Connecting Door Speaker, Door Button, and Door Ajar Switch to the AT&T Door Phone Controller
Polarity of wires is not important.
Total wire length should not exceed 1500 feet.
Door Ajar switch should be closed when door is closed. If a door ajar switch will not be used, you must leave a jumper installed across the two “Door Ajar Switch” terminals.
Use the diagram in Figure 2-4and follow the steps below:
1.Run shielded twisted pair wires (22–24AWG) from the “Speaker” terminals on the rear panel of the AT&T Door Phone Controller (13 & 14) to the installed Door Speaker (1 & 2). Connect the shield to the “Shield” ter- minal on the controller (12).
2.Run 2 wires (22–24AWG) from the “Door Bell Button” terminals (10 & 11) to the door bell push button on the installed door speaker/push button assembly (3 & 4).
3.Run 2 wires (22-24AWG) from the optional “Door Ajar Switch” terminals (8 & 9) to the installed door ajar switch.
Remote Door Open Switch (optional)
A remote door open switch (normally-open contact) provides additional means for opening an electric door opening device. To connect wires for a remote door open switch use the diagram in Figure 2-5and follow the steps below.
1.Install the remote door open button in desired location using manufacturer’s installation instructions.
2.Run 2 wires (22–24AWG) from the installed (normally- open contact) remote door open switch to the “Remote Door Open” terminals (6 & 7) on the AT&T Door Phone Controller back panel (polarity of wires is not important).
