Door Box (P/N 92245) Installation
The Door Box (P/N 92245) is a self-contained Intercom unit typically used to monitor an entrance door. A visitor at the door can press
the Door Box call button (like a door bell). The Door Box then sends chime tones to all extensions programmed to receive chimes.
Your Door Box unit could be either of the designs shown at right. For installation, refer to the figure that applies to your Door Box.
Installing a Door Box
1. Locate an available 2-pin connector in a miscellaneous block.
2. For the connector chosen, cross-connect the associated wire pair
from the miscellaneous block to the cross-connect block.
3. Connect leads from the lugs on the Door Box (numbered 1 and 2 on
the figures at right) to the cross-connect block. Be sure to maintain the
proper polarity.
4. Install bridging clips as required.
5. For system connections, refer to the section that applies to your system.
6. Refer to the system's installation manual for relay connections, if required.
