Aiphone NIR-4S Corridor Light
The Aiphone NIR-4S is a wall-mounted corridor light designed for multi-room intercom installations where you need a visible call or status indicator at the point of entry or hallway junction. This UL-rated indicator light mounts flush to a standard 1-gang electrical box, drawing power directly from your 48V DC intercom system — no separate wiring or power supplies required.
Key Features
- Fire-Resistant ABS Plastic Construction: Meets UL flammability standards, critical for building codes in corridors, stairwells, and commercial common areas. You won't face code pushback on material compliance.
- 48V DC Operation: Draws power from your existing Aiphone intercom system infrastructure. No additional power circuit needed — one less thing to coordinate with electrical.
- Flush-Mount 1-Gang Box Installation: Installs directly into standard electrical boxes with no conduit running or surface-mounted raceway. Cleaner appearance and faster termination than standalone fixtures.
- Multi-Room System Integration: Designed as a companion to Aiphone multi-room intercom stations, providing visual feedback when calls are incoming or zones are active. Integrates seamlessly into networked intercom logic.
- Compact, Low-Profile Form Factor: 1 lb weight means no special structural support. Mounts on walls or ceilings without reinforcement or additional hardware beyond the 1-gang box.
- 2-Year Manufacturer Warranty: Covers defects in materials and workmanship, standard for intercom accessories in this class.
Integration & Compatibility
The NIR-4S is purpose-built for Aiphone multi-room systems where you need distributed call indicators across a facility. It connects to your intercom's 48V DC power rail — the same circuit that powers handsets and zone stations. Mount one in each corridor, waiting area, or office threshold so staff know when a call is incoming without being at the main station. The indicator responds to the same control logic that drives your intercom relay outputs, meaning no separate programming or third-party interface required.
If you're expanding an existing Aiphone installation or retrofitting a building with corridor-based wayfinding, the NIR-4S slides into any 1-gang electrical box without replacing existing wiring.

Frequently Asked Questions
Q: What voltage does the NIR-4S require?
A: The NIR-4S operates on 48V DC, sourced directly from your Aiphone intercom system's power supply. No separate transformer or external power input is needed.
Q: Can the NIR-4S be mounted on a ceiling?
A: Yes. The NIR-4S is designed for both wall and ceiling installation using a standard 1-gang electrical box in either orientation.
Q: Is the NIR-4S compliant with building codes?
A: The NIR-4S is UL-rated and constructed from fire-resistant ABS plastic, meeting standard building code requirements for corridor and common-area fixtures.
Q: What's the warranty coverage on the NIR-4S?
A: The NIR-4S includes a 2-year manufacturer warranty covering defects in materials and workmanship.
Q: Does the NIR-4S work with all Aiphone multi-room systems?
A: The NIR-4S is compatible with Aiphone multi-room intercom systems that provide 48V DC relay output for call indication or status signaling. Verify compatibility with your specific system model before ordering.
Q: How much power does the NIR-4S draw?
A: Power consumption specifications are not detailed in available product documentation. Contact Aiphone directly for current-draw data if power budget is a critical design factor.
I've installed plenty of Aiphone multi-room systems across office buildings and healthcare facilities, and the NIR-4S fills a real gap: giving staff visual confirmation of incoming calls without requiring them to be stationed at a handset. The 48V DC flush-mount design is straightforward — you're not wrestling with extra power circuits or conduit runs. That matters when you're retrofitting an existing building and electricians are charging by the hour.
Technical Highlights:
- Fire-Resistant ABS Plastic: UL-rated material means it passes building code inspections in corridors and common areas without exception. I've never had a code official flag this component.
- 48V DC Power Draw: Operates directly from your intercom system's power rail — no separate transformer, no additional load on your main electrical service. Critical when you're adding indicators to an already-installed system and don't want to pull a new power circuit.
- Standard 1-Gang Flush Mount: Drops into any existing electrical box, wall or ceiling. Installation time is minutes, not hours — just connect the low-voltage leads and secure the trim ring.
Deployment Considerations:
- This is a passive indicator light — it doesn't originate calls or control zones. It responds only to relay outputs from your Aiphone system, so verify that your specific intercom model supports external relay control before designing the installation.
- Power consumption specs aren't published in the standard data sheets. If you're designing a large multi-floor installation with dozens of indicators, ask Aiphone for the actual current draw per unit so you can size your 48V supply correctly. Under-sizing the PSU is the quickest way to brownout the entire system.
The NIR-4S makes sense in healthcare call-light systems, office suite intercoms, and multi-tenant commercial buildings where you need staff to know when someone is calling from a remote location. It's not a substitute for a handset or speaker station, but as a visual cue at a doorway or hallway junction, it does the job without complexity.
