Last week, at home with the family with my alarm system armed in stay mode, the alarm started going off due to a glass break in my sun room.
I went to take a look to see what was going on, only to find the alarm had been triggered when my kids accidentally dumped a container of pretzels on the floor. One of these types of plastic barrel containers.
I thought they'd at least dropped a glass or something to cause it to alarm, but no, just the barrel and pretzels falling on the floor. Has anyone else seen glass break detectors alarm on very odd (not glass at all) things?
