Yesterday the fire brigade broke down my door because the smoke alarm was going off, but there was no fire.
Today I am off work.
There’s building work going on two floors below, I have closed all windows and cleaned all dust as I think this may have been the cause. But it’s still
happening! I’m going insane! I tried hoovering the alarm, I unscrewed it and shook a bit of dust out. It’s mains attached so don’t think I can turn it off, plus obviously need a smoke alarm!
Anyone ever had this??

so there i am, rubbing down the swedish bowling cheerleaders with oil when one looks at me and says...
BEEP! BEEP! BEEP! BEEP!
smoke alarm going off. i jump out of bed, and by the time i got into the hallway, they stopped. checked all the rooms, no smoke, no fire.
they went off for a total of about 30-45 seconds. any idea why then would have gone off like that for no reason??
on a related note, with regards to a co2 detector, how would you know if it was a false alarm or not? we currently do NOT have one, so i know thats not what set the alarms off...
any ideas?
We've all experienced the panic of hearing a smoke alarm go off and immediately jumping into action mode -- only to realize there's no emergency. The loud beep is grating and you may even be tempted to remove the batteries, but that could leave your home vulnerable to a real fire.
Before your frustration builds to the point of battery removal -- or insanity, follow these safety and prevention tips. Read more to find out why your smoke detector goes off and how you can deal with the false alarms.
How smoke detectors work
There are two different types of smoke detectors. Ionization smoke detectors have two plates with an electric charge flowing between them. When something -- like smoke -- flows between these two plates, the electric charge is interrupted and the alarm is triggered.
Photoelectric smoke detectors have a small light inside. When something enters the detector and reflects the light onto a sensor, the alarm is triggered.
Notice how both of these types of detectors don't really detect smoke. They're triggered by foreign objects interacting with parts inside the detectors. This means that anything that can float into your smoke detector, like vapor, steam, smoke and large puffs of dust, can trigger your smoke detector.
This is why it may go off when you're cooking, even if you're not burning anything. The steam coming off of the food is triggering the alarm. Hair spray and other aerosols sprayed near the detector can set it off, too.

See all photosHow to cope
The most obvious way to cope with annoying smoke detectors is to take them down. But that leaves you vulnerable if there is a real fire and isn't safe at all. Don't do it.
Instead, install your smoke alarms in strategic places, ventilate the area and replace old alarms.
Place your smoke alarms carefully throughout your home. Photoelectric smoke alarms are best near bathrooms and kitchens where there's a lot of steam because humidity doesn't affect them as much. Note that the National Fire Protection Association recommends placing detectors 10 feet (3 meters) from your stove to help prevent false alarms while cooking.
Next, be sure to use your kitchen's exhaust fan when cooking. If you let the smoke and humidity out through the fan's duct, it'll be less likely to set off your smoke alarm. Be sure to also use your exhaust fan or crack a window in the bathroom to prevent humidity or aerosols from wafting out to the alarm.
If you don't have smart smoke detectors, you may want to consider installing them. Some smart detectors include Nest Protect, Halo Smart Labs, First Alert and Roost.
You can quickly shut off these detectors using an app on your phone if there's a false alarm. Smoke detectors are far less aggravating when you don't need to climb on a chair to shut them off.
