Reviews
Mains Heat Alarm 690MBX 230V + 9V Backup is rated 4.3 out of 5 by 4.
Rated 5 out of 5 by from Gtreat heat alarm at good price As always with Toolstation great service with products which are always good value. I find it hard to beat most of their prices so will always use them as my bench mark.

Rated 3 out of 5 by from Wrong colour I needed to replace an existing alarm which is why I bought this particular item but as others have mentioned it is grey and wouldn't buy again for that reason.

Rated 4 out of 5 by from Does what you need! Got a few of these to fit in replacement of existing ones that had come to end of their life, easy to fit, battery compartment screw is a bit fiddly and they aren't really sturdy compared to aico smoke alarms but they are half the price and do the same job!!
