I/O ALARM
: Each channel corresponds to an I/O status (see the following status explanations),
which means that when an alarm is triggered, it will activate the corresponding channel to start
alarm recording.
I/O status types:
N.O.:
“Normally open”: It means that in its normal state, the sensor is kept under constant low
voltage. If the sensor voltage changes from low to high, then the alarm will be triggered.
N.C.:
“Normally closed” (also referred to as “normally connected”): The normal state of the
sensor is under constant high voltage. If the sensor voltage changes from high to low, then the
alarm will be triggered.
OFF:
Set the I/O to “Off” if external sensor alarms are not in use.
