Live Mode Alarm Response
When a mechanical and/or motion alarm occurs in the live mode,
the multiplexer alerts the operator and performs tasks required to
record the alarm event on videotape.
When it detects the initial alarm in live mode, the multiplexer does
the following:
1. Flashes the associated Camera (116) light.
2. Sounds the audible alarm (if ON in setup menu).
3. Toggles the alarm relay.
4. Activates the alarm output (only motion alarms unless PASS-
THRU EXTRNL ALRMS is YES).
5. Displays the alarm camera on the call monitor, overlaid with
the ALARM message.
6. Switches the main monitor to the highest multicamera format
if the alarm camera is not already on display (unless the ALARM
MESSAGE DISPLAY option is set to OFF).
7. Overlays the alarm camera on the main monitor with the
ALARM message (unless the ALARM MESSAGE DISPLAY option
is set to OFF).
8. Switches to the VCR ALARM RECORD TIME encoding rate.
9. 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 contact alarms are released.
No motion is detected at cameras set for motion alarm.
The ALARM DURATION time elapses.
The alarm hold input is released.
Multiple alarms are processed in the order they occur.
