OPERATIONS
Using the KCW-D/A for VIDEO OUTPUT with the KC and GF systems:
1. When a call is initiated from the door station (KC) or entry panel (GF), the monitor called will ring and the picture
will activate. At that time, the video signal out of the KCW-D/A adaptor will be present, and the picture can be
seen on the CCTV monitor(s).
2. The video output can be connected to any receiving device that accepts a composite video signal (75 ohm, 1V
peak-to-peak). This could be a standard CCTV monitor, multiplexer, or an adaptor that modulates the video onto
a cable TV channel. To take the video signal directly into a TV, use a spare video input or go through the proper
modulator.
NOTES:
KC System Only:
When the MONITOR button on any Monitor is pressed, the video will turn on for approximately 30
seconds, and video signal will be sent to the monitor via the KCW-D/A.
GF System Only:
Video is present at the KCW-D/A regardless of which monitor has been called.
Using the Demodulator to integrate a KC-DAR video door station with a standard CCTV monitor:
(No audio communication or Tilt is possible with this application.)
1. To view the camera location at any time, the camera must be powered at all times, or a switch must be installed
to turn it on. To do this, the PC board must be modified by adding a jumper wire in the location indicated on the
wiring diagram on page 1. Soldering is required. This modification should be done by qualified technicians only.
2. There is no Tilt control of the KC-DAR camera in this application.
3. There is no audio communication with the KC-DAR in this application.
4. If the camera is powered continually, there will always be a video output from the KCW-D/A.This application will
shorten the life of the camera.
