glass break question and event 1146 on elk??

[pjwinstalls]

I had a wireless glass break trigger my alarm last night but there was no glass break... arent false alarms on glass breaks rare??

When there is a burglar alarm, it will show event 1003 in the log stating burglar alarm, then at the same time will have event 1146.....why is this?

Thanks!

I've never had one trip unless there was some sound to make it trip. A ziplock filled with Legos sets mine off every time.

Could a bird have hit the window? Usually the shatter sound is what causes it go off, or a thud followed by a shatter. Some of them monitor air pressure changes also to reduce false positives.

They are cheap, I would just replace it.
