PGDAD Module and Analog Door Boxes

Use the 2PGDAD Module to connect Analog Door Boxes (with relay control).


An Analog Door Box (P/N 922450) can connect to an available Door Box port on a 2PGDAD Module. Each module supports up to two Analog Door Boxes, with the maximum number of Analog Door Boxes installed limited only by the availability of 16ESIU station ports to connect additional 2PGDAD Modules.

Any keyset extension that receives Door Box chimes or ringing can control a control relay, which in turn typically enables an electric strike on an entrance door next to the Door Box. Each of the two Door Box circuits in the 2PGDAD Module has an associated control relay that is automatically assigned. There is no separate relay programming required.

The door strike must be compatible with the following 2PGDAD Module relay specifications:
Table 1. 2PGDAD Module Relay Contact Specifications
Contact Configuration: Normally open
Maximum Load: 500 mA @ 24 VDC, 250 mA @ 120 VAC

Connecting an Analog Door Box to a 2PGDAD Module

Preparing the 2PGDAD Module

  1. Following the instructions in your system's Hardware Manual, remove the 2PGDAD module cover and cable knockout.
  2. Do not connect the 2PGDAD to a 16ESIU port. This will come later.

Wiring the Connecting Blocks

  1. Position the 2PGDAD Module so the cable knockout is facing towards you.
  2. The 2PGDAD Module has two connecting blocks just above the cable knockout.
    • The block on the right is the Door Box Block.
      • Terminal 1 is at the bottom of the block.
      • Terminals 2 and 3 are for Door Box 1. Be sure to skip terminal 1.
      • Terminals 4 and 5 are for Door Box 2.
    • The block on the left is the Relay Block.
      • Terminal 1 is at the top of the block.
      • Terminals 1 and 2 are for Relay 1.
        • If you dial the extension number for Analog Door Box 1 and press [Open Door] [Open], Relay 1 will close.
      • Terminals 3 and 4 are for Relay 2.
        • If you dial the extension number for Analog Door Box 2 and press [Open Door] [Open], Relay 2 will close.
  3. The following drawing shows the completed wiring for both Analog Door Boxes with relay control.

Setting the 2PGDAD Module Jumpers

The jumpers to the right of the Connecting Blocks set the function of the 2PGDAD Module. When you are done wiring the 2PGDAD Module, be sure the jumpers are set correctly.

  1. Since you are setting up Door Boxes, be sure the jumpers are open. See the illustration below.

  2. Do not connect the 2PGDAD to a 16ESIU port. You will do this after you program the 2PGDAD Module.
  3. Go to PGDAD Programming Basicsto assign the 2PGDAD Module primary and secondary ports.
  4. Go to Programming Analog Door Boxesfor additional Door Box programming.
  5. There is no programming required to assign or activate the 2PGDAD Module relays.
