3-Call Master Station

DESCRIPTION:
The LEF-3 is a selective calling open voice style
master station with the capacity of up to 4 total
stations. The system can be designed to meet a
wide variety of needs, including any combination of
master and sub stations up to its maximum capacity.
Incoming calls from a sub or door station are
annunciated with a momentary electronic mono-tone
and an LED, remaining lit for approximately 20
seconds. Communication at the calling master is
press-to-talk, release-to-listen. Person at the receiving
station speaks hands free. The person at the master
station can selectively call and talk with a person at
any other sub or master station in the system. The
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 be heard only after the privacy button
is disengaged.
Master stations can be wall or desk mounted. Sub
stations are available in surface or flush mount styles,
with or without privacy. Outdoor stations are available
in surface or flush mount styles. A vandal proof sub
station is also available.
