Installing the Digital Door Box

The Digital Door Box (P/N 80560) 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. To answer the chime, the called extension user
just lifts the handset. This lets the extension user talk to the visitor at the Door Box. The Door Box is conve-
nient to have at a delivery entrance, for example. It is not necessary to have company personnel monitor the
delivery entrance; they just answer the Door Box chimes instead.
The number of Digital Door Boxes you can install is limited by the System Load Factor. See DS2000 Load
Factor Calculations on page 1-3 for more.
A Digital Door Box can control the CPU relay contacts. See Door Box Relay Control on page 4-4 for more.
The Digital Door Box is a weather-tight unit, with an operating temperature range of 0 to 45 degrees C (32 to
113 degrees F) and a relative humidity of 10-95%, non-condensing. It is not intended for outdoor installation.
Any available 16DSTU PCB port can support a Digital Door Box.
To install the Digital Door Box (Figure 4-3):
1. Snap open the Door Box case.
2. Punch down one end of a two-pair twisted station cable on the extension block as shown in Figure 4-3
Connecting a Digital Door Box on page 4-3.
3. Run the station cable through the hole in the back of the Door Box.
4. Strip the conductors back about 1/2 inch and connect to the Door Box terminals.
5. Snap the Door Box cover back onto the base.
