Aiphone KCW-D/B Instruction Manual
0408
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.Since the video signal is common throughout the system, video will be present from the KCW-D/B when
any GF-1MDK or GH-1KD monitor is on.
2. Any 24V DC, 1A power supply can be used to power the KCW-D/B (Aiphone PS-2410A or other).
Method 2: Connecting KCW-D/B directly to GF-VBC / GH-VBC video bus control unit

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.
