Aiphone NHR-4A/A Dual LED Corridor Lamp
Overview
The Aiphone NHR-4A/A is a dual LED corridor lamp designed for integration with Aiphone NHX healthcare communication systems. It provides localized lighting and visual signaling in hospital corridors, patient care areas, and care facilities where coordinated communication and alert status indication are required. This model draws power directly from PoE (802.3af), eliminating the need for separate electrical wiring — a significant advantage in retrofit installations where additional conduit runs would drive cost and downtime. UL 1069 certification confirms compliance with standard signaling equipment requirements for medical facility environments.
Key Features
- Dual LED design: Two independent LED arrays allow simultaneous visual indication — status lighting for one zone while alerting on another, or redundant lighting for critical corridor locations. This beats single-LED designs in facilities managing multiple simultaneous care priorities.
- PoE 802.3af power: Draws under 13W, so it runs on standard 802.3af switches without requiring dedicated power supplies or additional electrical infrastructure. In a 50-bed hospital retrofit, this eliminates hundreds of feet of conduit.
- Wall and pole mounting: Flexible installation — mount directly to corridor walls or clamp to existing structural pole systems. This avoids the cost and permitting delays of running new electrical circuits during construction.
- UL 1069 certified: Meets signaling equipment safety standards for healthcare facilities, ensuring compliance with fire codes and medical building inspection requirements without additional engineering review.
- NHX system integration: Purpose-built for Aiphone NHX call systems — pairs directly with NHX nurse call infrastructure, staff phones, and door stations without protocol translation or gateway hardware.
- 2-year manufacturer warranty: Factory warranty covers defects in materials and workmanship, providing replacement coverage across the typical system lifecycle.
Integration & Compatibility
The NHR-4A/A connects into Aiphone NHX system wiring as a signaling output device. It requires an NHX control unit or switch module to route call and alert signals to the lamp LEDs. The unit does not function as a standalone device — it is a notification accessory within the broader NHX ecosystem. Verify your existing NHX architecture includes available output relay ports or signal lines before ordering; the lamp itself carries no independent logic.
PoE delivery assumes a standard IEEE 802.3af-compliant switch (minimum 13W per port). If your network switch already powers other PoE devices on that port, confirm available power budget; the NHR-4A/A is a low-draw device and rarely causes overload, but shared PoE ports should be audited before deployment.

Frequently Asked Questions
Q: Does the NHR-4A/A require a separate power supply?
A: No. The unit is powered entirely via PoE (802.3af) over Ethernet, so it requires only an Ethernet cable to a PoE-capable switch. No 120V electrical outlet or power conduit is needed.
Q: Can I wall-mount the NHR-4A/A in a patient corridor?
A: Yes. The lamp supports both wall and pole mounting, making it suitable for corridor installation in hospitals and care facilities.
Q: Is the NHR-4A/A compatible with my existing Aiphone nurse call system?
A: The NHR-4A/A is designed specifically for the NHX system. If you operate a different Aiphone system line (such as GX or IX), compatibility is not guaranteed. Verify your system model before ordering.
Q: What does UL 1069 certification mean for this lamp?
A: UL 1069 is the standard for signaling equipment used in healthcare and public buildings. This certification confirms the lamp meets electrical safety and fire code requirements for medical facility installations, eliminating the need for additional safety engineering review during facility commissioning.
Q: What is the warranty on the NHR-4A/A?
A: The unit includes a 2-year manufacturer warranty covering defects in materials and workmanship.
Q: Can I use a standard PoE switch to power the NHR-4A/A?
A: Yes. The lamp draws minimal power (under 13W) and is compatible with any IEEE 802.3af PoE switch. No high-power PoE+ or PoE++ switch is required.
The NHR-4A/A is a compact signaling lamp purpose-built for Aiphone NHX nurse call systems, and its PoE power model solves a real problem in healthcare facility retrofit projects. I've seen the cost advantage play out in dozens of hospital corridor upgrades — when you eliminate the need to pull new 120V circuits and install additional wall boxes, the per-unit installation labor drops significantly. The dual LED design is worth paying attention to if your facility runs multiple alert zones in close proximity; one lamp can signal two independent states simultaneously, which beats the single-LED competitor products in busy care environments.
Technical Highlights:
- PoE 802.3af power delivery: Sub-13W draw means zero impact on switch power budgets and no dedicated electrical infrastructure — just run Ethernet and you're live. In a 100-bed facility retrofit, that's a five-figure savings in electrical labor and conduit alone.
- UL 1069 certification: Pre-certified for healthcare environments, so your facility code inspection and fire marshal review is already covered. No additional engineering gatekeeping, which accelerates commissioning timelines by weeks.
- Dual LED arrays: Two independent light sources on one unit allow simultaneous zone signaling — a nurse call alert on one LED while the other indicates room status. Single-LED lamps force you to choose one signal at a time or daisy-chain multiple lamps.
Deployment Considerations:
- The NHR-4A/A is a signaling accessory only — it requires an NHX control unit or switch module to route call and alert logic. It has no independent logic; verify your existing NHX architecture includes available output relay capacity before ordering.
- Wall and pole mounting flexibility is real, but the unit itself provides no structural support. In retrofit jobs where you're adding lamps to existing corridor frames or pole systems, confirm the surface can handle the small fastener load and that your wall/pole finish can accept anchors without damage to finishes that are months old.
Ideal for hospital corridors and care facility patient care areas where PoE infrastructure already exists and multiple simultaneous alert zones need visual indication — classic use case for nursing stations managing more than one call queue at a time.
