BRK 670MBX (679) Dicon Ionisation Alarm with 9V Battery Backup is rated 4.2 out of 5 by 127.
Rated 5 out of 5 by from good level of senstivity My builder was happy to fit this as he had recommended one that is connected to the mains power for extra safety cover, which this does. Have managed to set this off the few times I have burnt toast roughly 3-4 metres away from the alarm, but easy enough to mute it.

Rated 5 out of 5 by from Excellent Smoke Alarm Have used these previously so makes sense to replace with same units, saves changing base plate and connectors. Excellent value and peace of mind knowing that I can rely on them.

Rated 4 out of 5 by from Long lasting The basic design of this smoke alarm means hopefully it should last the 10 years it's designed for. It has a green light for mains power and a red light that flashes every 45s to indicate the battery is ok, you can also connect alarms together with an additional wire connected between them. It's easy to fit and is quite slim to the ceiling, the only negative is it's more beige in colour than white but it's cheaper than other smoke alarms that do the same job.

Rated 5 out of 5 by from Quality Home Smoke Detector Replacing them regularly saves easy swap out and no excuses when they are this inexpensive.

Rated 4 out of 5 by from Good Unit The unit is simple and basic to install. A little annoying that the battery back up is only able to be changed by removing and unplugging the unit then unscrewing the securing screw as the old units were slide in and out, but they work well. Standby green light is a little bright and the 45 second red light standby is annoying, but you don't notice it after a bit. This flashing might have upset someone as I bought 2 units, one all new and sealed, the second, ripped box, battery tab ripped off, battery cover Phillips screw replaced with an old slot head screw (I know this as new unit screw was taped down and shiny and old unit was screwed in) and electrical cables stripped and crimped, not to mention the base plate had signs of fitting and the protective smoke cover (like a tiny shower cap) was refitted backwards, so be cautious of returns, but I needed to get them fitted and they work fine.

Rated 5 out of 5 by from Easy to daisy-chain to enable full house alert I purchased 3 of these a couple of years ago and interconnected them so that if one goes off, the other2 do. Easy to wire and if purchased with the mounting kit - you have no issues with wires and stowage. Reasonable price and in my view a good product.
