SECTION 4 DOOR BOX
4.1 Installing a Door Box
The Door Box is a self-contained, water-resistant, 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. The system can have up to eight Door Boxes.
Each IP1WW-2PGDAD 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 CD-CP00 also provides
one general purpose relay. The CD-CP00 relay 0 is assigned to the door box
extension port in Program10-05-01. When the relay on the IP1WW-2PGDAD is
used, there is no need to assign the relay to the Door Box.-simply connect the relay
as detailed in the steps below for the Door Box used. The relays on the
IP1WW-2PGDADs are numbered 5-8.
The relay closes when the Door Box/external page zone is called. The
maximum applied voltage is 24vDC at 0.5A for each contact.

An IP1WW-2PGDAD is required for this option.
An IP1WW-2PGDAD circuit used for an analog
Door Box cannot also be used for External
Paging.
1. Make sure the jumper in the IP1WW-2PGDAD for the associated Door
Box is set correctly. (Refer to
Settings on page
2. If a line cord was not previously connected to the IP1WW-2PGDAD,
complete Steps 3-6. Otherwise, skip to Step 7.
3. Install a modular jack for each IP1WW-2PGDAD. For each module,
run one-pair 24 AWG station cable from the cross-connect block to a
modular jack. Ground the unused pair.
4. Terminate the extension leads to GRN/RED of the modular jack.
Terminate the unused leads to the jack.
5. Install bridging clips as required.
6. Plug a modular line cord from the mod jack to the CN1 connector on
the IP1WW-2PGDAD.
