The LEF-3 3-Call Master Station from Aiphone is a selective-calling open-voice style master station with a capacity of up to 4 total stations. This station can be used with the LEF- or LAF-Series Master Stations, LE-, LA-, or LS-Series Sub/Door Stations, the BG-10C Chime/Music Adapter, and the PS-1225UL power supply. Select up to 3 additional compatible masters and subs to design a custom station that will meet your specific needs. This master station can be wall mounted on a 1-gang box or ring, or it can be desk mounted for use in an office or classroom.

Incoming calls from a sub or door station are annunciated with a momentary electronic monotone and an LED that remains lit for approximately 20 seconds. Communication at the master station is press-to-talk, release-to-listen, and hands-free at the receiving station. The person at a master station can selectively call and talk with a person at any other sub or master station in the system. A privacy feature on the master and selected subs prevents eavesdropping from the master station. A call can be received, but communication back to the calling master will only be heard after the privacy button is disengaged.
