Where I used to work we had an FM200 system that I was always super-careful around. If I even thought there was a chance I could set it off I would disconnect the firing pin then leave my car keys there so I couldn’t leave without re-connecting it. They company that installed it said the sensors are looking for “fine particulate matter” so even things like drywall dust could set it off.
