Issue adding extension to alarm system

    Hi,

    I had an extension built onto the back of my house a few years ago and had it wired with alarm cable at the time.
    ____________
    |.........................|..................|
    | Original House.........................|
    |............................Extension....|
    |.........................|..................|
    ___________|

    The gap between the original house and extension is where there used to be a sliding door into the garden so I extended the alarm zone that the sliding doors were on to include the circuit of sensors in the extension (which consists of 5 combination shock and magnetic sensors).

    The problem is that I get intermittent false alarms on the extension circuit when I set the alarm.

    I have tried shortening the extension loop by 'shorting' out each of the sensors in turn to see if maybe I have a dodgy sensor somewhere but to no avail.

    I have tried disconnecting the tamper circuit and using it's wiring for the alarm circuit just in case to no avail.

    The only way I can stop the periodic false alarms is to completely short out the extension from the system (i.e. leave it un-alarmed).

    It's been like this for a while now and I've been considering putting a PIR into the extension (it's one big room) to at least provide some security... Can I just add a PIR to the zone or are there other considerations? I guess the PIR would require a power source...

    Anyone got any suggestions?

    It's an Aritech alarm that was in the house when I bought it btw...

    Cheers.

    What sensors are you using ? If they're HKC are the arrows on the sensor head pointing upwards ??

    Its possible you have a faulty sensor on that zone. The best way to find a faulty sensor or contact is to check the resistance on the whole zone. If you have the use of a multi meter follow the instructions in post 9 of this thread.

    I know you have said you have shorted out each sensor in turn , but this method will show you exactly what the panel is seeing.

    Also check to see if anything else is on that zone, just in case there is a window or two from the original house.

    Thanks for the replies guys.

    Thunderbird2: Yup they are all orientated correctly.

    KoolKid: Thanks for the link, I think I might give it a go....

    Altor: Yeah I labelled all the sensors in the house with their appropriate zone when I wired up the extension. There is only one window from the original house on the circuit with the extension and I even tried shorting it out too...

    The issue is definitely something to do with the extension...
