WIRING DIAGRAM: Dual Master LEM-1DL System with DAK-2S Dual Master Adaptor
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 rst 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 t 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.
IMPORTANT!!!
Each master REQUIRES an individual power supply.
