Aiphone LEF-10 10 Call Selective Calling Master Station

Incoming calls from sub or door stations are annunciated with a momentary electronic tone and an LED indicator that remains lit for approximately 20 seconds. Communication at the calling master is press-to-talk, release-to-listen, while the responding station operates hands-free. The master station can selectively call and communicate with any other station in the system.

The privacy feature on the master and selected sub stations prevents monitoring from the master. A call can still be received, but audio is not transmitted back until the privacy button is disengaged. The LEF-10 supports selective door release, selective monitoring and video door entry integration. It is compatible with LE-A, LE-D, LE-DA, LE-AN and LS series sub and door stations, as well as the BG-10C chime and music adaptor.
