- SUPPLEMENT TO LEF INSTRUCTIONS -
The LEF-3L is a compact, wall or desk mount master station able to selectively release a door or call up a camera.
Used with any LE-(except LEF-3,5 and 10) or LS-series (North America only) remote station, communication can be
established with each station by selecting the channel on the master station. While the channel is selected, pressing
the door release button (left of TALK button) will release only the associated door. When used for camera call-up, a relay
closure will be maintained as long as a station is selected. The system can have up to four stations, in any combination of
masters or door stations (e.g. 2 masters and 2 doors). Master-to-master communication is also a standard feature.
(If communication between masters is not required, multiple LEF-3L's can be used to talk to 3 door stations.)
