Last night one of our glass break sensors started doing this extremely loud high pitched squeal, for 10 seconds every minute or so. After I got my heart rate back down to normal, I deactivated the system, it shut up, everyone was happy.
So with the alarm deactivated, about 2 hours later this thing starts doing it again. Does anyone have any idea what the heck would cause that? I was thinking maybe the sensor had died or had its connection cut and that was why it was going insane but I truthfully have no idea.
