OPERATION NOTES:
1. Only one master can be used at a time.
2. If both masters are activated, a feedback (squeal) will be heard through the system when either TALK button is pressed.
3. If feedback occurs, press the OFF button on one of the LEM-1DL masters.
INSTALLATION GUIDELINES:
1. Use 2 conductor shielded wire from the door station to the first master, then to the second master.
2. Install the units at the desired locations.
3. Separate PT-1210N power supplies are required for each master station. NOTE: Connect power leads to master BEFORE plugging in power supply
4. Install the bare wire leg of the component module directly onto the "1" terminal of the LEM-1DL's.
5. Attach the wire coming form the "1" terminal of the LE-D to the colored wire end of the component modules at both masters. (The component
modules will easily fit within the space available.)
6. Connect the "E" terminals between the door station and master stations.
7. If door release is included, use a separate 2-conductor wire from the "EL" terminals of the masters through an AC transformer and to the door strike.
8. The EL-12S is designed for a standard wood framed door, and for light and medium usage. If a different type of door is used, install a strike
appropriate for the door.
9. The door release button on the master station is a "Normally Open" contact closure. Contact rating is 30V AC/DC @ 1 Amp.
