Chapter 6 — Alarms 39
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 (1–16) 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.
