Aiphone JBW-M User manual

- INSTRUCTIONS -
The JBW-M adaptor converts a standard CCTV camera's signal to a 2-wire signal, compatible with the JF and JB
Open Voice Color Video systems. This allows the utilization of a color CCTV camera and a separate audio door
station (JF-D or JA-D) to be used in place of a JF/JB 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.

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/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 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.

equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to
try and correct the interference by one or more of the following measures:
— Reorient or locate the receiving antenna.
— Increase the separation between the equipment and receiver.

Only information pertaining to the connection and operation of the JBW-M and devices interfacing
with it are included here. For complete installation, wiring, and operational information about the
JF-2MED or JB-2MD system, please refer to the Installation Manual included with the system.
SPECIFICATIONS:
Power: Supplied by JF/JB Monitor
Video Input & Output: Composite 1V Peak-to-Peak, NTSC
Connector: BNC
Audio Door input: Use JF-D/JA-D surface mount door station only
Relay: Normally open output, 24VDC, 1Amp
Wire: 18AWG, 2-conductor, non-shielded, solid or stranded
Wiring distance: Max. 330' from JBW-M to Monitor
Dimensions: 1-5/8"H x 7"W x 4"D
OPERATIONS (CONT):
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/JA-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.
