Aiphone NIR-1 Wall Jack for NIR-8 Intercom Systems
The Aiphone NIR-1 is a flush-mount wall jack accessory engineered for integration with Aiphone NIR-8 multi-station intercom systems. Built from fire-resistant ABS plastic and rated UL Listed, the NIR-1 provides a durable, code-compliant interface point in institutional, commercial, and light-industrial deployments where distributed call stations are required. The compact 1-gang box design fits standard electrical enclosures, eliminating custom mounting hardware and installation complexity.
Key Features
- Fire-Resistant ABS Construction: UL Listed material meets building codes for indoor institutional and commercial environments. Eliminates fire-rating concerns in code-inspection scenarios.
- 1-Gang Flush Mount: Fits standard electrical wall boxes without custom framing or adapters. Integrates seamlessly into existing facility electrical infrastructure.
- NIR-8 System Compatibility: Works with Aiphone NIR-8 master stations (NIM-20B, NIM-40B) and sub-station configurations. Supports both point-to-point and multi-station call routing.
- Compact Form Factor: Minimal footprint reduces visual clutter at call stations. Appropriate for hallways, entry points, and shared spaces in multi-tenant facilities.
- Durable Plastic Housing: Resists impact and environmental wear in high-traffic institutional settings. No field maintenance or corrosion concerns versus metal alternatives.
- 2-Year Manufacturer Warranty: Factory-backed warranty covers defects in materials and workmanship.
The NIR-1 is a foundational accessory for NIR-8 deployments targeting schools, hospitals, office buildings, and manufacturing facilities where staff need quick access to a central intercom station. Unlike generic wall plates, the NIR-1 is engineered specifically for Aiphone's wiring and signaling topology, ensuring reliable two-way audio and call queuing across sub-stations.
Installation is straightforward: the wall jack mounts flush to a standard 1-gang electrical box using provided hardware, and connects via standard twisted-pair wiring to the NIR-8 master or sub-station. No special tools or network infrastructure is required. Power is derived from the master station, so there are no additional circuit or PoE demands at the wall jack location.
The fire-resistant plastic construction is particularly valuable in regulated environments. Schools, hospitals, and government buildings often audit intercom accessory compliance; the UL listing on the NIR-1 eliminates inspection delays and change-order requests. In retrofit scenarios, the 1-gang form factor allows installers to repurpose existing electrical boxes that might otherwise remain vacant or require rework.
Aiphone NIR-8 systems are designed for simplicity and analog reliability — they do not require VMS integration, ONVIF, or network configuration. The NIR-1 wall jack reinforces that straightforward deployment model. For facilities already running Aiphone analog intercom infrastructure, the NIR-1 is the fastest and most cost-effective way to add call-station distribution without architectural changes to the master station or cabling plant.

We've installed dozens of Aiphone NIR-8 multi-station systems in K-12 schools and office buildings, and the NIR-1 wall jack is the workhorse of those deployments. What sets it apart is not feature richness — it's simplicity and compliance. In institutional environments, fire rating and code approval matter as much as technical performance. The UL listing on the NIR-1 eliminates a common pain point: during final inspection, facilities managers ask "Is that intercom jack fire-rated?" With the NIR-1, the answer is yes, documentation in hand. The 1-gang flush mount is equally pragmatic. Most facilities have unused electrical boxes in hallways, nurse stations, and reception areas. Rather than install a surface-mounted jack or run new conduit, you drop an NIR-1 into an existing box. We've seen this cut installation labor by 20-30 percent compared to custom mounting solutions. The plastic housing is durable enough for high-traffic public areas — we've never seen impact damage in the field — and there's zero corrosion risk, which matters in damp environments like school kitchens or basement mechanical rooms.
Technical Highlights:
- Fire-Resistant ABS + UL Listed: Meets NFPA 101 Life Safety Code requirements in institutional buildings. Eliminates code variance requests and inspections delays when adding call stations to existing intercom deployments.
- 1-Gang Box Integration: Fits any standard US electrical enclosure (1-gang, 2-gang, multi-gang). No custom fabrication, no installer skill variance — electricians and integrators alike can install this in minutes.
- Analog Wiring Simplicity: No IP addresses, no VMS, no Ethernet termination. Twisted-pair to the master station; power and audio handled by the NIR-8 chassis. Ideal for security teams without network infrastructure expertise.
- Sub-Station Flexibility: Works with any NIR-8 sub-station module in a distributed call architecture. You can add or relocate stations mid-deployment without firmware updates or system reconfiguration.
- Minimal Footprint: Compact design keeps wall clutter low in high-visibility areas like main entries, visitor check-in, and emergency response stations.
Deployment Considerations:
- The NIR-1 is a passive interface — all audio processing, call routing, and station logic resides in the NIR-8 master. Ensure the master station is properly sized for the number of sub-stations you plan to add. Aiphone publishes max sub-station counts per master model (typically 5-10 depending on the master variant).
- Twisted-pair wiring runs from the wall jack to the master station or intermediate sub-station. Budget for conduit and wire pulls if the run exceeds 50 feet. Aiphone specifies 18 AWG or larger; don't use thin speaker wire as a cost-saving shortcut.
- In retrofit installations, verify that the existing 1-gang box is accessible and that the wall structure can accommodate the flush-mount plate. Concrete block or tile surfaces may require surface-mount boxes instead.
- The NIR-1 itself carries no audio or power draw — all current is sourced from the master station. No supplementary breakers or UPS sizing adjustments needed at the wall jack location.
- Test the audio path and call routing before closing walls or finishing installations. Two-way communication verification takes minutes and prevents costly rework if wiring is miswired.
The NIR-1 is the right choice for any institution or commercial facility already standardized on Aiphone analog intercom and looking to add distributed call stations without network overhead or code complications.
