KC, GF, JA, JB, MK & MY Series Video Systems
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.
