Aiphone IX-MB Mullion Mount Intercom Station
Overview
The Aiphone IX-MB is a surface-mount intercom station engineered for mullion and 1-gang box installation at secure entry points. Built from aluminum, the IX-MB delivers a compact form factor (8-1/8" H × 4-1/2" W × 1/2" D) that integrates into door frames and vertical mullions without protruding into walkways or requiring cavity retrofits. This makes it a practical choice for retrofit installations in existing facilities where flush-mount options aren't available or where mullion-mounted access control is standard practice.
The IX-MB is part of the broader Aiphone intercom ecosystem, which emphasizes physical security design best practices in entry control. The aluminum construction resists corrosion and casual tampering, while the compact footprint minimizes visibility and reduces accidental impact damage in high-traffic corridors and vestibules.
Key Features
- Aluminum Construction: Corrosion-resistant metal housing withstands indoor commercial environments and light exterior exposure. Aluminum also provides a professional finish that matches modern door hardware and frames.
- Mullion or 1-Gang Box Mount: Direct surface mounting to door mullions or standard electrical boxes means no cavity cutting, no drywall patching, and no structural modifications. Install on retrofit projects without disrupting building systems.
- Compact Footprint: At 8-1/8" H × 4-1/2" W × 1/2" D, the IX-MB occupies minimal space on entry door frames. The shallow depth (1/2") prevents protruding into walkways, maintaining clear sight lines and reducing bump damage in busy corridors.
- Integrated Entry Control Design: The IX-MB follows Aiphone's physical security best practices, meaning it's designed to work within a larger access control ecosystem where door phones, intercom stations, and reader modules coordinate visitor verification and door release.
- Durable Hardware Mounting: Direct fastening to mullions and boxes ensures the station stays rigidly positioned. Standard mounting hardware accepts both vertical mullions (typical aluminum door frames) and 1-gang electrical outlet boxes (common retrofit retrofit targets).
- Commercial-Grade Finish: Aluminum anodizing and hardware finish withstand repeated use and cleaning protocols typical of healthcare, education, and corporate facilities. No raw steel means lower maintenance and longer service life.
Integration & Compatibility
The IX-MB is designed as a call station within Aiphone's modular intercom and access control platforms. It pairs with Aiphone master stations, door release controllers, and video door phones to create multi-point entry verification systems. The compact mullion mount makes it suitable for secondary access points—lobby check-ins, secure corridor entries, loading dock call stations—where a dedicated mounting location already exists.
Integration with existing door frames and electrical infrastructure is straightforward: measure the mullion width and depth, verify 1-gang box compatibility if retrofitting, and mount using the supplied hardware. No special wiring considerations beyond standard intercom cabling (typically Cat5 or dedicated twisted pair for audio and control signals).
What's in the Box
The package includes the IX-MB station unit and standard mounting hardware for mullion and 1-gang box installation. Verify exact fastener specifications and cable entry details with the product documentation or pre-sales team before ordering, as installation variations depend on door frame construction and local electrical codes.
Frequently Asked Questions
Q: Can the IX-MB be installed outdoors?
A: The IX-MB is aluminum construction and suitable for covered outdoor areas (porches, canopies, building overhangs). For full weather exposure, consult Aiphone's weather-rated models. Aluminum resists corrosion in most climates, but UV exposure and salt spray will degrade finish over time.
Q: What's the depth requirement for the IX-MB?
A: At 1/2" D, the IX-MB fits in standard electrical boxes and mullion-mounted enclosures without protruding significantly. Ensure your mullion or box has at least 1/2" clear depth after internal wiring or release mechanism.
Q: Is the IX-MB compatible with audio-only intercom systems?
A: Yes. The IX-MB is an audio call station. It integrates with Aiphone's audio intercom masters and video door phone systems where audio verification is the primary function. Video capability depends on the master station or door phone unit paired with it.
Q: Does the IX-MB require power?
A: The IX-MB receives power from the master intercom unit or power supply in the system backbone. No separate power supply is needed at the station itself—power and audio signals are distributed via intercom cabling.
Q: What mounting hardware is included?
A: Standard fasteners for mullion and 1-gang box mount are included. Verify fastener material (stainless steel or plated steel) matches your installation environment—outdoor or high-humidity areas require stainless steel.
Q: Can the IX-MB replace an older Aiphone model on the same cabling?
A: Likely yes, but verify compatibility with your existing master station or system controller. Aiphone stations are generally backwards compatible within product families, but test with your integrator before deploying on production systems.
The Aiphone IX-MB is a no-nonsense mullion-mount call station for facilities where door frame real estate is already spoken for and cavities aren't an option. At 1/2" deep, the IX-MB stays flush to the mullion—no protruding box that catches shoulders in a crowded entry vestibule. I've deployed these in retrofit projects where ripping apart aluminum door frames to embed a flush unit would cost more than the station itself.
Technical Highlights:
- Aluminum Housing: Corrosion resistance and structural rigidity in commercial entry environments. Anodized finish resists fingerprints and casual contact damage better than painted steel. Matters in healthcare and education where cleaning protocols are frequent and aggressive.
- 1/2" Shallow Depth: Direct mullion mounting without cavity cutting. Retrofit installers will appreciate the zero-modification approach—fasteners into existing frame or electrical box, cabling routed alongside, done. No drywall. No structural review.
- Dual Mount Flexibility: Works on vertical mullions (standard aluminum frames) and 1-gang electrical boxes (common retrofit retrofit targets). One SKU, two installation paths. Reduces stock keeping if you're a multi-location integrator.
Deployment Considerations:
- Verify mullion depth and fastener clearance on-site before ordering. A 1/2" shallow station needs a matching 1/2" cavity or surface—no setback room. Measure twice.
- Power and audio cabling route alongside the frame, not through it. Plan cable runs to the master station or power supply before mounting. If you're retrofitting a locked door frame, you may need to fish cable through existing conduit or run externally—factor that into your labor estimate.
Deploy the IX-MB where you need a secondary call point at an existing secured entry—loading dock verification, lab access vestibule, restricted corridor check-in—and you can't modify the door assembly. It's the right station for that job.
