Video Modulator with Audio Door Station and CCTV Interface

- INSTRUCTIONS -

The JBW-M adaptor converts a standard CCTV camera's signal to a 2-wire signal and is compatible with the JF
Open Voice Color Video system. This allows the utilization of a color CCTV camera and a separate audio door
station (JF-D) to be used in place of a JF video door station. A motion detector or other activation device can be
connected to the Sensor input to trigger the system. 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.

INTERNAL ADJUSTMENT WHEN JF-D AUDIO DOOR STATION IS INCLUDED:

INSTRUCTIONS:

1. Open unit by removing 5 small
screws and lifting off cover.

2. Locate Jumper labeled JP1 on the
right side of the PC board, and JP3
on the top of the board.

3. Remove both jumpers completely,
or move them so they're on just
one of the posts.

4. Replace the cover and the 5
screws.

OPERATIONS

Activation of the camera from a Monitor:

1. The CCTV camera can be viewed on any of the JF monitors in the system by pressing the MONITOR button.
This will turn on the video, but not the audio. To initiate 2-way audio with the outdoor location, press and release
the TALK button momentarily.

2. To turn the monitor off, press the MONITOR button again. Otherwise, it will automatically time out after
approximately 1 minute.

Activation of a camera by the Audio Door Station:

1. When the call button is pressed on the JF-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 approximately 30 seconds unless answered.

2. Press TALK momentarily to answer, then speak hands free. Press TALK again to conclude, or unit will turn off
automatically in approximately 1 minute.

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. SENSOR input allows a motion detector or other activation device to remotely turn on the camera. Use any device

with a Normally Closed contact. If an audio door station (JF-D) is included, the sensor input cannot be used.

3. RELAY connection provides a normally open contact closure that can be connected to an external system. 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.
