| Hi paul
I have fitted a wireless alarm to my house from B&Q, I know the alarm experts will cringe but it cost me £350 and covers all downstairs and the garage. It's easy to add extra PIR's or door/window magnet's and can operate 4 seperate zones. I think they are ideal for the older person as they have a remote keyfob to operate the alarm aswel as the keypad, so much easier for them to use.
