Video Demodulator for the

KC, GF, GH, JA, JF, MK & MY Series Video Systems

- INSTRUCTIONS -

The KCW-D/B adaptor converts the 2-wire video signal from the KC, GF,GH, JA, JF, MK & MY systems
to a standard composite video output signal. This allows the image from the door station to be seen on a
standard CCTV monitor or TV (video input). The video image can also be recorded if connected into a
VCR, DVR, or other recording device.

Notes:

1. Video will be present from the KCW-D/B when any entrance panel is on, broadcasting video through all
of the outputs of the GF-VBC/A or GH-VBC. The KCW-D/B can be connected to any unused output.

2. KCW-D/B can be connected to any of the six outputs on the GF-VBC/A or GH-VBC, including those
being connected to GF-4Z, GF-1MD, GF-1MDK, GH-4Z, or GH-1KD.

3. The KCW-D/B can also be connected to a GF-4Z or GH-4Z. Wire to an output as above, but make sure
additional wires are run to the KCW-D/B for power.

KCW-D/B for Composite Video Output from MK-1GD, MK-2MCD, JA-2MCD, JF-2MED Monitors

The MK, JA and JF-2MED series monitors include built-in video output as a standard feature.
The connector to access that output is provided with each of the JA and JF master monitors.
The connector for the MK series (Part #238150) is not included with the product, but can be
ordered separately.

While the KCW-D/B adapter will work as a video output device with these monitors, it is
recommended to use the built-in video output whenever possible. Refer to the MK/JA/JF
product instructions for further details about the built-in video output connection. If using the
KCW-D/B with these monitors, connect as shown on page 1.

Note: When using the built-in video output, video is present only when the master
monitor is in use. If you require video to be present at the output when any monitor in
the system is used, the KCW-D/B adaptor would be required.

Video Output Control:

Using a small screwdriver, adjust the Video Output Control to obtain the correct level for the CCTV device
you are using. The Video Output Control is located under the rubber cover on the upper right hand corner of
the KCW-D/B faceplate.

OPERATIONS:

Using the KCW-D/B for VIDEO OUTPUT with the KC, GF, GH, JA, JF, and MK systems:

1. When a call is initiated from the door station (KC, JA, JF, MK) or entry panel (GF, GH), the monitor called
will ring and the picture will activate. At that time, the video signal out of the KCW-D/B 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, DVR, 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 inpu t or go
through the proper modulator.

NOTES:
KC, JA, JF, MK systems only: When the MONITOR button on any monitor is pressed, the video will turn on

for approximately 30 seconds to 2-½ minutes (depending on system), and video signal will be sent to the
monitor via the KCW-D/B.

GF, GH Systems Only: Video is present at the KCW-D/B 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.)

The KCW-D/B adaptor can be used to integrate a KC or MK video door station with a standard CCTV monitor
or DVR system. Modification is required. Contact Technical Support ([e-mail]) and request
the modification information.
