Operation – Basic Door Answer Function
Visitor Presses Door Speaker Button
When a visitor presses the door speaker push button, the
AT&T Door Phone Controller will signal the telephone
equipment inside your home or building to ring, and activate a
door-bell/chime device (optional). Any additional presses on the
door speaker push button will be ignored until the option
selected ring/chime duration has expired (with the exception
that a confirmation tone will still be sent to the speaker when
the door button is pressed).
Answering a Call from the Door Speaker
The person inside the building can simply answer the ringing
phone and establish two-way communications with the door
speaker. To open the door, the person inside the building either
enters the Door Code on the telephone’s keypad or presses
the customer provided door-unlock push button. Either of these
actions will activate the customer provided electric door strike
plate device.
