Aiphone LE-DA Flush Mount Door Station
Overview
The Aiphone LE-DA is a hands-free door station designed for access control and visitor communication in commercial and light-duty residential installations. This unit pairs with compatible Aiphone master stations and mounts flush into a standard 2-gang electrical back box or directly to a wall surface, making it a compact alternative to surface-mounted models. The stainless steel faceplate resists corrosion and casual vandalism in moderate-duty environments. The LE-DA delivers audio-only communication without video and relies on wired connection to a central master station — no network or PoE requirement.
Key Features
- IP33 Environmental Rating: Protects against light rain and splash, but not designed for direct hose spray or fully submersed conditions. Suitable for sheltered entries, interior vestibules, and covered porches — skip this model if the door station faces full weather exposure or high-pressure washdown.
- Hands-Free Audio Communication: Delivers two-way voice without a handset, ideal for visitors or staff who need to communicate while carrying items or wearing gloves. No push-to-talk requirement means faster guest entry workflows.
- Flush Mount Configuration: Recesses into a standard 2-gang back box (depth 2 inches) for a clean, integrated look that blends into the wall rather than protruding. Requires rough-in coordination during electrical rough-in phase — not retrofittable without drywall work. If that's not feasible, consider the optional SBX-2G/A bracket for surface mounting instead.
- Stainless Steel Faceplate: 300-series stainless steel resists rust and surface corrosion better than painted aluminum, extending service life in humid or salt-air environments. Aesthetic benefit as well — matches modern commercial hardware finishes.
- 3-Conductor Shielded Cable Requirement: Uses industry-standard 22 AWG or 18 AWG twisted-pair shielded cable. Aiphone #822203 supports runs up to 650 feet at 22 AWG; upgrade to #821803 (18 AWG) for longer runs up to 1,600 feet. This cable carries audio, control, and power from the master station — no separate power supply needed. Plan cable runs during the rough-in phase to avoid visible conduit on finished walls.
- Operating Temperature Range of 14°F to 140°F: Handles most North American climates but not extreme cold (below 0°F) or heat (above 140°F). If the door station is in an unheated garage or outdoor shelter in northern climates, verify winter performance with the master station manufacturer.
- Compact Footprint (4.5" H × 4.56" W × 2" D): Takes up minimal wall real estate and integrates easily into small entry vestibules or apartment building lobbies without overwhelming the aesthetic.
- Compatible with Aiphone LE-Series Master Stations: Works with LEF-3, LEF-5, LEF-10, and LEM-1 systems — verify your existing or planned master station model before purchase. This is not a standalone unit; pairing with a compatible master is required for operation.
Integration & Compatibility
The LE-DA integrates directly into the Aiphone LE-series ecosystem. Installation requires careful planning of the cabling route from the master station to the door station location. For buildings with structured cabling already in place, integration is straightforward. Retrofit projects may require additional wall chasing or conduit runs, which can add labor. The unit does not support network connectivity or IP-based protocols — it's a hardwired analog device designed for buildings with centralized intercom systems rather than distributed VoIP infrastructure.
When to Choose a Different Model
If your installation requires video capability, higher environmental protection (IP67 or IP68), or network-based intercom, consider alternative solutions within the Aiphone catalog or evaluate IP-based door stations from other manufacturers. If the mounting location does not allow for in-wall installation and surface mounting is not acceptable, the flush-mount constraint may rule out this model.
Frequently Asked Questions
Q: Can the LE-DA be surface-mounted instead of recessed?
A: Yes. If a 2-gang back box is not available, use the optional Aiphone SBX-2G/A bracket for direct wall mounting.
Q: What is the maximum cable run length from the master station to the LE-DA?
A: Up to 650 feet with 22 AWG cable (#822203) or up to 1,600 feet with 18 AWG cable (#821803). Longer runs may experience audio degradation; consult Aiphone technical support for runs exceeding these limits.
Q: Is the LE-DA suitable for outdoor use?
A: The IP33 rating handles light rain and splash, but not heavy rain or direct spray. Install in a covered entry or sheltered vestibule. For fully exposed outdoor doors, select a higher IP-rated model.
Q: Can the LE-DA be used with a non-Aiphone master station?
A: No. The LE-DA is designed specifically for Aiphone LE-series master stations (LEF-3, LEF-5, LEF-10, LEM-1). Compatibility with other brands is not supported.
Q: Does the LE-DA require a separate power supply?
A: No. Power is delivered through the 3-conductor shielded cable from the master station. No additional transformer or PoE injector is needed.
Q: What is the warranty period on the LE-DA?
A: Consult the documentation from your specialty retailer or contact Aiphone directly for warranty terms specific to this model and your region.

The LE-DA is a solid choice for buildings with existing Aiphone LE-series infrastructure or new installations where analog intercom is the preferred architecture. The IP33 rating is the real constraint here — it's not designed for weather-beaten entrances or high-moisture environments. If your door station faces rain splash or washdown, this model will disappoint. But for sheltered vestibules, interior lobbies, and covered porches in controlled climates, the LE-DA's flush-mount profile and stainless steel finish deliver a professional appearance without the cost and complexity of IP-based video intercom systems.
Technical Highlights:
- 3-Conductor Shielded Cable Design: Simplifies installation — no PoE negotiation, no network configuration, just wire and talk. The 650-foot and 1,600-foot reach limits (at 22 and 18 AWG, respectively) cover most commercial buildings. Plan cabling during rough-in to avoid surface-mounted conduit that looks unprofessional.
- IP33 Environmental Rating: Light splash protection is genuine, but don't mistake it for weatherproof. Heavy rain, direct spray, or condensation in unheated spaces will cause intermittent audio dropouts or component failure. Verify the installation climate before deploying.
- Operating Temperature Range (14°F to 140°F): Covers most North American climates comfortably, but unheated garages or outdoor shelters in northern regions may fall below the minimum. Verify seasonal extremes on the job site.
Deployment Considerations:
- The LE-DA is a hardwired intercom device, not a networked endpoint. If your organization is moving toward IP-based access control and visitor management, this purchase locks you into parallel infrastructure. Plan for eventual replacement when the LE-series system reaches end-of-life.
- Flush-mount installation requires coordination with the electrical contractor during rough-in. Retrofit into finished walls is labor-intensive and often impractical. If you're working with existing walls, budget for the SBX-2G/A surface-mount bracket instead.
Deploy the LE-DA in sheltered commercial entries, apartment building vestibules, and office lobbies where hands-free audio-only communication is sufficient and environmental exposure is light. It's a cost-effective, low-complexity choice for buildings already committed to Aiphone LE-series infrastructure.
