I want to put a fire alarm in my daughter's room. However! They go off for not reason! Properly go off, not the beeping because it needs new batteries. We've just taken another one down because it kept going off. Why?
This is the third brand new alarm we've tried and the second time we've tried one from another room. They all work in other rooms. We've done the waving a match under them.
They go off in the middle of the night when everyone is asleep. They'll also go off in the middle of the day when I'm at home alone with the door open. I've just realised that we've never come home to them going off though.
They are normal fire alarms, not carbon monoxide detectors. Plus there is nothing that would cause that in her room.
She/we don't smoke/vape. I would smell it. Plus they go off when I'm alone or we've all been downstairs for hours.
No candles or steamer things.
Various different places on her ceiling.
Different brands.
Nothing outside.
Nothing that would give off heat or smoke.
No evidence of pests (no idea what they wood do anyway)
The fire alarm just outside her bedroom door is fine.
Her room is always inexplicable warm even without radiators. Not hot but it's consistently warmer than the rest of the house. 2 of her walls are external walls, one is made of plaster board and wood with an empty space above the stairs next to it and the other is a thick wall next to our bedroom. Shes north facing. There are no pipes under her room. Her room is above the dining room so no heat from there. It's the same size as our room.
We've had to pull the dining room ceiling down in the past so we know there is nothing under her floor. We also built the plaster board wall so again, know there is nothing in there. We also had the attic boarded so we know there is nothing in the ceiling.
Any ideas? The warm room is good if inexplicable. The fire alarm is an absolute pain.
