Description

The ATU-8/ARU-8 devices will transmit contact relay control and alarm signals over any analog video link. The signal is encoded in the vertical interval of the video, so it will pass through all video equipment. This equipment will work in either directions or both directions at the same time.

Contact closures on the ATU-8 input will be repeated as contact closures at the ARU-8 output. This system uses one active vertical interval line to transmit the contact information and it is field programmable from lines 20 to 25.

The ATU-8 ALARM TRANSMITTING UNIT and the ARU-8 ALARM RECEIVING UNIT together make up an 8 channel alarm and control system. The transmitter inserts the contact information onto the video signal and it will be recorded as part of the video signal so contact information can be retrived apon playback.

A system alarm contact will operate upon loss of power to either terminal or loss of transmission path (video link failure). An internal video sync generator takes over and maintains continuous alarm system operation in the event of video signal failure.
