When I Bar-b-q and have the windows open if the wind is blowing right the smoke detector goes off. One time I heard it go off and went in to shout it down and couldn’t find my sons… My four year old had gotten his 2 year old brother and led him out the front door to stand in our “family fire gathering spot”
I would rather have it be an annoyance and go off then like someone else stated not go off.
Plus… would you sue a company if it did go off and there was no fire or would you sue if it didnt go off and someone loss their life…
That is a major factor controlling the sensitivity.
