NOTE: In a multi-master system, all masters only talk to the
door station, and only one master can be on at a time.
OPERATION NOTES:
1. Only one master can be used at a time.
2. If both masters are activated, a feedback will be heard through the system when either TALK button is
pressed.
3. If feedback occurs, wait approximately 15 seconds, or until the master turns off automatically. At that
time, communication can continue normally.
INSTALLATION GUIDELINES:
1. Run 2 conductor wire from the door station to the first 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 fit 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-9S 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 modification to "Normally Closed" if a magnetic lock is used.
