Notes:
1.Since the video signal is common throughout the system, video will be present from the KCW-D/B when
any GF-1MDK monitor is on.
2. Any 24V DC, 1A power supply can be used to power the KCW-D/B (Aiphone PS-2410A or other).

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.
