How sensitive are smoke detectors?

^^ yeh it varies, soem are super sensitive, some aren't.. And steam works the same as smoke, it'll set some alarms off

if there is enough smoke in the room to set the thing off people will smell it outside anyway. i smoked in dorms many a time and i can tell you most times it went unnoticed, a few times people smelled it, amoke alarms never went off

I still live at my parents, and my room has a smoke detector. It's a pretty small room, too. Only about four people can fit in it comfortably. We toke it up in here so bad sometimes that the room is hazy. It never sets off the smoke alarm, though. We were high one night and decided to try and set it off, so we each took a big hit and blew on it at the same time. No go. After that we thought it might be busted, so I lit a piece of paper and held it about three feet below and it went off instantly. Maybe pot smoke isn't hot enough to set one off? Maybe the bong water cooled it enough? We've used pipes and joints too... maybe stoners invented the smoke detector!

most smoke alarms work on a small amount of decaying radiactive medium. it emits particles which are picked up my a sensor, this allows the circuit to break and so triggers the alarm. normal smoke from a fire is dense and so the circuit is broken. cigarette smoke isn't that dense but cannabis smoke is more so. its likely at your college they aren't that sensitive. they know that people are gonna smoke and so dont want to have em too sensitive.

when i was at uni my smoke alarm wasn't even a smoke alarm, it was a heat alarm. it didnt go off, even when i made a smoke bomb and set it off in my mates room when he was asleep. it did however go off when i held a lighter underneathe it.

upshot. check if it aint a true smoke alarm you got nothin to worry about. becareful if you disconnect it though cus you mite need it if you are smokeing adn then might check.
you could however replace it with a dead battery. that way it willl never go off.

peace

I also have a question about smoke alarms...

Me and my room-mate got a kickass room on the first floor of a dorminatory. It's outside the hall on the outside of the building so I don't have to worry about people smelling it, it just that this room used to be made for handicap people and it is rigged with shower sprinklers in the ceiling so that whenever a fire does occur it will put it out.

So, we already tried taking to down once and about 5 minutes later a security guard knocked on our door and told us there was a stress signal or something coming from this room. Asked if he had been cooking anything or messing with the alarm, we said no. So that is out of the question.

Now my room-mate already blazed a few times in the bathroom but it was just like 2 small bowls, and we have a vent in the bathroom that he blew into. Do vents suck inside air out to the outside? Also, if we just plan on smoking bowls in the bathroom and I tape a walmart bag over the detector do you think we'll be safe? Peace, Love & Happiness. :rastasmoke:

stress signal? or distress?

crazy

go and ask the security guard what causes that to go off (u can say u been cooking or something) and ask him if u can get it changed to a normal smoke alarm.

One of two. I forgot what he exactly said. But basically he knew we were fucking with it.

if its a vent in the kitchen it will pull air out, so like smoke and stuff when cooking. pass it through a filter and then outside. so you should be all good. just depends where the vent is near

the vent is in the bathroom... is there a difference?

We spent nearly every day of both semesters last year roasting in our dorm, and never once did we set off the smoke detector. We had an open window with a fan blowing outwards, and that was it. The only issue was the smell. We made a sploof to fix that. Our room smelled drier-sheet fresh!
