OPERATION NOTES:
1. Only one master can be used at a time.
2. When the answering master presses the TALK button, the red LED above the OFF switch will light on both masters.
This feature is controlled by the "R" wire between masters.
3. When the OCCUPIED light is illuminated, do not press the TALK button on the non-answering master, or a feedback
will be heard throughout the system. If this occurs, turn off one of the masters (depress OFF button). At that time,
communication between the door and the answering master can continue normally.
4. There is no communication between masters.
INSTALLATION GUIDELINES:
1. Separate power supplies (12-16V AC or 12-24V DC) are required at each master station.
DO NOT CONNECT +/- WIRES BETWEEN MASTERS. Keep wires for power and communication in separate jackets.
2. The door strike can be powered from one of these power sources (as shown) or from an independent source. Door
release contact rating on the LEM-1DLC is 24V DC, 1A max.
3. The EL-12S is designed for a standard wood framed door, and for light to medium usage. If a different type of door is
used, install a strike appropriate for that door.
4. The LEM-1DLC provides a "normally open" contact closure for door release.
5. If using a magnetic lock, either the RY-18L or RY-24L relay will be required to get a normally closed contact.
