We have had no problem with this alarm in the 9 years it has been installed. However we had new carpets fitted last Thursday and once the fitter had gone and we went to set the alarm to go out we had what looks like a t on the panel!? From the instruction manual I can see the t is for tamper zone but my question is how can I get rid off this? I am thinking the cables running in one of the bedrooms might have been cut or damaged by the fitter. Do I have to get the alarm engineer out or is there a code I can put in to try and correct the problem first? Hope some one can help!
