OK this is the perfect DIY alarm, easy to fit and use. The siren is brightly coloured which I think is a good thing and it gives out a perfectly adequate load alarm. However, the control unit is not truly wireless, it does have back up batteries but it needs to be plugged in to a socket. My advise would be to only purchase this set (SA3) if you need to have some rooms on separate zones. This control unit has 6 zones and you can choose which zones are set when you press "Part Arm". If you don't need zoning then go for the SA2 package. So far I am very happy with this purchase.
i fitted 1 a few years ago,when friends and relations saw it they all wanted one , so i installed another 4 they are great pity i no longer work or i could have made a fortune.
