Carbon Monoxide Alarms Carbon monoxide (CO) alarms can be placed anywhere, not just the ceiling or high on a wall. They should be replaced every 5 to 7 years. Heat Alarms Heat alarms are ideal for areas where smoke alarms aren’t suitable such as those with high humidity, dusty environments or areas where non-dangerous smoke is generated like kitchens, garages or lofts. Review: Shame it has been discontinued. - This was to replace exact same one that had lasted 9 years. Reliable. Easy to install & unobtrusive. Shame it has been discontinued. Review: Brilliant !! - Bought two of these as both of our original smoke alarms that were fitted to our house from new (12 yrs ago and a different brand!!) had passed their sell by date and were continuously bleeping similar to if the battery was dead in them but even with new batteries the bleeping did not stop which firmly indicated both were dead as a door nail ! These smoke alarms fitted exactly in the same footprint as our old ones and there was no need to re-drill for the mounting rings as there are plenty of fixing holes which matched up to where our original screws were to the old ones. Would highly recommend these as they are so simple to retro fit if you need to replace an old smoke alarm or indeed if also easy to fit in a new installation having not had one before. 5* from us !!!!! ## Features - Sensitive ionisation smoke-sensing technology with a loud 85 dB alarm that can be heard easily - Multi-alarm interlink system allows you to connect up to 12 mains-powered alarms for simultaneous warning - Alarm-source indicator helps you quickly locate the problem - 230 V primary mains power with included 9 V battery backup - Backed by a 5-year guarantee; measures 133 mm (D) x 38 mm (H) - 5-year guarantee BS EN 14604: 2005 ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | BRK | | Part Number | 670MBX | | Product Dimensions | 4.4 x 13.8 x 13.8 cm; 210 g | | Batteries | 2 AA batteries required.

Reliable. Easy to install & unobtrusive. Shame it has been discontinued. ### ⭐⭐⭐⭐⭐ Brilliant !! *by M***S on 15 October 2019* Bought two of these as both of our original smoke alarms that were fitted to our house from new (12 yrs ago and a different brand!!) had passed their sell by date and were continuously bleeping similar to if the battery was dead in them but even with new batteries the bleeping did not stop which firmly indicated both were dead as a door nail !

As others have mentioned the bracket was the same so it was a matter of removing the old one and putting in the new ones, after making sure the batteries are in. The validity of the units I got were for 9.5 years, which I think is acceptable given that between production and distribution there will always be sometime lost, but for the price you pay it makes it very good value for money at just over Β£1 per year of use, and for a peace of mind that is priceless! --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/55795438-brk-670mbx-ionisation-smoke-alarm-mains-powered-with-9-v](https://www.desertcart.gr/products/55795438-brk-670mbx-ionisation-smoke-alarm-mains-powered-with-9-v) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-09-13*
