    proximity alarms

    just wondering,is there a proximity alarm out there that is compatible with the factory fitted alarm in a 2001 astra mk4?

    i ask because of my recent issues with having wipers nicked off my car,and the fact that my car is parked on the street in a pretty sketchy area where cars are regularly vandalised and broken into.

    do you guys think a prox alarm would be any more of a deterent to theft/vandalism?

    I dont think it will help at all....
    ..if its kids pinching wipers, they'll just go near your car all the time just to set the alarm off...

    Maybe quick release wipers would be a good option...

    i have a suspicion it was someone after some replacements,i live in a student town,so it wouldnt suprise me if some tight-ass half inched them.

    i guess theres the danger that a prox alarm would invite more trouble than it would prevent.

    A stand alone proximity sensor will have 2 outputs.

    Depending how you wire it could be wired to the standard alarm.

    Just wire one of the outputs through a relay so when its triggered it grounds a wire. You can then attach the wire (Through a diode) to the door pin switch.

    ive got proximity sensors on my mk4 gsi. Now ive got two alarms on it, the standard and a new one, but they work in sync so im guessin its not technically wired into the vaux alarm as such but as the two alarms are linked it does the same thing. it wont set the alarm off tho. no matter how many times it bleeps.

    If wired up like Lee said it will result in a full alarm trigger

    Yeah thats right.

    I have a Pizo buzzer wired to the outside zone and as above for the inside zone.

    That way it beeps when people are too close and sets off the alarm if anyone was to reach in.
