6 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.
NOTE:
The LEF-3L does not have the "privacy feature", and also cannot send a call tone to another master or remote
station in the system.

Magnetic locks require Normally Closed (N/C) contacts, keeping power applied to the magnet to
keep the door locked, and breaking power to release the door. These instructions explain how to
change the RY-PA relay output from Normally Open (N/O) to Normally Closed.
