Oh, yeah. That. Well, your el-super-cheapy smoke alarms only test for particulate matter, so they give a lot of false negatives and miss a lot of fires, so it's hard to find them in the US. The low-grade ones available here just test for carbon, so that way they're going off if there's a lot of carbon dioxide, carbon monoxide or carbon particles. Not going to find vape.
I work in a high-security room with an instant isolation system and a halon-dump that costs $37,000 to reload (we found that out when someone tried to sneak a cigarette in here). The fire/smoke detectors actually monitor the nitrogen/hydrogen/oxygen ratio and go off if there's a statistically significant "change in the atmosphere" (of the room, obviously). I didn't set it off when I first started vaping (even though I tried)--and it's been known to go off when one of the air conditioners in here blew a transformer.
But still, trusting me is not a good idea...
