The LEF-3L is a compact, wall or desk mount master station able to selectively release a door or call up a camera. This 3-call master station can activate door strikes or maglocks, control external devices, call up CCTV cameras, turn on lights, or control other devices that are triggered by a relay. The control corresponds to the station where communication is established. The LEF-3L can be used with any LE- or LS-series 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. A relay (RY-PA) is required for each external device, and can be connected to provide a momentary or maintained closure. The RY-PA has a “normally open” output, but can be modified to “normally closed”. 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.
Features:
- Intermixable - any number of masters and remotes up to 4 total locations
- Selective door release, activating the door strike associated with the door where communication is established
- Press-to-talk communication at initiating master. Hands free reply from remotes or responding master
- Desk or wall mount
- Use QuikSpec to design this system
- Compatible with LE- or LS-series door stations
