Why does our smoke alarm go off when nothing is burning or even cooking?

It went off at 05:30 this morning when we were all asleep:-s
It's done it several times in the last month when neither the hob or the cooker are on and there's been no fire lit in the grate since March. None of us smoke either. Is it faulty? Thanks for your answers:-)
 
If its battery operated change the battery it may need a new one, there are smoke alarms and heat alarms so if its a heat alarm it may be getting hot in the room and setting it off - summertime and a closed room and central heating or some heater close to it could set it off. If its a Carbon Monoxide detector then you may have a problem with your gas or oil fired boiler causing CO in the air dangerous if that is the case - if it really is a smoke alarm then change the battery if that does not work change the alarm buy a new one - if its attached to the main electric supply and not battery operated you will need an electrician or someone that is very competent with electric but for safety get a qualified electrician.
 
Either the battery is low, or it's broken. The third answer you won't like... your house sticks (do you have a lot of cats with the litter box near the alarm?).
