FireAngel heat alarms have been specifically designed for areas with fumes and high humidity such as kitchens, where cooking fumes are present, and attics or garages where there is lots of dust.

We’ve made testing at home all the easier, with a large, central test button and the ability to easily silence known false alarms to 10-minutes giving you time to waft away the smell of burnt toast and return to peace and quiet once again. The unit comes with a sealed for life, tamper proof lithium battery. The sensor within the unit will deteriorate after 10 years, so to ensure you’re protected we recommend you replace the unit after this time.Powered by a 10 sealed lifetime battery, the FireAngel FA6620-R optical smoke alarm detects slow smouldering fires and gives you the earliest warning possible to a fire. Suitable for installations throughout your home, including hallways and landings, as well as in leisure accommodation vehicles (LAV), such as motorhomes and caravans. Replace your old FireAngel ST-622 with the FA6620-R, as it uses the same base plate requiring no additional holes or need for redecorating. Our new heat alarm features Thermistor heat sensing technology to ensure you’re alerted to fires without the false reactions to cooking fumes. For faster detection, search for FireAngel Thermistek.

Known as the ‘Silent Killer’, CO occurs when fuels burn incompletely, with common sources being boilers, gas fires and hobs and solid fuel burners. However, carbon monoxide can also pass through walls, so you would also be at risk if a neighbouring property had a leak.From April 2022, FireAngel is launching a new range of optical sensor smoke and Thermistor sensor heat alarms. These alarms feature an array of exciting features and will be replacing a few of our current units. Looking for a FireAngel ST-622 or ST-620 smoke alarm replacement? With the FA6620-R, you can replace your end of life alarm without requiring a new base plate or leaving unsightly holes in your ceiling. It’s important to remember that the sensors in all smoke alarms deteriorate after time, at FireAngel we recommend that smoke alarms are replaced every 10 years.
