Aiphone MKW-M Switch User Manual


 
OPERATIONS
Activation of the camera from a Monitor:
1. The CCTV camera can be viewed on any of the MK 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 2-1/2 minutes.
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 and audio will stay on for approximately 45 seconds if not
answered.
2. Pick up the handset to answer, and hang up to conclude. The monitor will turn off when the handset is 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. 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 (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
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.
