AIPHONE LEF-3L Intercom Master Station Wall Mount

Compact Three-Call Master Station

The Aiphone LEF-3L is a compact intercom master station designed for residential or small commercial entry control. It supports communication with up to three remote substations from a single wall-mounted or desktop unit. A built-in door release button directly activates electric strikes or magnetic locks. The station also triggers a relay when a channel is selected to control external devices such as CCTV cameras or lighting.

Suited For Simple Multi-Point Entry

This unit suits installations that require voice communication and door release for three distinct entry points or substations. It is not suited for systems requiring more than three communication channels, hands-free voice-activation, video monitoring integration, or expansion beyond the fixed three-call capacity. Buyers needing paging, privacy modes, or programmable outputs should look at larger-capacity controllers.

Three-Call Capacity Decides Fit

The defining specification is the fixed three-call capacity, which sets the maximum number of substations that can be connected. If the project requires exactly three points of communication and door control, the LEF-3L matches that requirement. If the design calls for four or more stations, this model cannot be expanded and a different master station must be selected.
