Aiphone KCW-D/B User manual

- INSTRUCTIONS -
The KCW-D/B adaptor converts the 2-wire video signal from the KC, GF, JA, JB, 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.

TO POWER THE CAMERA:
(1) WHEN IN USE
- Install a switch or relay contact in series with the "+" terminal from the power supply (see diagram).
- Solder a jumper between points labeled AA & BB on the KCW-D/B main PC board (see illustration).
This allows the camera to be activated manually, or when relay contact is activated.
(2) CONTINUALLY
- Solder a jumper between points labeled AA & BB on the KCW-D/B main PC board (see illustration).
This will provide continuous power to the camera, which may cause the camera to be warm.
Note: Continually powered, the overall life of the camera will be reduced and condensation may occur.

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. 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, including those being connected
to GF-4Z, GF-1MD or GF-1MDK.
3. The KCW-D/B can also be connected to a GF-4Z. Wire to an output as above, but make sure additional
wires are run to the KCW-D/B for power. Pg. 2

KCW-D/B for Composite Video Output from MK-1GD, MK-2MCD, JA-2MCD, JB-2MD Monitors
The JA, JB, and MK 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 JB 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/JB
product instructions for further details about the built-in video output connection. If using the
KCW-D/B with these monitors, connect as shown above.

OPERATIONS
Using the KCW-D/B for VIDEO OUTPUT with the KC, GF, JA, JB, and MK systems:
1. When a call is initiated from the door station (KC, JA, JB, MK) 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/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 input or go
through the proper modulator.
NOTES:
KC, JA, JB, 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 System 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.)
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/B.This application
will shorten the life of the camera.
