Aiphone LEF-3L 3 Call Master Station with Selective Door Release

The LEF-3L is a compact 3-call master station able to communicate with three other stations, plus selectively release doors and control external devices. CCTV cameras, lights, or other devices can be activated through a relay, which is triggered when a communication channel is selected. The master station is equipped with a door release button to activate electric strikes or magnetic locks. A relay (RY-PA) is required for each external device and can be connected to provide a momentary or maintained closure. RY-PA has a “normally open” output, but can be modified to “normally closed”.   Main Features Provides internal communication to LEF master stations or LE door stations ABS plastic housing, selective door release LED and call-tone indicators Intermixable -- any number of masters and remotes up to 4 total stations Press-to-talk communication at initiating master, hands free at responding station Selective control of external device from master in one of two ways with relay Momentary closure while “key” button is pressed Maintained closure while the station is selected Any “LE-” series component or others compatible with the LEF series can be used LS-NVP/B Vandal proof, weather resistant remote station can be used
