Awkward instal without patress Replacing old alarm on artexed ceiling so wanted to get it in the same spot. Plasterboard clashed with the tall, sticky-out plug in the centre so had to cut plasterboard away. That wasn't enough because the joist clashed with the plug so had to chisel some wood away too. A right palaver! If you want to install one of these with a joist in the centre spot, buy the base pattress as well. Also, tested with smouldering paper and it sounded, eventually. Pressed the button and it took 5 seconds to go quiet. One minute later it alarmed again. That button press is supposed to make it ignore smoke for a clearing period of ~10mins. I would recommend Kidde Firex KF2 or Aico instead. 6 Jul 2014
one to avoid It goes off about twice a week of its own accord. Have had to give up and disconnect. 8 Aug 2013
False Alarm Bought 3 of these alarms about 3 years ago and in summer one on lower hallway began false alarming(scaring my dog to death) changed batteries but became worse constantly alarming so has been disconected, not very good. 6 Jan 2013
poor performer Bought this 3 years ago as this type was supposed to give no nuisance alarms. But it was the only one which did. When it alarmed daily I changed the battery to no effect. Stick with the ionisation and heat alarms is my advice 3 Dec 2012
