NOTE: One or the other will apply, not both.

3.Verify all connections when connecting the door strike contacts on the AT&T Door Phone Controller to existing door open buttons. Make sure of the following:

■The NO and C contacts are connected in parallel to a normally-open button.

■The NC and C contacts are connected in series to a normally-closed button.

Auxiliary Alert Device (optional)

If the Auxiliary Alert Device has more than a 1 Amp draw, then an external relay arrangement will be required.

See Appendix E for specific auxiliary alert device installation information.

In most configurations, the Door Phone Controller will cause a telephone to ring when the doorbell button is pushed. An aux- iliary alert device (chime, bell, horn, tone generator, etc.) can also be used as an alert to notify the person inside the building that the doorbell button has been pushed (Auxiliary Alert Mode). A low-voltage device (24V or less) is recommended. Follow the steps below (refer to Figure 2-7)for wiring auxiliary alert device (door bell/chime) to the Door Phone Controller:

1.Install the auxiliary alert device (door bell/chime) as in- structed by the manufacturer’s installation manual.

2.The Normally Open (N.O.) and Common (C.) relay con- tact, located on the Door Phone Controller back panel (see Figure 2-7),are accessible at the Door Phone Con- troller terminal block. Wire these to the auxiliary alert device and it’s power source as instructed by the manufacturer’s installation manual.

Connecting Power

When the Door Phone Controller has been mounted to a wall or placed on a shelf and all cables and wires have been connected to the back panel, plug the transformer into a 120 VAC outlet. See Figure 2-8.
