Kate did the fire service fit them ?
we had 2 10 year ones fitted by the fire service but where far to sensitive ours are on the stairs one at the top one at the bottom the bottom one would go off at the slightest thing even a pan of boiling water set it off.
after 4 years the one at the top of the stairs gave up and started chirping these where 10 year batteries but they cant be changed.
i phoned the fire service who arranged to call and have a look when they got here they said about 4 years ago they had a faulty batch of smoke alarms and these where 2 of them .
they then fitted 2 more smoke alarms that detect smoke in a different way so don't go off unless it is an emergency
the only thing is they left the old ones in place as well so i now have 3 working smoke alarms the faulty one i had to cut the wire to stop it chirping if i took them down there would be holes in the plaster.
give the fire service a call its free and they will fit the new ones for you.
Advantages
1) you get new smoke alarms free
2) you get a free dvd about fire saftey
3) you get to see firemen in uniform
