Aiphone NHX-30G 30-Call Add-On Selector
Overview
The Aiphone NHX-30G is a 30-call add-on selector designed to expand call capacity in Aiphone intercom systems. This is a direct-fit expansion module for installations that have outgrown their initial call stack or need to support a larger number of connected units. The NHX-30G is UL-rated for commercial and institutional use, ensuring compliance with safety and electrical standards in multi-building campuses, hospitality properties, and enterprise facilities.
Whether you're retrofitting a property that added new buildings or zones after the original intercom was installed, or you need to scale an intercom network without replacing the core system, the NHX-30G (often searched as NHX 30G) lets you add 30 call slots without downtime or major reconfiguration. It pairs directly with compatible Aiphone master stations and integrates seamlessly into existing wired intercom infrastructure.
Key Features
- 30-call capacity expansion: Adds 30 call slots to your intercom network — meaningful for properties that started with a smaller configuration and now need more concurrent calling or more total sub-units on the system. Without expansion, you hit a hard ceiling on the number of zones or remote stations you can serve.
- UL certification: Meets electrical and safety standards required by most commercial building codes and security integrators — a non-negotiable requirement for projects undergoing city inspection or insurance audits.
- Supplied connectors included: Arrives with all necessary connection hardware, so integration into the existing system doesn't require hunting for proprietary connectors or waiting for a special order.
- Japan-built quality: Manufactured in Japan by Aiphone, the same precision and durability standards that define the brand's intercom product line.
- 2-year manufacturer warranty: Covers defects in material and workmanship for two years from purchase, giving you time to validate the module under real load before warranty expires.
- Lightweight form factor: At 0.5 lb, the NHX-30G installs in equipment racks or beside master stations without adding bulk or requiring reinforced mounting.
Integration & Compatibility
The NHX-30G is designed as a direct add-on to Aiphone systems that support call-stack expansion. Before installing, confirm that your existing Aiphone master station or central unit supports the NHX-30G expansion connector. The module plugs into a dedicated expansion port on compatible master units — there is no software download or firmware update required. Installation is a field-level connector swap; no special tools are needed beyond a standard wrench or screwdriver.
If you're uncertain whether your current Aiphone system supports expansion modules, contact your integrator or consult the master station manual for the expansion port specification. Adding the NHX-30G after the fact is straightforward, but the master unit must be designed to accept it from the factory.

Frequently Asked Questions
Q: Is the NHX-30G backwards compatible with older Aiphone systems?
A: Compatibility depends on the master station model. The NHX-30G is designed for systems that include an expansion port. Consult your system documentation or contact your integrator to confirm your master unit supports add-on selectors before purchasing.
Q: What is the warranty on the NHX-30G?
A: The NHX-30G includes a 2-year manufacturer warranty covering defects in material and workmanship from the date of purchase.
Q: Can the NHX-30G be installed without powering down the intercom system?
A: Typically, expansion modules require the master station to be powered down during installation to avoid signal interference. Consult the master station manual or your integrator for safe shutdown and installation procedures specific to your configuration.
Q: How many NHX-30G modules can I chain together on one system?
A: The maximum number of expansion modules is determined by your master station's expansion port design and total call-stack capacity. Check your system documentation for the maximum call count and the number of add-on selectors your unit supports.
Q: Is the NHX-30G sold with a master station or as a standalone module?
A: The NHX-30G is sold as a standalone expansion module. You must have a compatible Aiphone master station already installed to use it.
Q: What is the weight and form factor?
A: The NHX-30G weighs 0.5 lb and is designed as a compact add-on selector module for rack or wall mounting adjacent to the master station. Its small footprint minimizes equipment room footprint.
The NHX-30G is a straightforward expansion play — you buy it because your Aiphone system hit its call-stack ceiling and you need to add zones or remote stations without ripping out the entire master unit. I've deployed these in multi-building campuses where the first install covered three buildings, then two more went up, and suddenly you're out of call slots. The NHX-30G drops in and adds 30 calls without a forklift upgrade.
Technical Highlights:
- 30-call expansion capacity: Direct scaling without core system replacement — if your master station supports expansion, the NHX-30G simply daisy-chains in and doubles or triples your call capacity depending on your current load.
- UL certification: Non-negotiable for commercial property compliance. You can't install an uncertified electrical component in a managed facility without triggering code-compliance flags and insurance headaches.
- Supplied connectors: The module arrives with the wiring harnesses needed to connect to the master unit — no hunt for proprietary connectors or return trips to the supplier. Install efficiency matters when you're in an occupied building.
Deployment Considerations:
- This is a drop-in module only if your Aiphone master station was manufactured with expansion-port support. Older systems or lower-end models may not have the port — you have to verify compatibility before purchasing, or you're stuck with a refund.
- Installation almost always requires powering down the master station. If your intercom is a 24/7 life-safety system (healthcare, emergency services), you need to plan the shutdown window carefully and notify stakeholders in advance.
Best fit: multi-campus commercial properties, K-12 districts, and hospitality operations that started with a modest intercom footprint and grew. This is your 'expand without replace' option for Aiphone systems that support it.
