40 Multivision® Pro Installation and Operation Manual
Tape Mode Live Alarm
Response
When a mechanical and/or motion alarm occurs in the tape
mode, the multiplexer processes the event in the background.
If two VCRs are connected, it records the alarm event on
videotape but does not indicate the alarm to the user. This
allows alarm recording during tape playback. See Simultaneous
Record and Play.
When the multiplexer detects the initial live alarm in tape
mode, it does the following:
1. Toggles the alarm relay.
2. Activates the alarm output (motion alarms only unless
PASS-THRU EXTRNL ALRMS is YES).
3. Switches to the VCR ALARM RECORD TIME encoding
rate.
4. Encodes the camera as “alarm” and sends it to the VCR
on a priority basis.
The multiplexer remains in the alarm state until ALL of the
following occur:
• All mechanical alarms are released.
• No motion detected at cameras set for motion alarms.
• The ALARM DURATION time elapses.
• The alarm hold input is released.
Multiple alarms are processed in the order they occur.
