Aiphone KCW-M User Manual

Video Modulator with Audio Door Station and CCTV Interface

- INSTRUCTIONS -

The KCW-M adaptor converts a standard CCTV camera's signal to a 2-wire signal, compatible with the KC 1x3
Color Video system. This allows the utilization of a color CCTV camera and a separate audio door station (JA-D)
to be used in place of a KC-DAR video door station. The CCTV camera can also be connected to a standard
CCTV system for continual viewing and/or recording. The unit is equipped with a relay output to trigger an
external device, such as a DVR or video switcher whenever the audio and video to the Aiphone monitor is on.

OPERATIONS

Activation of the camera from a Monitor:

1. The CCTV camera can be viewed on any of the KC monitors in the system by pressing the MONITOR button.
When the video is activated, the audio door station will be activated to transmit audio to the monitor station. To
initiate 2-way audio with the outdoor location, pick up the handset and speak. When the handset is hung up, audio
and video will turn off.

2. To turn the monitor off, press the MONITOR button again. Otherwise, it will automatically time out after
approximately 30 seconds.

Activation of a camera by the Audio Door Station:

1. When the call button is pressed on the JA-D door station, the monitor will turn on with the image from the CCTV
camera, and the chime will sound. The monitor will stay on for approximately 30 seconds if not answered.

2. Pick up the handset to answer, and hang up to conclude. Conversation will automatically turn off in approximately
2-1/2 minutes if handset is not hung up.

Interfacing Video with Other Systems:

1. VIDEO OUT connection simply passes the composite video signal on to a standard CCTV system, such as a
monitor, input on a switcher, or DVR. This video signal is live as long as the camera is powered. When using this
feature, set the 75 OHM switch to the OFF position.

2. RELAY connection provides a normally open contact closure that can be connected to an external system. This
contact will be closed whenever the Aiphone system is turned on. This can be wired into a record input on a DVR or
any other external device that needs to be notified when the video and audio is activated to the Aiphone monitor.
