IMPORTANT!!!
Each master REQUIRES an SKK-620 power supply, or 4 “C” batteries. (Do not install both on one C-ML/A.)
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, wait approximately 15 seconds, or until the masters turns off automatically. At that time,
communication can continue normally.

INSTALLATION GUIDELINES:
1. Run 2 conductor wire from the door station to the fi rst master, then continue to the second master.
2. Install the units at the desired locations. (Do not install stations back to back on opposite sides of a wall.)
3. Separate SKK-620 power supplies or four “C” batteries are required for each master station.
4. DO NOT install both a power supply and batteries at any one master.
5. Install the bare wire leg of the component module directly onto the “1” terminal of the C-ML/A’s.
6. Attach the wire coming from the “1” terminal of the C-D to the colored wire end of the component modules at both masters. (The component
modules will easily fi t inside the space available.)
7. Connect the “E” terminals between the door station and master stations.
8. If door release is included, use a separate 2-conductor wire from the “L” terminals of the masters through an AC transformer and to the door strike.
9. The EL-12S is designed for a standard wood framed door, and for light to medium usage. If a different type of door is in place, install a strike
appropriate for the door.
10. The door release button on the master station is a “Normally Open” contact closure for an electric strike. See page 3 for modifi cation to “Normally
Closed” if a magnetic lock is used.
