Installing a Door Box

A PGD(2)-U10 ADP is required for this feature.
The Door Box 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.
Each PGD(2)-U10 ADP audio output can optionally support two analog Door
Boxes. In addition, you can connect each circuit control relay to an electric
door strike. This allows an extension user to remotely activate the door strike
while talking to a visitor at the Door Box. The control relays are normally open.
The NTCPU also provides one relay. This relay is defined as relay 0 in
programming. The relays on the PGD(2)-U10 ADP are numbered 1~8. The
system can have up to eight Door Boxes.
A circuit used for an analog Door Box cannot be used for
PGD(2)-U10 ADP
External Paging.
