AT&T Door Phone Controller Location
You need to determine exactly where you want the unit
installed and how you want it configured. Another consideration
is what components will be used with the AT&T Door Phone
Controller. Here are some questions that must be answered
prior to installation:
■ Do you currently have a door speaker installed?
■ Do you have a business telephone system (PBX or EKTS)?
■ Do you have a remote door unlock mechanism (electric
door strike) installed?
■ Do you have an auxiliary alert system (door chime) currently
installed?
■ Do you have a door ajar switch installed?
The AT&T Door Phone Controller is designed to control the
functions of the components mentioned above, and how you
answer these questions will determine how the AT&T Door
Phone Controller will be installed, optioned, and operated.
When selecting options for your AT&T Door Phone Controller,
e.g., to change the door-unlock security code, the AT&T Door
Phone Controller unit must be DIP switch selected to Option
Selection mode. For this reason you may want to install the
AT&T Door Phone Controller unit in a secure area which has
access only by authorized personnel. If you are installing the
unit in a business environment (currently have PBX/EKTS), you
may wish to install the unit along with the telephone equipment.
(See Figure 2-2 for a typical installation diagram.)
