Aiphone lef-3c 3 Call Semi-flush Master Station

Product Description

The AIPHONE lef-3c is a semi-flush mount, selective call, open voice master station designed for small intercom systems. It supports a maximum capacity of 4 stations total, allowing any combination of sub stations and master stations within that limit. The lef-3c operates in an open voice format, meaning communication channels remain open without requiring a push-to-talk action. Licensed low-voltage technicians and security system installers typically handle this type of equipment in both residential and light commercial settings.

The lef-3c fits applications where a compact, wall-recessed master station is needed to manage calls across a limited number of intercom points. Typical install scenarios include small office entry systems, residential multi-room intercom setups, and light commercial door communication systems. The unit supports an all-call function to broadcast to all stations simultaneously, though this feature requires the BG-10C accessory. Any combination of sub and master stations can be used as long as the total count does not exceed 4.

Installation Notes

Installation should be performed by a licensed low-voltage technician in accordance with applicable local codes and NEC guidelines for communication systems. Power down the intercom system completely before wiring or mounting any station. Semi-flush mount installations require a suitable wall cutout and backbox to recess the unit properly. Do not exceed the 4-station system capacity, as doing so may result in unreliable operation.
