hold on, please correct me if im wrong but surely the alarm itself would be illegal in that case????
Ok I have some further info on this !!!
I spoke with an alarm fitting company, and they say, no the "chirps" are not illegal, to have sounding the area where there is a problem is the alarm sounding which is why all new alarms sold in the last few years can only sound for 45 secends then have to reset by law, and go through the cycle again, etc, etc, etc...
So there you have it, so providing the alrm isn't the main horn I'm going to get my "chirps" done shortly.
