and bathroom call inputs from a nurse call sub station.

Yes, it is a commercial rated device and it is specified for patient room corridors, so hospital, skilled nursing, and assisted living work are all in scope. Standardizing on it across a floor is straightforward since each unit flush mounts in a standard 1-gang box and wires to the bedside sub station in the room it covers, so every opening gets the same rough-in.

No options to specify. The NHR-4A/A is sold as a single model with no finish, handing, or voltage variations to select, so ordering is just quantity, typically one per patient room being covered. What does need planning is the wiring back to each room's bedside sub station and a 1-gang box at each corridor location.
