Aiphone JBWM Instructions User Manual

							- INSTRUCTIONS -
The JBW-M adaptor converts a standard CCTV cameras 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.

							NOTE: This equipment has been tested and found to comply with the limits for a 
Class B digital device , pursuant to Part 15 of the FCC Rules.  These limits are 
designed to provide reasonable protection against harmful interference in a 
residential installation. This equipment generates, uses, and can radiate radio 
frequency energy and, if not installed and used in accordance with the instructions, 
may cause harmful interference to radio communications.  However, there is no 
guarantee that interference will not occur in a particular installation.  If this 
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.
— Connect the equipment into an outlet on a circuit different from that to
     which the receiver is connected.
— Consult the dealer or an experienced radio/TV technician for help.

Note:
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: 1-5/8H x 7W x 4D
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.
