I would recommend this product Only used this for one day so far and I can say it is a top investment. Another 3 or 4 days use and it has paid for itself, saving hire costs. I would recommend this at twice the price to be honest. 12 Nov 2014
heat detector I fitted one of these today along with 3 smoke detectors. Worked first time, but do get the patress as it does make installation much easier. The part number is 30152 8 Sep 2012
very good product excellent product. Instructions clear & detailed. Would buy again. 25 Mar 2009
Counter-productive The large plug on the back of this thing means you have drill a large hole in your ceiling to fit it, and you can't fill it in afterwards. This might invalidate the fire rating of your ceiling. A recessed plug would make life much easier. This problem applies to other alarms in this series. 21 Nov 2008
