32 Simplex Multiplexer
Record Mode Alarm
Response
When a mechanical alarm occurs in record mode, the Simplex
alerts the operator and performs tasks required to record the
alarm event on videotape.
When the initial alarm is detected in record mode:
1. The associated CAMERA LED flashes.
2. The alarm relay is energized.
3. The monitors display a full-screen image of the camera
associated with the alarm. With multiple alarms, full-screen
images sequence at the current dwell rate on both monitors.
4. The camera image is overlaid with an ALARM graphic on
the main monitor (if ALARM MESSAGE DISPLAY is ON).
5. The alarm record encoding rate is selected.
6. In REC ALL mode or REC QUAD mode, the camera image
is encoded as alarm and output to the VCR on a priority
basis.
7. When the Simplex is in one camera record mode, it switches
to the alarm record encoding rate and sends images from
the camera associated with the alarm on a priority basis
along with images from the camera selected in one camera
record mode.
The Simplex processes multiple alarms in the order they occur.
All alarms are identified by flashing CAMERA button LEDs
and receive priority for output to the VCR.
The Simplex remains in the alarm state until ALL of the fol-
lowing occur:
• All mechanical alarms are released.
• The ALARM DURATION time elapses.
• The Alarm Hold Input is released.
Once the Simplex exits the alarm state, it returns to the previ-
ous display and record mode.
