My tenant says that the smoke alarm in the hall goes off when she has a shower and that the one in the kitchen goes off when she fries things.
The alarms are mains interlinked and about 6 years old, this hasn't been a problem before.
She is the sensible type but I don't want to replace them only to find that the problem still exists.
I'm busy reading past posts on smoke alarm problems/different types etc but thought that I would post this in the meantime, maybe save some time.
Thanks in advance.
Well if anything I've found quite the opposite. I think the ones based on a
radioactive isotope lose sensitivity, but not other types. I do not know
whether a component in the circuit could drift and make the threshold lower.
I guess its possible. Mine has always gone off if I cremate the toast a bit
too much, but the main variable seems to be draught, ie, if there is one
past the alarm to an open window, for example, then its more likely to go
This newsgroup posting comes to you directly from...
These are both scenarios which will trigger both radioactive and optical
You generally wouldn't fit one of these in a kitchen, but you would fit
a temperature triggered alarm, either an absolute temperature trigger
or a rate of temperature rise alarm.
For the shower, this means steam is getting out into the hall. Is there
an extractor fan in the shower room and does it work? Excess moisture
getting out into the rest of the house on a regular basis might have
other effects too, such as mold forming in cold spots.
Also for the kitchen, is there an extractor hood over the hob, and does
it work? When were the filters last cleaned or changed? A functioning
cooker hood will reduce the amount of air-borne fat when frying, which
will reduce chance of smoke detector going off and reduce the grease
which forms on all surfaces/decorations.

yes, so they're probably battery powered & thus probably ioninsation ones.
In which case they're very touchy, and the solution is to move them a bit f
urther away from the smoke/steam until they no longer false alarm. This inf
o was on the wiki before it got deleted.

So wouldn't it be better to have a heat detector in teh kitchen rather than a smoke detector.
What is the problem of granny putting a tea cosy on the hob ?
Surely that is what needs avoiding rather than waiting for the cosy to catch fire and produce smoke so it triggers a smoke detector.
If this happened every week wouldn;t it be better finding another solution ?
But don't forget that where you place them is important too.
What makes sense is irrelevant to what is buyable currently, fuckwit.
Easier said than done with those with dementia, stupid.
Corse it can when it makes it obvious to others in
the house that the silly cow has just done it again
and stops the cosy from setting fire to the house.
That sort of forgetfulness doesn’t
happen every time they make a cuppa.
Yes, but she normally would turn the hob
off when taking the kettle off it, fuckwit.
Wrong, as always.
Because the only way to do that would be to
physically remove the kettle that goes on the
hob and even if that is done, she'd just buy
another next time she goes shopping, stupid.
Thanks for that completely superfluous proof
of why you only ever get to clean the dunnys.

Heat & rate of rise detectors alert much later than ionisation & optical. Ionisation & optical detect fires before they begin but are prone to false alarms. If you position the latter correctly they don't false alarm - that's the best option.
