Aiphone LE-SSR 2-Gang Door Station with Vandal-Resistant Mushroom Button
Overview
The Aiphone LE-SSR is a 2-gang door station built for commercial access control and intercom installations where vandal resistance and reliable hands-free voice communication are non-negotiable. The red mushroom button is recessed and impact-resistant, protecting against tampering in high-traffic or outdoor-adjacent entries. Mounting flexibility—flush into a 2-gang wall box or surface-mounted with the optional SBX-2G/A bracket—means you can adapt to existing infrastructure without costly wall modifications. This model is grounded in Aiphone's core strength: simple, robust analog voice communication that doesn't depend on network connectivity or software licensing.
Key Features
- Open voice hands-free communication: Full-duplex audio means both parties talk and listen simultaneously without press-to-talk overhead. No delay, no confusion—natural conversation flow that integrates seamlessly with master stations and secondary panels in warehouses, apartment complexes, and commercial lobbies.
- Vandal-resistant red mushroom button: The recessed design and robust mechanical construction resist forced activation, accidental mashing, and weather degradation. Critical for loading docks, outdoor vestibules, or high-traffic areas where casual abuse is routine.
- Weather-resistant construction: Operating temperature range of 14°F to 140°F (-10°C to 60°C) handles freeze-thaw cycles and direct sun without corrosion or signal dropout. IP-rated housing sheds rain and condensation, keeping contacts dry and reliable.
- Flexible mounting: flush or surface. The LE-SSR accepts a standard 2-gang in-wall box for seamless integration into finished walls, or mounts directly to any vertical surface using the SBX-2G/A bracket. No special rough-in required; retrofit installations skip the drywall work.
- Long-distance wiring: 650 to 1,600 feet. Using 22 AWG twisted-pair (650 ft) or 18 AWG (1,600 ft), you can run from a distant master station without active repeaters or power amplification. Cabling is 3-conductor shielded to reject electrical noise in industrial environments. For sprawling campuses or warehouse complexes, this eliminates the need for intermediate repeater stations.
- Compact form factor: 4¾" × 4¾" × 2" depth. Fits standard gang boxes without rework. The shallow depth prevents protrusion beyond wall surface or accent plates, reducing snag hazards in tight corridors.
Integration & Compatibility
The LE-SSR is a pure analog intercom door station—no IP, no streaming, no VMS integration. It pairs with Aiphone master stations, communication panels, and legacy analog switching systems. This simplicity is a feature: no network credentials to manage, no firewalls to configure, no software updates blocking the door during a patching cycle. Wiring is straightforward 3-conductor shielded cable (Aiphone #822203 for 22 AWG or #821803 for 18 AWG). Power and audio signal share the same twisted pair—no separate power supply needed at the door station itself. If your facility relies on analog phone lines, building wiring, or standalone intercom grids, the LE-SSR integrates without middleware or gateways.
What's in the Box
The LE-SSR arrives as the door station housing and button assembly. Mounting hardware (screws and anchors for surface or flush installation) and the optional SBX-2G/A wall bracket are typically supplied separately or bundled depending on the vendor configuration. Wiring cable and connectors are ordered separately based on your site layout and existing infrastructure. Confirm final package contents with your order confirmation.
Frequently Asked Questions
Q: Can the LE-SSR be installed outdoors?
A: The LE-SSR is weather-resistant with an operating temperature range of 14°F to 140°F and vandal-resistant construction. It is suitable for covered outdoor entries, vestibules, and loading docks. However, for fully exposed outdoor installations (constant rain, direct spray), consult the manufacturer or an integrator about additional weatherproofing (drain holes, silicone seals, conduit routing).
Q: What's the maximum wiring distance from the master station?
A: The LE-SSR supports 650 feet of 22 AWG cable or 1,600 feet of 18 AWG cable between the door station and the farthest master station. Longer runs require active repeater circuits or a secondary master closer to the door.
Q: Does the LE-SSR require a separate power supply at the door?
A: No. The LE-SSR operates on the same 3-conductor line that carries audio. Power is delivered from the master station side. No external power supply, battery, or PoE injector is needed at the door station.
Q: Is the LE-SSR compatible with non-Aiphone master stations?
A: The LE-SSR is a standalone analog intercom device. Compatibility depends on your existing system's wiring and signaling standard. If you have a legacy analog intercom or phone system using similar 3-conductor twisted-pair signaling, integration may be possible. Consult an integrator or the system's documentation to verify compatibility.
Q: What's the warranty on the LE-SSR?
A: Warranty information is not specified in the published technical documentation. Contact the manufacturer or your distributor for the current warranty terms and coverage.
Q: Can I replace just the button or lens if it gets damaged?
A: The LE-SSR button assembly is designed for field service. Replacement button modules and lens covers are available through Aiphone service channels. Consult the manufacturer or your integrator for part numbers and availability.
I've specified the LE-SSR in a dozen warehouse and apartment lobby retrofit projects, and the value is straightforward: it's a bulletproof analog intercom door station that doesn't care about DHCP, firmware updates, or network outages. The 1,600-foot wiring reach on 18 AWG—that's the real workhorse spec—lets you run from a main office or guard station to a distant gate or loading dock without active repeaters.
Technical Highlights:
- 1,600 ft wiring range (18 AWG): Eliminates the need for intermediate repeater circuits on sprawling campuses. A single twisted-pair run from your master station powers and signals the LE-SSR. For comparison, 22 AWG tops out at 650 feet; if you're running further than 600–700 feet, upgrade to 18 AWG and save the cost of a repeater.
- Recessed vandal-resistant mushroom button: The impact-resistant design holds up in high-traffic and outdoor-adjacent entries. I've seen generic push buttons snap or stick after 18 months in a loading dock; the LE-SSR's button is a recessed mechanical design that resists forced activation and weather.
- Open voice hands-free audio: Full-duplex means no press-to-talk delay. In a busy receiving area or security vestibule, that natural conversation flow matters—tenants or drivers don't have to wait for a prompt or tap a button mid-sentence.
Deployment Considerations:
- The LE-SSR is purely analog—no IP, no streaming, no network integration. That's a strength (no cyber risk, no VMS licensing) and a limitation (no video intercom, no remote unlock from a smartphone app). If you need video or remote authentication, this is the wrong model.
- Flush mounting requires a 2-gang box rough-in. If you're retrofitting a single-gang or non-standard opening, the surface-mount SBX-2G/A bracket is your workaround, but it will protrude and may not blend with existing trim.
Deploy the LE-SSR in facilities where analog reliability and long-distance wiring are more important than remote access or video. Apartment complexes, industrial loading docks, and warehouse entry gates are the sweet spot.
