DBM21 Connection to Door-Phone System
Terminate the RJ-25 (RJ-11 6 conductor) connection as in the chart above on both ends.
Connect the DBM 21 to a standard 3-way phone splitter. Connect the door-phone station,
the Panasonic phone system and the DBM21 to the splitter.
Door-Phone Camera Connection to W.H.E.N. System
The camera can be located inside the door-phone station (optional on Panasonic and Channel Vision models)
or can be a standard security camera located near the front door. The DBM21 will supply power for the internal
camera in the door station (if equipped). Using standard coaxial (RG-6 or RG-59) cables connect the output of
the camera to an input on the AVH21. In the AVR21EN camera setup, be sure to assign the camera input used
to the appropriate DBM21.
AVR21EN Setup
Please see the AVR21EN installation manual for details. The AVR21EN can control how the doorbell chimes are
played through each zone, how the zones can interact with the door-phone station and if a security camera is
associated with a door-phone station.
Assign Doors and Cameras
To access the door setup go to the on-screen menu of the AVR21EN. From the main menu, select Zone Setup,
and then select Assign Services. From the Assign Services menu select the Door Setup menu. Select the doors
that are in use and the cameras (if any) assigned to them.
Name Doors
From Zone Setup Page 1, select Name Doors. All doors in the system can be renamed.
Door Ring
From Zone Setup Page 2, select Setup By Number Page 2 and enable or disable door bell chimes for each
zone. The default is for all zones to ring always.
Door Answer
From Zone Setup Page 2, select Setup By Number page 2 and enable or disable door bell answer for each
zone. This will allow or block specific keypads from talking to the door station. The default is for all zones to
answer all doors.
Door Open
From Zone Setup page 2, select Setup By Number page 3 and enable or disable door bell open for each zone.
This will allow or block specific keypads from opening the door locks if the system is using the electronic door
locks on the AVH21. The default is for all zones to open all doors.
