Just realized why those glass break sensors keep going off in the warehouse I service

I was out at this big distribution center near Columbus last week, they got these huge open bay areas with metal shelving everywhere. Kept getting false alarms on the glass break sensors, like 3 times in one week. Company was getting pissed, thought I messed up the install. So I stayed late one night to watch what was happening, and it turns out the forklift drivers were dropping pallets onto the concrete floor. The vibration from the impact was setting off the sensors through the walls, not even breaking any glass. I tested the sensitivity settings and they were at default, but this place has concrete block walls with no insulation, so every little thump travels. Ended up moving all the sensors deeper into the aisles and adjusting the pulse count higher. Has anyone else run into this with big industrial spaces where the building itself is the problem?

Didn't someone post on here that concrete block walls basically act like giant drums for vibrations? Sounds like that's exactly what's happening with those pallet drops.

Wait, so concrete blocks are basically giant floor toms for forklifts now? That's hilarious and also kind of terrifying if you're trying to sleep next to a warehouse. Guess the pallet drops are just the drummer warming up for the next shift.
