Aiphone IX-NVP-2DCLA 3-Gang IP Audio Intercom

Overview

The Aiphone IX-NVP-2DCLA is a three-gang, flush-mountable IP audio intercom with a red mushroom button and integrated relay outputs for access control integration. Built from stainless steel with IP54 weather and vandal resistance, this model operates over standard 802.3af PoE (drawing just 3.36W) and works as a standalone audio entry point or as part of a larger IX | IXG video intercom system. The IX-NVP-2DCLA is SIP-compliant and compatible across the full Aiphone IX and IXG product families, making it a flexible choice for campuses, multi-tenant buildings, and distributed access control deployments.

Key Features

• 802.3af PoE Power: Draws only 3.36W, meaning no dedicated power run to the door station—standard PoE switches handle power and data on one cable. Reduces installation cost and simplifies wiring in retrofit applications.
• Dual-Output Relay Architecture: Two Form A relays and one Form C relay connected to the mushroom button; one separate 24V AC/DC, 500mA contact output for external devices (magnetic locks, gate motors, buzzer relays). Gives you flexibility to trigger multiple access control zones or door strikes from a single call.
• Trigger Input: One dedicated trigger input lets external sensors (motion, door state, unlock request) initiate intercom calls without manual button press—useful for remote monitoring or automated visitor workflows.
• Audio Codecs G.711 and G.722: G.711 (μ-law and A-law) ensures compatibility with legacy VoIP systems and PBX equipment; G.722 delivers wideband audio (16 kHz) for clearer speech when network bandwidth allows. Volume adjusts 73–96 dB to reach busy outdoor areas or deliver emergency alerts at high SPL.
• IP54 Vandal and Weather Protection: Stainless-steel enclosure resists corrosion and casual tampering. IP54 keeps out dust and water spray—suitable for covered outdoor entry points, loading docks, and high-traffic areas. Not submersible (skip this model if you need full IP66/IP67 submersion rating).
• Wide Operating Temperature: Rated −40°F to +140°F (−40°C to +60°C) without additional heating or cooling—handles cold climates and uninsulated enclosure walls. Real-world advantage: no thermostat cabinet required in northern warehouses or outdoor parking entries.
• SIP Native and IX | IXG Compatible: Works with standard SIP phone systems and integrates seamlessly into Aiphone's modular intercom platform. One network backbone supports audio entry, video entry, emergency call, and access control signaling.

Integration and Compatibility

The IX-NVP-2DCLA pairs with Aiphone entry boxes, tenant stations, and emergency call devices on the same network segment. The Form A and Form C relay outputs connect directly to access control panels, door strike controllers, or PLC inputs—no additional relay module required. The 24V AC/DC contact output supports third-party magnetic locks or gate operators rated up to 500mA at 24V.

SIP compliance means the audio codec streams to any standards-based VoIP system (Cisco UC, Avaya, Asterisk, or cloud PBX platforms). Trigger input integration requires basic voltage sensing—most access control panels and IoT controllers offer open-collector or relay outputs that drive this input.

Physical and Environmental

The 5.5-inch height and 7.5-inch width fit standard three-gang electrical cutouts, enabling flush mounting in vestibules, entry foyers, and gatehouse walls. The stainless-steel faceplate and red mushroom button are visible from distance and meet ADA tactile button standards. Dimensions: 139.7 mm H × 190.5 mm W (depth not specified in source evidence).

Frequently Asked Questions

Q: Does the IX-NVP-2DCLA work with Milestone XProtect or other VMS platforms?

A: The IX-NVP-2DCLA is an audio-only intercom with SIP compliance; it does not output video. It integrates as an audio SIP endpoint into VMS systems that support SIP audio calls (such as Milestone with optional SIP phone modules). For full video entry capability, consider pairing with an Aiphone video entry station like the IXG-2C7.

Q: What's the maximum distance I can run PoE cable to the IX-NVP-2DCLA?

A: Standard 802.3af PoE supports up to 100 meters (328 feet) of Cat5e or better cable. At maximum distance and with other PoE devices on the same port, verify your switch's available power budget—the IX-NVP-2DCLA uses 3.36W, which is modest, but add up all devices on the same circuit. If distance exceeds 100 meters, use a PoE extender or run separate conduit power.

Q: Can I use the relay outputs to trigger a door strike and a gate at the same time?

A: Yes. The two Form A relays provide switching contact outputs; wire each to a separate door strike controller or gate operator rated for the same voltage and current (24V AC/DC, 500mA max per output). The Form C relay adds a changeover contact for logic operations if needed.

Q: What is the warranty on the IX-NVP-2DCLA?

A: Warranty terms were not specified in the available product documentation. Contact a local Aiphone sales expert or distributor for warranty duration and coverage details specific to this model.

Q: Is the IX-NVP-2DCLA suitable for outdoor use?

A: The IP54 rating and stainless-steel enclosure handle water spray and dust, making it suitable for covered outdoor areas (porches, canopies, loading dock overhangs). It is not rated for direct rain exposure or submersion; use an additional weatherproof enclosure or hood if the mounting location receives direct rainfall.

Q: What audio codecs does the IX-NVP-2DCLA support, and which should I use?

A: The unit supports G.711 (μ-law and A-law) and G.722. G.711 is the standard for legacy PBX systems and ensures broad compatibility; G.722 delivers clearer wideband speech (16 kHz) if your network and system support it. Choose based on your VoIP infrastructure and available bandwidth.

I spec the IX-NVP-2DCLA into campus and multi-tenant deployments where you need modular, standards-based audio entry without video—and where every watt of PoE power matters at scale. At 3.36W draw, you can pack dozens of these units on a single PoE+ switch without power starvation, something you cannot do with video entry stations. The relay architecture—two Form A plus one Form C, all tied to the mushroom button—gives access control integrators real flexibility: trigger a main door strike, a secondary gate, and a tenant alert simultaneously from one user press.

Technical Highlights:

• 802.3af PoE at 3.36W: Lowest power footprint in the IX family means no dedicated 24V power runs, no relay modules, just Cat5e and a standard PoE port. On a 95W PoE+ switch, you fit 28 of these units before hitting power limits—game-changer for large campuses.
• Dual Form A + Form C Relays: Two independent Form A contacts let you close two separate circuits (door strike, gate, or external relay) in parallel; the Form C changeover adds logic control for deny scenarios. Saves wiring and external control hardware.
• G.711 and G.722 Codec Support: G.711 locks in PBX compatibility; G.722 at 16 kHz brings wideband clarity for noisy loading docks or outdoor entries where speech intelligibility drives compliance (OSHA, ADA).
• IP54 Stainless Steel: Corrosion resistance and water-spray immunity matter in high-salt areas (coastal campuses, multi-family buildings near water) and rain-exposed alcoves. Real cost savings: zero enclosure replacements due to rust.
• Trigger Input for Automation: One input line driven by motion sensors, door state switches, or access panel open-collector outputs unlocks hands-free workflows—visitor approach initiates intercom announcement or nurse station alert without button press.

Deployment Considerations:

• IP54 is splash-resistant, not submersible—if your entry vestibule floods seasonally or sits exposed to direct rain, IP66 stainless units cost more but avoid water ingress and corrosion cleanup. Confirm site water exposure before ordering.
• The 24V AC/DC, 500mA contact output is shared across both Form A relays; do not exceed 500mA total load across both circuits, or relay damage and call failures follow. Modern door strikes draw 300–500mA; wire a second unit or external relay if you need to stack loads.
• Flush-mounting in three-gang cutouts assumes finished wall framing; if you're retrofitting into a pre-cast concrete or brick facade, drilling and conduit routing add labor—budget for core bits and extended installation windows.

The IX-NVP-2DCLA shines in multi-building campus security and large multi-tenant complexes where you need audio-only entry points at dozens of locations and PoE budget is tight. Pair one at each building entry, each tenant vestibule, and each loading dock, and you've built an audio intercom spine that talks to one access control panel and one VoIP system with no external power infrastructure.
