IMPORTANT!!!
Each master REQUIRES an individual PT-1210N power supply.
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.
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-1DL/C is 24V DC, 1A max.
3. The EL-9S 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-1DL/C provides a "normally open" contact closure for door release.
5. If a magnetic lock is used, the door release contacts can be modified to "Normally Closed". On PC board of
LEM-1DL/C, locate and remove jumper JP03 (near door release switch). Install a jumper in the position labeled JP02 .
