only when 2 relays are used

on any one channel.

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.

The LEF-3L does not have the "privacy feature", and also cannot send a call tone to the remote stations.
