- 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.
