Aiphone NIR-31 Corridor Light 1 Name

Aiphone NIR-31 Corridor Light with One Magnetic Nameplate

Overview

The Aiphone NIR-31 is a surface-mounted corridor light designed as a visual call indicator for intercom systems. Built from fire-resistant ABS plastic, the NIR-31 mounts directly to drywall and accommodates one magnetic nameplate for room or zone identification. This is a compact accessory (5-11/16 in H × 7-1/2 in W × 15/16 in D) engineered for commercial facilities—hospitals, schools, office buildings, and multi-tenant properties—where staff need instant visual feedback that a call is incoming without checking a handset or speaker unit.

Key Features

• Fire-Resistant Housing: ABS plastic rated for fire resistance means the unit won't accelerate flame spread in code-critical environments like healthcare facilities, K-12 schools, and multi-family residential buildings where UL-rated components are mandatory.
• Surface-Mount Installation: Mounts directly to finished walls without cutting into wall cavities or running conduit—reduces installation labor and works in retrofit scenarios where raceways are impractical.
• Magnetic Nameplate Slot: One nameplate position lets you label the corridor, room number, or department. Magnetic design means you can update or replace the label without tools or fasteners.
• Compact Form Factor: 15/16 in depth keeps the unit tight to the wall surface, minimizing obstruction in narrow hallways or tight clinic corridors where wall space is premium.
• Integration with NIM Master Stations: Works as a visual annunciator paired with Aiphone NIM-series master stations (NIM-20B, NIM-40B) and sub-station networks, providing distributed call indication across multi-room or multi-floor facilities.
• Low-Profile Design: Small footprint (7-1/2 in wide) fits above or beside doorframes, under signage, or in confined spaces without cluttering the wall aesthetic in professional environments.

Integration & Compatibility

The NIR-31 integrates into Aiphone's NIM (Nurse Intercom Module) system architecture. When wired to a master station or sub-station, the light illuminates in response to incoming calls, giving nursing staff, faculty, or office personnel instant visual notification even in high-noise environments (operating rooms, shop floors, cafeterias). The unit pairs naturally with companion accessories in the NIR family—NIR-32 (two-nameplate variant), NIR-34 (four-name model), and NIR-4 (single-room call light)—allowing you to scale visual indication across corridors or departments without redesigning the wiring backbone.

Frequently Asked Questions

Q: Can the NIR-31 be used as a standalone light, or does it require a master station?

A: The NIR-31 is a slave device designed to work with an Aiphone master station (such as NIM-20B or NIM-40B) or sub-station. It will not function independently and requires wiring integration into the system.

Q: What are the wiring requirements for the NIR-31?

A: The NIR-31 connects via standard low-voltage intercom wiring to the master or sub-station. Specific wire gauge and voltage requirements are documented in the NIM Installation and Operation Manuals available through Aiphone's Knowledge Base.

Q: Is the NIR-31 suitable for outdoor or wet-location mounting?

A: No. The NIR-31 is designed for interior use only. It is not rated for outdoor, damp, or wet environments. For exterior applications, consult Aiphone's emergency tower or outdoor-rated accessory lines.

Q: Can I replace the magnetic nameplate with a custom label?

A: Yes. The single magnetic nameplate slot accepts standard magnetic label inserts. You can swap nameplates without tools, making updates straightforward for room reassignments or departmental reorganization.

Q: What is the depth of the NIR-31, and will it stick out from the wall?

A: The NIR-31 is 15/16 in (24 mm) deep. This shallow profile is designed to sit flush and tight against finished drywall, minimizing protrusion in tight hallways or passageways.

Q: Does the NIR-31 work with all Aiphone intercom models?

A: The NIR-31 is compatible with Aiphone's NIM-series systems (NIM-20B, NIM-40B master stations and associated sub-stations). It is not compatible with other Aiphone product lines such as JP, JV, or IX series. Verify compatibility with your system design before specification.

Ted Perry

The Aiphone NIR-31 fills a straightforward but critical role in healthcare and institutional intercom deployments: it gives staff instant visual confirmation of an incoming call across noisy environments where audio alone fails. I've seen plenty of call-light misses in operating suites and busy clinic hallways—the NIR-31's fire-resistant plastic housing and shallow 15/16 in profile solve that without adding bulk to cramped corridors.

Technical Highlights:

• Fire-Resistant ABS Plastic: Meets building codes for healthcare, K-12, and multi-family residential where flame-spread ratings matter. No retrofit reclassification needed when you add these to an existing facility.
• Magnetic Nameplate Design: One label slot with magnetic backing means you can relabel rooms or departments in seconds. I've watched integrators waste hours with adhesive labels that peel or fade—this avoids that headache entirely.
• Shallow 15/16 in Depth: Sits nearly flush to the wall. In tight nursing station corridors or school hallways where every inch counts, that shallow footprint keeps traffic flow unobstructed and the fixture invisible until it lights.

Deployment Considerations:

• The NIR-31 is a slave device only—it requires a master station (NIM-20B or NIM-40B) to function. Budget for the master and any sub-stations in your design; a single light won't stand alone.
• Verify wiring runs during rough-in. The NIR-31 uses standard low-voltage intercom wiring, but in retrofit scenarios with long cable runs or multiple lights per zone, you may need to plan conduit routing before drywall closure.

Deploy the NIR-31 in multi-room healthcare settings, clinic waiting areas, or educational facilities where staff respond to distributed call lights. The fire-resistant housing and simple magnetic nameplate make it the right choice for high-turnover institutional environments where code compliance and ease of relabeling both matter.
