    hi all.
    I have a problem that just came up in the last week. getting false alarms from my sensors. yesterday alarm went off when I was out saying zone two alarm. got home everything was sound. today it happened again but a different zone.
    maybe it was a mouse but I don't think a detector would pick up something that small unless it abseiled across the front of it.
    so I was thinking it has been relatively sunny the past three days. would the difference in air temperature between the zones cause them to activate. sun moves across the house over the course of the day. area where zones are located is front and back.
    Either that or there is a mouse eating cables, ya reckon.........
    cheers

    Are these zones areas or windows? If the latter, is there any chance someone has been hitting the windows with a ball?

    If there are sensors & contacts on those zones there may be one or more faulty devices on those zones. The only true test is to check the resistance on those runs.
    See Post 9 here if your useful with a multi meter.

    thanks for the reply, they are zones. no chance of any thing disturbing them at all.

    funnily enough the second time it happened, they closed the doors in the rooms leading to the areas that had previously set off the alarm and it has worked away grand since...maybe a coincidence, don't know. the alarm has been in three years with no grief, so "koolkid" do you reckon the resistance could be an issue....

    Checking the resistance is the only true way to test the zone(s).
    I would reckon there is a faulty device somewhere.

    I would also check the sensor heads in your case as you have said closing the door stopped the issue. May not be sitting correctly in the sensor.
