JHC & Andrew I feel that I must agree with Andrew and the law will possibly make an example of someone eventually to make everyone aware that the law is the law. On careful reflection I feel that the only safe method is a compliant fence, the alarm is OK for some of the time but they will fail as all electronic devices do and unless you have a back up system such as spare alarm one would be liable. My supplier also spoke in terms of " well it is unlikely that you could be prosecuted if the alarm is away being repaired etc." but in my opinion he is talking through his hat and as he would not be paying the fine he does not have to worry. The circuit board is so small and could only cost a few euros to make it would not be expensive for a supplier to have couple in stock to facilitate a speedy repair, they after all are making a tidy profit from an easy sale. I now wait for several weeks while my alarm is being repaired hoping I do not receive a visit. I will also be investigating a consumer bureau that I have heard about to see if they have any interest in pursuing the matter. Ray
