About the Doorphone
What is the Doorphone?
The Doorphone connects to a digital Meridian Norstar™ telephone port to provide
call notification and handsfree communication from a premise entry location to other
stations on the system.
Door opening functionality can be achieved if installed with one of two optional
hardware devices. If an External Relay Module (ERM) is installed, the call will be
ended immediately after the door is opened. If a Door Opening Controller (DOC) is
installed, the call will continue until
QUIT
or
®
is pressed.
