Aiphone NIR-2 Call Reset Button
Overview
The Aiphone NIR-2 is a wall-mounted call reset button designed to clear active call signals on Aiphone intercom systems. Built from fire-resistant ABS plastic, the NIR-2 mounts flush into a standard 1-gang electrical box, making it a straightforward addition to existing intercom infrastructure in hospitals, schools, offices, and multi-tenant buildings where staff need quick manual control over call status.
Key Features
- Fire-Resistant ABS Construction: Material meets fire safety requirements for institutional and commercial installations, reducing liability in environments like hospitals and schools where fire codes are strictly enforced.
- 1-Gang Flush Mount: Fits standard US electrical boxes, eliminating the need for custom cutouts or surface-mounted housings. Integrates seamlessly with existing wall infrastructure during renovation or new build.
- Compact Footprint (4¾" H × 2¾" W × 1" D): Minimal profile ensures the button doesn't protrude excessively from the wall, reducing snag hazards in high-traffic corridors and making it suitable for tight spaces near door frames or nurse call stations.
- Simple Reset Functionality: Manual call clearing without VMS login or software interaction. Critical in fast-paced environments (emergency departments, hotel front desks, dormitories) where staff need instant tactile feedback and don't want to depend on network connectivity.
- Intercom System Integration: Works with Aiphone NIM-series master stations (NIM-20B, NIM-40B) and compatible door stations. Standardizes call management across distributed intercom zones.
Installation and Wiring
The NIR-2 requires only low-voltage wiring back to an Aiphone master station or control module. No PoE, no data networking, no special power supply beyond standard 48V DC intercom power (such as the IS-PU-UL listed separately). Flush mounting means surface preparation is limited to standard drywall or plaster repair. Installation takes minutes for trained A/V technicians familiar with 1-gang box work.
Deployment Context
Use the NIR-2 in any Aiphone NIM-based intercom installation where manual call clearing is preferred over software-based reset. Common scenarios include:
• Hospital nurse stations and patient rooms (critical for call-light coordination)
• K-12 school main offices and classroom intercoms
• Multi-family residential buildings with shared intercom entry systems
• Office lobbies and reception areas requiring instant call dismissal
• Parking facilities with gate intercoms where staff manually manage visitor call queues
The NIR-2's simplicity—no electronics, no batteries, no firmware—makes it a fail-safe backup for VMS-dependent reset mechanisms. If your network video management system is unavailable, physical call clearing remains operational.
Frequently Asked Questions
Q: Does the NIR-2 work with all Aiphone intercom systems?
A: The NIR-2 is designed for Aiphone NIM-series master stations (NIM-20B, NIM-40B) and compatible 48V intercom systems. Check your master station documentation or contact Aiphone support to confirm compatibility with your specific system model.
Q: What's the difference between the NIR-2 and other Aiphone call accessories?
A: The NIR-2 is a dedicated reset button. Related products include the NIR-1 (wall jack), NIR-31/32/34 (corridor lights), and NIR-4 (single room call light). Each serves a different function in the call-management workflow.
Q: Can the NIR-2 be installed outdoors?
A: No. The NIR-2 is rated for indoor use only. The fire-resistant ABS plastic is not weatherproof. Outdoor intercom installations require weatherproof enclosures or dedicated outdoor-rated Aiphone components.
Q: Is any special power supply required for the NIR-2?
A: The NIR-2 draws power from your existing 48V DC intercom power supply (the IS-PU-UL or equivalent). No additional power adapter is needed if your system is already powered.
Q: How do I know if the NIR-2 button has been pressed?
A: The NIR-2 sends a reset signal to the master station. You will see the active call light or indicator on the master station (NIM-20B, NIM-40B) clear. Visual feedback occurs at the master station, not the button itself.
Q: Can multiple NIR-2 buttons be installed in the same system?
A: Yes. Install one NIR-2 button per zone or station as needed. Each button integrates with the same master station, allowing multiple staff members at different locations to reset calls independently.
The Aiphone NIR-2 reset button is the simplest form of intercom call management you'll deploy—and that's exactly why it works in environments where staff can't afford to fumble with a VMS or wait for network latency. The fire-resistant ABS housing and 1-gang flush mount (4¾" H × 2¾" W × 1" D) mean zero installation drama: drill a hole, drop it into standard electrical box, run low-voltage wire back to your NIM master station, and you're done. I've seen the NIR-2 prevent call-queue bottlenecks in hospital nurse stations where a nurse simply needs to clear the current call light and move to the next without touching a computer.
Technical Highlights:
- Fire-Resistant ABS Material: UL-tested for institutional environments where fire code compliance is a line-item audit requirement. Non-conductive plastic eliminates shock hazards in patient care and educational facilities.
- 1-Gang Flush Mount Design: Integrates with existing wall infrastructure—no custom enclosures, no surface-mount boxes that catch lanyards or wheelchairs. Standard US electrical box means any electrician can install it.
- 48V DC Low-Voltage Wiring: Powers from your existing intercom PSU (IS-PU-UL or equivalent). No PoE, no data network, no dependency on network switches or VMS uptime. Tactile reset remains operational if your IP network is down.
Deployment Considerations:
- The NIR-2 requires wired integration back to an Aiphone NIM-series master station (NIM-20B or NIM-40B)—confirm your system matches before ordering. It is not ONVIF or network-capable; it's purely analog intercom control.
- Indoor only—the fire-resistant ABS is not weatherproof and will degrade quickly in rain or UV. Outdoor intercom zones need dedicated weatherproof Aiphone hardware.
The NIR-2 shines in multi-zone hospital intercoms, K-12 office systems, and dormitory entry gates where call-light management needs to be instant, tactile, and offline-resistant. Don't buy this for a single-station IP intercom setup or for any network-only call system—it's built for legacy Aiphone analog ecosystems where reliability outweighs feature density.
