    I bought a mini smoke alarm for inside the van last year just as it was coming into winter. The problem was as the nights got colder the damn thing would start beeping all through the night. Eventually i gave up and took the battery out.
    It was fine as the weather warmed up so i carried on with it. However, when I was in the uk recently i bought a regular sized alarm and guess what, it has started going off during the night as well, only this one goes off proper, not just a beep!
    Does anyone have a reasonable explanation, could it be condensation...is there a better smoke alarm that would suffice?
    Forgot to add, they both do the same even if they are tucked into a cupboard for the night???

    Heres hoping (y)

    Cold batteries, no matter what type, are lower voltage in cold weather.

    A new battery will solve the problem as the alarm will have a low voltage cutoff point of maybe 7v for a 9v battery.
    if the battery is already low, say 7.5v, it will be even lower when cold

    It sounds like the new alarm is set to sensitive or has a fault......bin it and buy better quality.

    I agree with pappajohn, I had the same problem with a cold battery in the alarm fitted to my previous van, new bat & it was fine. I have even had the same problem with a dive computer switching off when jumping into cold water.:rolleyes:

    Your new alarm does sound to be faulty.
