Veteran installer told me to stop using screw terminals on glass break sensors
An old timer I met at a supply house in Austin told me to ditch screw terminals on glass breaks and go with soldered connections instead. I thought he was crazy until I had 3 callbacks in 2 months all because vibrations loosened the screws. Has anyone else switched to soldering and noticed fewer false alarms?

Three callbacks in two months is rough, I feel your pain. I just swapped out 12 glass breaks at a local high school here in Phoenix, all screw terminals, and half of them had the same vibration issue you're describing. The thing nobody talks about is the metal fatigue on the actual sensor board trace when those screws wiggle loose and tighten back up over time. I started using a tiny dab of blue Loctite on the screw threads before cinching them down, and it's been night and day for reliability without the hassle of soldering each one.
