[Hai-users] Sensor question

[Mike Nolan]

We have an interesting intermittent issue with our Aegis 3000.  

There is a zone on it that is a garage overhead door sensor, using 
a magnetic switch.

Sometimes it notes a change in status when the garage door is raised or
lowered, sometimes it does not.  On a few occasions I've seen a report 
of a trouble with that zone.

Is this most likely a bad switch?
