Do smoke alarms get more sensitive as they get older? Mine is about 18 years
old. It still works in fact I just put a new battery in it a month ago.

My wife has a steam generator iron and if she does not open all the windows
in the room she is using it the alarm will go off, most annoying as she has
stopped ironing now. At least I'll get a cup of coffee.The alarm is in the
hall, not where she is ironing, but we have a vent above the door which does
not help.

It is pouring with rain just now and the humidity is quite high so I think
because of that and also the high temperature that is what is making it go
off.

When I think about it the alarm seems to go off more now than it did before.

Anyway I would buy a new alarm but if the new one is going to go off when
there is steam instead of smoke there is no point. So is there a specific
type of smoke alarm that is less sensitive to steam or all they all
basically the same?
