The LEF-3L 3-Call Surface Mount Master Station with Selective Control Capability from Aiphone is a compact, wall or desk mount master station that is capable of selectively releasing a door or call up a camera. It is used with any LE (except LEF-3, 5, and 10 Master Stations) or LS-series (North America only) remote station. Communication can be established with each station by selecting the corresponding 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 4 stations with any combination of master 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 up to 3 door stations.
