DOOR BOX
Installing a Door Box (Figure 4-10, Figure 4-11)
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 2PGDAD module audio output can optionally support an analogue Door Box. In addition, you
can connect each circuit's 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 nor-
mally open. The NTCPU also provides 1 relay. This relay is defined as relay '0' in programming. The
relays on the 2PGDAD modules are numbered 1-8. The system can have up to eight Door Boxes.

A 2PGDAD Module is required for this feature.
NOTE: A 2PGDAD circuit used for an analogue Door Box cannot also be used for
External Paging.
Make sure the jumper in the 2PGDAD module for the associated Door Box is set correctly.
(Refer to Figure 4-4 JUMPER SETTINGS on page 4-3).
If a line cord was not previously connected to the 2PGDAD, complete Steps 3-4. Otherwise,
skip to Step 7.
Install an RJ11 (or RJ45) socket for each 2PGDAD module. For each module, run one-pair
station cable to the RJ11 (or RJ45) socket.
Terminate the extension leads to pins 3 & 4 for RJ11 sockets (pins 4 & 5 for RJ45).
Plug a modular line cord from the socket to the CN1 connector on the 2PGDAD module.
If wall mounting the Door Box, remove the screw on the front of the Door Box.
Remove the back half of the Door Box and attach this mounting bracket to the wall with the
two screws provided.
Connect the two-conductor station cable from the CN4 connectors within the 2PGDAD mod-
ule to the Door Box terminals. These wires must be routed through the opening in the bottom
of the Door Box mounting bracket.
The connection between the PGDAD and the door box is not polarity sensitive.
The PGDAD is not compatible with any other type of door box other than the one speci-
fied within this manual.
Replace the front half of the Door Box and reattach the screw to secure it in place.
necting the Door Box to a relay. Relay 6 is used by CH1 of the PGDAD, Relay 5 is used by
CH2.
