BRK 660MBX Thermal Optical Smoke Alarm is rated 4.2 out of 5 by 14.
Rated 4 out of 5 by from False alarms? False alarms were driving me crazy! So these direct replacements for the previous ionisation models did the job....spend the extra and fit thermal optical first....

Rated 4 out of 5 by from Good for the price An easy to fit smoke alarm fitted into a buy to let as have to be mains operated now. Easy to fit, but with the surface mount plate does make it stick out quite a way. Good as you have the option to hardwire link to other smoke alarms as is required in buy to lets if putting more than one in the property

Rated 4 out of 5 by from Good replacement product Had to replace an old smoke alarm, this model was recommended as it would fit into the existing housing. However the connector had to be changed (supplied with product) which is bigger than the original so I had to use some spacers and longer screws to make it work. Product now fitted and fully functional - very pleased.

Rated 5 out of 5 by from Quick replacement I am having my hall decorated so decided to upgrade everything. These alarms are easy to fit and very effective. All the fittings were there already so didn't take very long to replace. Would definitely recommend.

Rated 1 out of 5 by from Colour Mismatch I recently purchased the BRK 660MBX and BRK 690MBX detectors together with the surface mounting pattress. Firstly the pattress is white and the detectors are a greyish / beige colour and do not match. In fact they look rather ugly. Whilst the pattress makes for ease of wiring it does make the unit look rather large. After investigation I purchased the BRK 760MBX and BRK 790MBX detectors. These have an integral mounting plate for easy connection and look much better than the 660 and 690 options. The units are about the same price so using them is a no brainer.

Rated 5 out of 5 by from Reliable Kit I have used these loads of times they never let you down, works every test keep them clean, change the battery when you should and you get your ten years out of them
