DESCRIPTION
A Doorphone Controller (DAC-1Z) can be connected to your MERLIN Plus
system to allow employees to answer calls made from a business entrance.
The controller is connected directly to a CO line port on the MERLIN PLUS
control unit. Callers using the doorhone can press a button at the building
entrance to ring a telephone in your MERLIN Plus system. An auxiliary alert
device (such as a doorbell, chime, or tone generator) can be connected to the
Doorphone Controller so that it will ring when the doorphone button is pushed.
An optional electric strikeplate release can be obtained for door operation to
permit the caller to unlock the door by entering a preset code on the doorphone
keypad. The electric strikeplate can also provide an alarm that sounds when the
door is opened by unauthorized means or is not closed within a certain
amount of time.
