Pnt (Point) Alarm point number.
Description User-definable description for the discrete alarm input.
Rev (Reverse)
Reverse: Check this box to reverse the polarity of the alarm point. Left un-checked,
this means a normally-open contact closure is a clear condition. When polarity is
reversed, a normally-closed alarm point is clear when closed.
Example : Door with a magnetic door sensor. When the door is closed, the magnetic
sensor acts like a closed relay. However, you know this should not trigger an alarm
condition. This means you'd want the door alarm reversed in the NetGuardian
because we are looking for a normally closed condition.
Notification devices
Check which notification device(s), 1 through 8, you want to send alarm notifications
for that alarm point. These notification devices correlate to one of the 8 devices you
setup for notification (email, SNMP trap, etc.) Check the box in the green bar (top) to
have a notification device send an alarm for all alarm points.
