Old timer at the supply house swore by foam backer rod for everything
Met this retired installer, must have been 70, at the counter in Albuquerque last Tuesday. He told me I was wasting time with my usual silicone pack and that foam backer rod would stop false alarms on glass break sensors. I tried it on a tricky job with a bank's front window that kept triggering at night. Has anyone else had good luck with that stuff or is it just a band-aid for bad sensor placement?

Nah that stuff works. I've used it on a few finicky sensors and it killed the false triggers every time.

That "killed the false triggers" line reminds me, @morgan.cameron ever spray that stuff on a smoke detector by accident?
