upon returning to the house yesterday and putting in the code to deactive the alarm, the tamper loop light came on - i cant recall if it was already on as soon as i entered the building, or if it came on after i put in the code - but it remained on untill i set the alarm later on that night and then went off. does anyone know what this means? i thought it might be low battery as a lot of other posts seem to suggest, but if this was the case wouldnt it have remained on still? anyone any other suggestions what it could be as now im paranoid someone has been trying to get in whilst we've been out.
