We have a factory fitted PIR on our alarm, now when the PIR picks up movement inside the van, not only does the red lights flash but it's also making a wierd noise, this is becoming very annoying. Can anyone help, thanks. Julie
Thanks we worked it out, we thought that the PIR was wired in to the electricial system and as we had just had just changed our leisure battery thought that might have something to do with it. Didn't realise that it was run by a PP9?
My PIR was singing like a canary - I thought something was trapped in the caravan wall lol.
I put a new battery in following the above advice, but now instead of just "cheeping" every now and then, it screams when detecting movement and the lights flash on it.
