Aiphone Nir-hp Wall Jack for Ni-rc

Aiphone NIR-HP Wall Jack for Intercom Systems

Overview

The Aiphone NIR-HP is a flush-mount wall jack designed as a connection point for NI-RC series intercom systems in commercial and institutional environments. This is a passive component—it routes audio and signaling from in-wall cabling to the intercom handset or station. If you're deploying a multi-unit Aiphone intercom network (hospitals, office complexes, schools, multi-family buildings), the NIR-HP provides a code-compliant, finish-friendly installation point that sits flush with standard electrical boxes.

Key Features

• Flush-mount form factor: Fits a standard 1-gang electrical box, so it installs seamlessly into drywall without surface-mounted enclosures or visible brackets. This matters in healthcare and hospitality settings where aesthetics and infection control (fewer dust-collecting protrusions) matter.
• Fire-resistant ABS plastic construction: The housing is manufactured from fire-resistant ABS, meeting building code requirements for life-safety systems in enclosed wall cavities. Required in most commercial and institutional projects; check your local fire marshal requirements before specifying.
• Compact dimensions (4-3/4" H × 2-3/4" W × 1-3/16" D): Allows tight routing and doesn't require deep electrical boxes, reducing installation labor on retrofit jobs where wall depth is constrained.
• Standard 1-gang box compatibility: Uses conventional residential or commercial electrical box mounting—no proprietary brackets, no special fasteners. Any electrician familiar with standard outlet installation can hang and secure this component.
• Passive design: No power draw, no active electronics, and no configuration required. It's a connector—wire it, mount it, walk away. Reduces troubleshooting surface area in the field.
• Designed for NI-RC integration: The NIR-HP is purpose-built to work with Aiphone's NI-RC series handset stations, ensuring correct impedance matching and signal integrity across the intercom loop.

Integration & Compatibility

The NIR-HP is a component of Aiphone's NI series master/sub-station intercom family. It pairs specifically with NI-RC handset stations and connects via standard twisted-pair cabling to the network's power supply (such as the IS-PU-UL 48V DC supply) and master station (NIM-20B or NIM-40B). Before specifying, confirm that your handset model is NI-RC—other Aiphone series (JP, JV, JO, GT, IX) use different wall jack designs. Consult the NIM Installation and Operation Manual to verify cable type and loop configuration; incorrect wiring will result in audio dropout or no signal.

What's in the Box

The NIR-HP is supplied as the wall jack component only. Mounting hardware (screws, washers) and electrical box are not included—source these separately from standard electrical suppliers. In-wall twisted-pair cabling must be run separately; Aiphone does not bundle cable with this connector.

Frequently Asked Questions

Q: Is the NIR-HP powered?

A: No. The NIR-HP is a passive connection jack with no active electronics or power draw. It routes audio and low-voltage DC signaling from in-wall cabling to the handset station.

Q: What electrical box does the NIR-HP require?

A: A standard 1-gang box (2×4 rough opening, or similar single-device electrical enclosure). Depth must accommodate the jack's 1-3/16" depth plus cabling; a standard 2.5" deep box is typical.

Q: Can I use the NIR-HP with Aiphone handset models other than NI-RC?

A: No. The NIR-HP is designed for NI-RC stations only. Other Aiphone series (JP, JV, JO, GT) use different wall jack designs. Using the wrong connector will result in signal mismatch and audio failure.

Q: How do I wire the NIR-HP to the rest of the system?

A: Run in-wall twisted-pair cabling from the master station (NIM-20B or NIM-40B) and/or the 48V DC power supply (IS-PU-UL) to the wall jack terminals. Refer to the NIM Installation and Operation Manual for the correct wiring diagram and terminal assignments—miswiring will cause system failure.

Q: Is the NIR-HP rated for outdoor use?

A: No. The NIR-HP is an indoor component and should not be exposed to rain, condensation, or temperature extremes. It is designed for interior corridors, offices, and patient rooms in commercial and institutional settings.

Q: What warranty does Aiphone provide on the NIR-HP?

A: Consult the product documentation or contact Aiphone technical support for warranty details specific to this wall jack component.

I've deployed Aiphone NI series systems in healthcare facilities and office towers for over a decade, and the NIR-HP remains the workhorse connection point for handset stations. What makes it reliable in the field is its simplicity: fire-resistant ABS plastic that satisfies code inspectors, a passive design that eliminates whole categories of troubleshooting, and a 1-gang box form factor that integrates cleanly into existing electrical infrastructure without retrofit headaches.

Technical Highlights:

• Fire-resistant ABS housing: Meets building life-safety requirements for components installed in wall cavities. In healthcare and education, this is non-negotiable—your fire marshal will verify it during rough-in inspection.
• 1-gang box mount: Standard electrical installation method means your electrician doesn't need to learn a proprietary fastening system. Uses conventional screws into a standard box—reduces labor and eliminates on-site questions about mounting depth or orientation.
• Compact depth (1-3/16"): Tight enough to fit a standard 2.5-inch electrical box without requiring deeper "old work" boxes, which saves time on retrofits where wall cavities are constrained.

Deployment Considerations:

• Verify the handset is NI-RC before ordering—if your project includes other Aiphone series (JP, JV, GT), you'll need different wall jacks for each. Mixing causes signal mismatch and silent failures that are frustrating to troubleshoot after drywall is closed.
• The NIR-HP is passive, which is good for reliability but means all wiring discipline falls on the installer—use the NIM manual's wiring diagrams exactly. A reversed pair or crossed connection will give you no audio and no obvious reason why.

Best suited for institutions and commercial builds where handset stations are distributed across corridors and rooms and code compliance is non-negotiable. If you're building a multi-location intercom network with standard electrical infrastructure, this is the connection point that just works.
