Aiphone LE-SS-1G Flush Mount 1-Gang Door Station

Aiphone LE-SS-1G Flush Mount 1-Gang Door Station

Overview

The Aiphone LE-SS-1G is a stainless steel flush-mount door station designed as a sub-station for Aiphone IP intercom systems. It integrates with LEF-series (3-, 5-, and 10-channel) and LEM-1 master stations to provide open-voice hands-free communication at entry points, loading docks, warehouse access gates, and other monitored locations. The unit mounts flush into a standard 1-gang electrical box or directly to wall surfaces via an optional SBX-1G bracket. The LE-SS-1G (often searched as LE SS 1G) is built for indoor and outdoor deployment with moisture-resistant, puncture-resistant speaker construction and a weather- and vandal-resistant form factor.

Key Features

• PoE++ (802.3bt) Power: Draws power from a single PoE++ source, eliminating the need for separate 12VDC or 24VDC supply runs — simplifies wiring and reduces infrastructure cost, particularly useful in facilities where power conduit is limited.
• Flush or Surface Mount Flexibility: Installs directly into a 1-gang electrical box (4.5" H × 2.75" W × 2" D form factor) or mounts flush to drywall and masonry. Optional SBX-1G bracket allows surface mounting on exposed walls, adapting to retrofit or new-construction scenarios.
• Extended Cable Run Distances: Supports up to 650 feet at 22 AWG or 1,600 feet at 18 AWG from door station to master unit over 3-conductor shielded twisted-pair cabling (Aiphone #822203 or #821803 recommended). This reach eliminates the need for intermediate amplifiers in many warehouse and campus layouts.
• Stainless Steel Construction: Corrosion-resistant housing withstands salt air, chemical spray, and high-humidity warehouse environments without degradation. Ideal for food-processing, pharmaceutical, and coastal facilities where standard aluminum or plastic enclosures fail.
• Moisture and Puncture-Resistant Speaker: Handles condensation and accidental impact without acoustic degradation, important for wet areas (dock spray-downs) and high-traffic zones where mechanical damage is a risk.
• Weather and Vandal-Resistant Design: Sealed construction resists rain, dust, and deliberate damage, allowing deployment in covered outdoor areas (loading docks, transit shelters, parking structures) without a dedicated IP67 housing.
• Open-Voice Hands-Free Communication: No push-to-talk required — visitors and staff can speak naturally to the master station or remote personnel, reducing operational friction at busy access points.
• Wide Operating Temperature Range: Functions in −40°F to 185°F (−40°C to 85°C) environments. Supports outdoor winter climates and unheated spaces (warehouses, freezer docks, outdoor kiosks) as well as high-temperature industrial areas.

Integration and Compatibility

The LE-SS-1G is a dedicated sub-station for the Aiphone LEF and LEM intercom families. It communicates over standard 3-conductor shielded twisted-pair cabling and draws power from PoE++, requiring no additional power infrastructure. It does not function as a standalone device and must be paired with an Aiphone LEF-series master (3-, 5-, or 10-channel) or LEM-1 master station. Cabling recommendations: use Aiphone #822203 (22 AWG) for runs up to 650 feet or #821803 (18 AWG) for runs up to 1,600 feet to maintain voltage margin over the PoE++ link.

When to Choose a Different Model

If you require a video door station (to see visitors before answering), consider a video-enabled sub-station or IP video doorbell from the broader Aiphone or competing intercom lines. If you need remote access to the intercom system via smartphone or SIP integration, evaluate whether the LEF/LEM master station supports remote apps or SIP gateway modules — the LE-SS-1G itself is a simple audio device. For indoor-only, low-traffic spaces where vandal resistance is not a concern, a less robust sub-station model may reduce cost, but this unit's stainless steel and sealed design justify the investment in harsh or outdoor-exposed environments.

Frequently Asked Questions

Q: Can the LE-SS-1G be used as a standalone unit?

A: No. The LE-SS-1G is a sub-station and requires an Aiphone LEF-series (3-, 5-, or 10-channel) or LEM-1 master station to function. It cannot operate independently.

Q: What power source does the LE-SS-1G require?

A: The unit is powered via PoE++ (802.3bt). It draws power from the network link and does not require a separate 12V or 24V supply.

Q: How far can the LE-SS-1G be installed from the master station?

A: Maximum run distance is 650 feet at 22 AWG or 1,600 feet at 18 AWG shielded twisted-pair cabling from door station to master unit. Use Aiphone-recommended cabling (#822203 or #821803) to maintain voltage margin.

Q: Is the LE-SS-1G suitable for outdoor use?

A: Yes. The unit features weather- and vandal-resistant design, moisture-resistant speaker construction, and operates in −40°F to 185°F temperatures. It is rated for covered outdoor deployment (loading docks, transit shelters, parking areas) but is not rated for direct submersion or unprotected full-weather exposure.

Q: Can the LE-SS-1G mount flush into a standard electrical box?

A: Yes. The 4.5" H × 2.75" W × 2" D form factor is designed for 1-gang electrical boxes. Alternatively, use the optional SBX-1G bracket for surface mounting on exposed walls or masonry.

Q: What cabling should I use for long-distance runs?

A: Aiphone recommends 3-conductor shielded twisted-pair: #822203 (22 AWG) for up to 650 feet or #821803 (18 AWG) for up to 1,600 feet. Larger gauge wire supports longer distances while maintaining PoE++ voltage integrity.

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

The LE-SS-1G is a workhorse for distributed intercom in warehouses, manufacturing, and multi-building campuses where you need simple voice communication without video or complex routing. The PoE++ power model eliminates separate 24VDC supply runs — a real advantage when your electrical infrastructure is fully booked. The stainless steel housing is not cosmetic; it's essential if you're deploying into food, pharma, or salt-air environments where standard door stations corrode within a year.

Technical Highlights:

• PoE++ (802.3bt) single-cable power: No auxiliary power supply needed. Wired from a compatible PoE++ switch or injector, it reduces bill-of-materials cost and installation time compared to dual-run (power + signal) cabling.
• 650–1,600 ft reach via twisted-pair: Supports campus-scale deployments without intermediate amplifiers. At 22 AWG, 650 feet covers most multi-floor building runs; at 18 AWG, 1,600 feet spans large warehouses or outdoor perimeter access points.
• −40°C to 85°C operating envelope: Handles unheated outdoor docks in winter and high-temperature industrial spaces (food freezers, foundries). Few sub-stations match this range without protective enclosures.
• Stainless steel + sealed speaker: Corrosion resistance and moisture protection mean zero maintenance in wet or chemical environments. The puncture-resistant speaker tolerates the rough treatment typical of industrial access points.

Deployment Considerations:

• The LE-SS-1G is a pure audio device; if you need visitor identification or remote smartphone access, you'll need to layer a separate video doorbell or mobile app gateway on top of the LEF/LEM master station.
• Master station support is mandatory — confirm your chosen LEF or LEM master has the channel count and features (e.g., remote apps, SIP gateways) before committing. The sub-station itself offers no intelligence.
• Cable gauge matters at distance: many installers underestimate PoE++ voltage drop over long runs. Use #821803 (18 AWG) for anything over 500 feet to avoid audio dropouts or power resets.

The LE-SS-1G fits warehouse access control, dock communication, and multi-building campus deployments where durability and long-distance reach are non-negotiable and video is either handled separately or unnecessary. It's a quiet, reliable choice in harsh environments where fancier units fail.
