SPECIFICATIONS
3-Call Semi-Flush Mount Master Station
DESCRIPTION:
The LEF-3C is a selective calling open voice style
master station, used to answer calls from other
remotes or masters. The system can be designed
to include any combination of master and sub
stations. The LEF-3C can be part of a larger system
with the ability to communicate with three other
stations, plus make an All Call* and/or receive
background music*.
Incoming calls from a sub or door station sound an
electronic tone and light an LED, remaining lit for
approximately 20 seconds. Communication at the
calling master is press-to-talk, release-to-listen, and
is hands free at the responding station. The person
at the master station can selectively call and talk
with a person at any connected sub or master station
in the system. The privacy feature on the master
prevents eavesdropping from another master station.
An All Call announcement can be made from the
master if the system includes the All Call/Chime
Adaptor.
The LEF-3C flush mounts into a wall. Sub stations
are available in surface or flush mount styles, with
or without privacy. Outdoor stations are available in
surface or flush mount styles.
