Aiphone NIR-6 Call Button
The Aiphone NIR-6 is a flush-mount call button designed to extend room-to-operator intercom signaling into corridors, vestibules, break rooms, and auxiliary spaces without surface-mounted clutter. Constructed from fire-resistant ABS plastic and engineered for standard 1-gang electrical box installation, the NIR-6 integrates seamlessly into existing Aiphone NIM intercom infrastructure. It solves the common deployment problem of adding call points to institutional and commercial facilities where code compliance and aesthetic integration are non-negotiable.
Key Features
- NIM Series Compatibility: Works with NIM-20B and NIM-40B master stations. Pairs with audio door stations (NI-JA), surface-mount substations (NI-BA), and corridor signaling components (NIR-31, NIR-32, NIR-34, NIR-4) for modular system expansion.
- Fire-Resistant Material: ABS plastic rated for institutional and commercial applications. Meets building code requirements for life-safety installations without retrofitting to non-compliant materials.
- Flush-Mount Form Factor: Fits standard 1-gang electrical box. Eliminates surface-mounted hardware footprint — integrates cleanly into finished walls without visible conduit or junction boxes.
- 48V DC Powered: Operates on Aiphone IS-PU-UL 48V DC power infrastructure. Low-voltage distribution simplifies wiring through existing conduit runs and eliminates line-voltage safety concerns.
- Lightweight Mounting: 0.24 lb button assembly — minimal structural load on standard electrical box hardware. No reinforcement or backing plates required.
- UL Listed: Certified for institutional and commercial life-safety deployments. Simplifies code sign-off and facility inspection compliance.
The NIR-6 addresses a specific integration gap: institutional facilities with existing Aiphone NIM systems often need to add call points to spaces not originally designed with intercom coverage. Retrofit installation into standard wall boxes — already present in most buildings — eliminates costly new conduit runs or surface-mounted aesthetics that clash with interior finishes. The fire-resistant plastic construction ensures compliance without material substitution or special procurement.
From a deployment perspective, the NIR-6 is a scale-out component. Each call button requires a dedicated pair of wires back to the master station or a secondary wiring hub; confirm your existing 48V DC infrastructure has capacity for the additional load. The NIM-20B and NIM-40B each support a fixed number of substations and call points — verify your system has an open call-button port before committing to a multi-unit retrofit. In a 20-room facility, that's 20 pairs of wire terminating at a single master — manageable but labor-intensive if conduit is not pre-existing.
Power consumption per button is minimal (the 48V DC draw is negligible), so power-supply headroom is rarely the constraint; rather, wiring labor and port availability on the master station dictate total deployment cost. If your facility has distributed call points across multiple floors or wings, consider a secondary NIM master station paired with its own power supply to balance the load and reduce cabling runs. Aiphone's modular architecture supports this topology without licensing or software complexity.
The NIR-6 operates as a momentary call signal — pressing the button generates an alert at the master station console, not a full two-way talk channel. For facilities requiring call-point audio (e.g., a break room where two-way conversation is needed), pair the NIR-6 with a separate Aiphone substation or audio door module in the same space. This architectural flexibility is a strength; you're not locked into a single call-button type across the installation.
The NIR-6 is UL listed and compliant with institutional building codes. It carries a 2-year manufacturer warranty and is manufactured in Japan. Sourced direct from the manufacturer or U.S. authorized distributor — genuine product, no grey-market variants. For facilities standardizing on Aiphone NIM series intercom infrastructure, the NIR-6 is the native expansion component; it requires no translation adapters, third-party gateways, or software configuration. Wired integration only — no wireless or IP gateway options.

We've deployed the Aiphone NIR-6 across a range of institutional settings — hospitals, office buildings, dormitories, and light industrial facilities — and it consistently solves a real problem: retrofitting call points into existing NIM intercom systems without aesthetic compromise or major structural modification. The flush-mount design is the key differentiator. In older buildings with finished walls, adding a call point typically means either surface-mounting a button (visible conduit, wall-mounted box, clutter) or opening the wall to run new conduit. The NIR-6 leverages existing 1-gang box holes that are already present in most commercial and institutional spaces — electrical outlets, light switches, low-voltage plates — making it a low-touch retrofit. We've installed them in hospital corridor walls, nursing stations, break rooms, and vestibules where signaling from that location back to a central console is required but full two-way talk capability is not. The fire-resistant ABS plastic construction passes institutional fire codes without material substitution, which eliminates a common compliance hurdle for life-safety projects. On projects where code officials are scrutinizing every component, UL listing is valuable — it closes the conversation before it starts. The 48V DC power requirement is a non-issue if your facility already has Aiphone NIM infrastructure; the load per button is negligible, and existing power supplies rarely require upgrade just for a handful of additional call points.
Technical Highlights:
- NIM-20B and NIM-40B Compatibility: Direct wired connection to the master station call-button ports. No protocol translation, no gateway required. Immediate operability out of the box — press the button, a tone and visual alert appear at the operator console. The simplicity is operationally valuable; facility staff understand the interaction without training.
- Fire-Resistant ABS Plastic: Material passes institutional flame-spread and smoke-generation standards. Eliminates material substitution requests from building officials and simplifies documentation for life-safety system sign-off. No special handling or recycling requirements at end of life.
- Flush-Mount 1-Gang Box Fit: Standard electrical box mounting — no custom brackets, no wall reinforcement. Installation labor is minimal; typical integration takes one electrician and 30-45 minutes per location (assuming conduit is pre-existing). If conduit runs are new, that's the cost driver, not the button itself.
- Low Power Draw: 48V DC supply shares infrastructure with existing Aiphone power distribution. Multi-unit deployments (10-20 buttons) don't trigger power-supply upgrades. Verify master station has open call-button ports — that's the real constraint, not power.
- Wired Only (No Wireless): Hardwired reliability with zero dropout risk. In healthcare and life-safety contexts, hardwired call systems are often required by code or policy. No batteries, no RF interference, no missed signals.
Deployment Considerations:
- Verify master station call-button port availability before purchase. The NIM-20B and NIM-40B each have a fixed number of call-button inputs; if your system is fully subscribed, you'll need a secondary master station or a wiring hub to expand capacity. This is a hard limit, not a soft constraint.
- Confirm 48V DC power infrastructure (IS-PU-UL supply or equivalent) has wiring run to the NIR-6 location. If new conduit is required, that labor cost often exceeds the button cost. Plan conduit runs before specifying buttons.
- The NIR-6 is a call signal only — pressing it alerts the operator but does not open a talk channel. If your facility needs two-way voice at that location, add a separate Aiphone NI-BA substation or NI-JA door module in the same room. This architecture is flexible but requires clear definition of use case before installation.
- Standard 1-gang electrical box must have adequate depth (typically 1.5 to 2 inches for residential/commercial boxes). Old-work or shallow retrofit boxes may not accommodate the button's profile. Verify box dimensions during site survey.
- Install wiring with margin for future expansion. If your facility plans additional call points in adjacent spaces, consider running extra 48V DC pairs now to avoid wall reopening later. Small capex investment pays off in installation labor savings.
The NIR-6 is ideal for facilities with existing Aiphone NIM infrastructure looking to extend call-point coverage into spaces originally designed without intercom. Hospitals, offices, educational facilities, and light-industrial sites are the natural fit. Pair it with the Aiphone catalog to build a complete intercom retrofit strategy.
