APPENDIX B
ALARM RECORDING CONTROL
Uncontrolled Alarm Recording
Most MUX-1602C installations require that alarm events be
documented
on videotape. The MUX-1602C provides all of the
necessary connectors
and signals to accomplish this and is
flexible enough to satisfy
most video documentation
requirements.
An MUX-1602C alarm event begins when the unit detects an alarm
signal
at the
alarm connector. The sequence of events following
alarm
detection is determined by one or more of the following:
•
MUX-1602C option settings.
•
VCR programming.
•
MUX-1602C to VCR interconnections.
The following paragraphs describe how to configure an MUX-
1602C
installation for either uncontrolled or controlled alarm
recording.
When alarm recording is not controlled, the VCR records alarmed
cameras as normal video. Recorder operation is not affected by
alarm events. The VCR simply records alarm video output by the
MUX-1602C at the set time-lapse speed. Uncontrolled alarm
recording
requires only video connections between the MUX-
1602C and the VCR.
Alarm connections are not required.
To set up the system for uncontrolled alarm recording:
1.
Connect the MUX-1602C
vcr in and
vcr out connectors to the
VCR’s video output and video input respectively.
2.
Set the MUX-1602C Alarm Duration option to the
number of
seconds you wish each alarm event to be recorded.
3.
Set the VCR’s time-lapse speed as desired.
4.
Set the MUX-1602C VCR Record Time and VCR Alarm Record
Time options to match the speed set at the VCR.
