  1. Don't think it can be the easy one. low batteries as they are hard
    wired in to the power. They are located in our Stairwell in our
    building. One is right at my door and has a high pitched SCREECH :(

    They seem to be going off at the same time one after another. Not all
    of them just some of them.

    I was thinking maybe they were left in a TESt mode or something. As
    iam pretty sure Smoke alarms don't make noise till they need to :)



    Any ideas.

    Going to call our buildings Strata, people who look after the building
    to get it fixed anyways. Just like to know your thought son the matter
    :)

    Thanks.
     


  2. Bugs! I've found dead spiders in several smoke alarms that were
    acting funny.

    Are you absolutely sure that there`s no battery in there? My house has
    wired in smoke detectors, but each one has a PP3 in little drawer on
    the side. When the PP3 discharges, the detectors beep, even if the mains
    power is in.

  4. They are pretty new so i don't think bugs. Unless they are shit alrms
    and defective and those are the bugs :)

    Keep em coming :)
     
  5. I once stayed in a hotel with a smoke alarm that would chirp every 2
    minutes. It was also wired into the mains power. My solution was rip it off
    the wall.. It kept beeping and I had to find the battery in it and rip that
    out also.. I finally got some sleep after that.

    Hard wired alarms are usually connected together, so if one goes off,
    they all go off. Typical of a multi unit residence.
    Also, many have a battery back up.
    You should have long since called the property owners.

    Could be a surge or pulse on the power line. I learned this from a
    fireman who had to go around resetting lots of alarms in apartment
    buildings.

    This would explain why many of them (but not all) go off at once. (If
    they were wired together to go off at the same time, then all of them
    would go off.)

    If it is a problem with surges on the power line, it will affect other
    buildings served by your power substation.
     
  8. I opened mine up in my place, the same ones are outside. And yes they
    do have a battery in them. I suppose they need some new ones.

    Ill ring some people up tommorrow and get ALL teh batteries replace.
    Shouldhave some peaace for atleast 15 months i hope :)

    I hope thats the problem. Easy enough to fix.

    Thanks all.
