LEF-3L
3-Call Master Station with Selective Control Capability (Door Release or Camera Call-up)
Used with LE-D, LE-DA, LE-DL, LS-NVP/B Door Stations
- 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- 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. 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.

OPERATIONS & SPECIFICATIONS
OPERATION:
1. Pressing the call button at the door station will activate a tone, plus light the red channel LED indicator at the
master. The tone will be momentary, and the light will remain activated for approximately 20 seconds.
2. The person at the master station answers the call by pressing the selector button with the lit LED. If the LED has
already gone out, the call can still be answered by pressing the selector button.
3. Communication at the master station is "press-to-talk, release-to-listen". Communication at the door station is
hands free.
4. If the "Camera Call-up" feature is included, the associated relay will provide a maintained closure as long as the
station is selected at the master.
5. With communication established to a door station, pressing the door release button (marked with key symbol, left
of TALK button) will activate the door release mechanism at the corresponding door. The door release button
will
be non-functional if a station button is not pressed.
6. When the conversation is completed, the OFF button must be pressed to disengage the call.
