Rapid Alerts to all Fires
Thermoptek technology combines the very latest in optical sensing with thermal enhancement and when compared to single sensor alarms react to fire in under half of the time - meaning you and your family have vital extra time to react.
5 Year Batteries Included
The unit comes with 2 x AA batteries that can be replaced once you hear the low battery chirp. 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.

COMPLETE THE RANGE…
Yes – we have a range of long-life smoke alarms in our range – found here. If you’re looking for a smart smoke alarm with optional notifications and testing via your phone then view our FireAngel Pro Connected alarms.
For the quickest alert to fire we recommend that the alarms in the home are all interlinked, either with a hardwired or wireless connection.
Our Pro Connected alarm range allows you to build a network across your entire home. For example, a network of 7 x smoke alarms, 3 x heat alarms, 3 x carbon monoxide alarms and a Gateway will be completely secure and protect your whole home.
In order to identify how many alarms to install you need to research the guidelines for fire detection that apply in your local area, using regulations such as Building Regulations or the guidance in BS5839-6, and consider your property type; whether that be private owned, rented, new build, renovated etc. The advice below is purely provided for ‘best practice’ and should not be used independently.

Smoke Alarms: To offer high protection FireAngel advise a smoke alarm within the circulation area of each floor of the property, as well as within the main habitable areas such as bedrooms and living room. 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.
Heat Alarms (Kitchen Alarms): Heat alarms are the only alarm suitable for use within the kitchen as they’re not affected by cooking fumes like traditional smoke alarms. Over 60 Percent of fires start in the kitchen, with cooking and faulty white goods (fridges and tumble driers) being the main causes. FireAngel recommend a heat alarm is fitted in the kitchen, but you can also fit additional heat alarms in the garage and loft to protect these areas.
Carbon Monoxide (CO) alarms: A Carbon Monoxide detector is the only way to be alerted to a carbon monoxide leak; it can’t be smelt, tasted or seen so it’s impossible for human senses to detect. Known as the ‘Silent Killer’, carbon monoxide (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. FireAngel recommend a CO alarm is installed between 1 m and 3 m away from each fuel-burning appliance, as well as installing additional units in areas such as living rooms and bedrooms where you spend most time whilst at home.
If the danger is smoke related the devices will be sounding the alarm in a three beep pattern – ‘beep beep beep’, with the red LED also flashing three times. If the danger is Carbon Monoxide related the devices will be sounding the alarm in a four beep pattern – ‘beep beep beep beep’ with the red LED also flashing four times.
