Connecting a DSX Analog Door Box to the 2PGDAD Module

The DSX Analog Door Box (P/N 922450) is a self-contained, weather-tight Intercom unit typically used to
monitor an entrance door. The Door Box connects to a 2PGDAD Module (P/N 0891027), which in turn con-
nects to an available digital station port. Each 2PGDAD Module provides connection and relays for two door
boxes. The maximum number of DSX Analog Door Boxes you can install is determined by the number of
2PGDAD Modules, which in turn is limited only by the availability of digital station ports.
Important! Do not connect a 2PGDAD Module to station ports 21-24 (extensions 320-323).

Preparation

To prepare the 2PGDAD Module for installation:
1. Find a suitable indoor location for the 2PGDAD Module.
- The 2PGDAD Module has the same environmental requirements as a DSX keyset.
- When choosing a location, keep in mind that the front side of the module contains the status LEDs
(important for troubleshooting) while the back of the unit has the cabling access.
2. Remove the screw securing the module cover and lift off the cover.
3. Using a flat blade screwdriver, pry off the plastic disc covering the cable knockout.
4. Following standard station cabling procedures, install a modular jack connected to a digital station port
at the 2PGDAD Module location.
5. At this point in the installation, do not connect the 2PGDAD Module to a digital station port .
