Hello, Can anyone help? My intruder alarm goes off intermittently for no apparent reason. It may be okay for 3 days or 5 days then it will go off once a day, twice a day or sometimes 3 times, on the drive, on the road at work where I park and even sometimes in the garage. I cannot work out what the problem is, possibly a dodgy sensor. If anyone has any suggestions I will be grateful. Thanks Joy
