The Aiphone LEF-10 is a selective calling, open voice master station for up to 11 total stations, in any combination of master and sub stations. Calls from a sub or door station are annunciated with a momentary tone and an LED that stays lit for about 20 seconds.
The calling master is press-to-talk, release-to-listen, and the person at the receiving station answers hands-free. A privacy feature on the master and selected subs prevents eavesdropping: a call is received, but the calling master hears the reply only after the privacy button is released. Master stations can be wall or desk mounted.
