By duncant

"Bought these to replace missing smoke alarms in my house. Was easy to wire in the connector to the terminal block that was already in the ceiling. As others have pointed out, you really need a lining box to screw the mounting plate into and to house the connector plug.
Seems to work well

Top Smoke Alarm
10 May 2012
By Nozzil
, Grantham
"I bought this to replace a similar model that had just failed after almost 10 years. With the same electrical connector and mounting plate, it fit exactly where the old one had been. The manufacturer (BRKDicon) service department were also brilliant; an engineer even phoned me back to chat through the fault with the old alarm (great customer service even if the old alarm was knackered!). Great product at a great price."

The smoke alarm of choice

"These alarms use regular batteries as back-up as opposed to capacitors or own brand etc.
Can add as many as necessary for alarm system plus different types of same make.
Excellent price and never had any fail yet.

"Less sensitive that the model I bought this to replace, but as it's next to the kitchen, that's no bad thing. This one doesn't go off unless the toast is actually burnt, whereas the previous one would tell me when it was just cooked!"

Dicon Alarm
27 Nov 2009
By AnchorMan

"Good value for money. Easy to install, personally I use a dry lining box in the ceiling to mount to, prevents dust and allows room to push the plug into. Read the instructions for mounting position and where to get the supply from."
