Fire alarms keep going off in an unusually warm room

[Thismightbeouting]

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.

Im confused. Just because I want another alarm does not mean I'm anxious.

I bet that was scary. I'm glad everything was OK.

But surely the fire alarm in hallways and kitchens only date from before we filled our rooms with electronics. The biggest firehazards are often literally right beside our beds now, if a phone charger catches fire in the room I would prefer to know BEFORE the room is ablaze enough to set of the hallway alarm if it were me.

😂 He just doesn't always think when he puts them down. Our kitchen gets bright sun so you can't always see if the hob is on and he has put them on the hob not realising it was on. He's set them alight 3 times (I think). No damage done to anything other than the oven gloves. He now checks the hob more so hopefully it won't happen again.

We also had a fire alarm that was prone to going off for no reason - always waking everybody in the early hours of the morning.

ir was at the top of the stairs.

In the end we removed it and didn’t replace it (we have another one on the same stretch of ceiling further along, that’s fine).

We never did figure it out. It first went off about 2 weeks after we moved in, so it felt extra creepy!

Ours isn’t a warm house. We do back onto woods though, so get a few creepy crawlies.

I did later find out my son (whose room’s closest to it) vapes aswell …

It was my own stupidity (and sleeplessness from a new arrival to the family) but I frequently say the smoke alarm saved our home if not my life - the level of trust I have in them now is significant! It truly was barely smouldering when I got there, and absolutely no harm done, but only because of the Nest Protect (which said out loud “smoke detected on the landing” so I knew exactly what and where the issue was). I genuinely can’t recommend enough.

A warm room isn't going to set off a smoke alarm.

A smoke alarm outside of the door is perfectly adequate.

Nobody has been outwardly hostile towards you yet you're very snippy when people are suggesting your anxiety might the issue here, after you yourself have admitted to having anxiety.

None of my behaviour suggests anxiety. If you read my posts, there is no indication. I literally just acknowledged that it was not necessary but I just want a fire alarm up to make me feel better.

I get so fed up of people on here diagnosing others with anxiety. It undermines what anxiety actually is.

Actually, I've just remembered something. Years ago a housemate had a crystal in her bedroom window and a teddy bear on her bed caught fire. Properly, not just smouldering. It didn't set off the alarm that was a few feet away in the hall.
She happened to be upstairs in the bathroom and smelt it so all was OK. It had just started on her pillow though so wouldn't have been much longer before it would have been a 999 job.
The (reputable) landlord tested and said the fire alarm was fine. I can't remember if her door was shut.

I refuse to have crystals in our windows. That's common sense.

can you install an air purifier in that room? Also, open the windows wide and air the room in the daytime as much as possible.

smoke alarms are typically set of by particles of dust - tiny tiny ones. If for whatever reason, that room has more dust than normal, that will be setting off the alarm.

is there anything else in the room that might generate hidden dust? old carpet, mattress that needs a mattress cover - that sort of thing.

We have smoke alarms in all bedrooms as well as landing, hallway, utility room and kitchen, linked together so if one goes off they all go off. Seems like a standard safety precaution to me.

You're "very paranoid about fires" suggests you have anxiety about it

Get an induction hob, or a less dangerous husband.

When we had our loft converted the building regs said we had to install smoke alarms in every room. So it seems normal to me.
Are fire alarms the same as smoke alarms OP? Or are you talking about a different type of device?
Ours go off sometimes around the changes of seasons, when they get dusty or when spiders walk over them. But mostly when I cook.

Less dangerous husband would be my preference. He's an absolute liability. 🤣

Agree with everything you've said except your use of the word paranoid. You're not paranoid (that would be something you really should get help for); you are more worried than most people about the risk of fire but it sounds as if it's not a problem in your day to day life, so it doesn't mean you need "help" with it. I think some people on here (and sm generally) need "help" with their compulsion to "diagnose" and advise. It's a dangerous game.

@Thismightbeouting Just a thought, don’t know if anyone has already said but could it be a smoker outside? Some window seals are not that tight and the detectors are very sensitive.

Are you a semi/terraced? Who/what's next door, could heat be coming from next door? . Excessive heat, could it be a cannabis factory?

I am not trying to diagnose clinical anxiety. I am saying you sound a bit over-invested in this whole thing.

And yet my behaviour is all perfectly reasonable. Go figure.

Yes, I'll accept that. It doesn't affect my day to day life at all.

Because I want a fire alarm up? 🤣

Because you want another fire alarm up in a house which is already adequately covered by fire alarms.

I get a bit cross when someone says that another poster should get help with her anxiety. What help? If she is a danger to herself or others, she could be sectioned (I know someone who has been and it was awful) but this is not the case. If the OP is able to go about her day to day life then the NHS is not going to offer expensive therapy.

I like the idea of the air purifier. Apart from anything else, it would be interesting to see whether it picks up a load of crud.

I have a similar problem since replacing my fire alarms.
My new ones are fireangel alarms with optical smoke sensing technology , and they go off constantly for no reason what so ever, I recently replaced several alarms in my house with them and they’ll be changed again as everyone is pretty much immune to the sound of them now as we’ve had so many false alarms. I prefer the ones that shout fire now anyway instead of bleeping , as so many devices bleep these days I’m not sure anyone would wake up.
