FireAngel are committed to developing technologies which provide the highest levels of fire detection for your home.
With power inputs to suit all installations, including sealed, tamper proof, batteries or mains powered options with back-up batteries, you can be confident your FireAngel device will protect you for years to come.
Testing your smoke alarms no longer means you need the step ladders - FireAngel have you covered with a large central push button!
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.
The unit comes with a sealed, tamper proof battery that will last the lifetime of the alarm. 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.
As well as allowing easy testing with a sweeping brush from the floor below, this large button also activates our Sleep Easy function which silences low battery chirps for 8 hours - giving you a peaceful night's sleep.
No – the ST-622 has not been designed to be installed in a kitchen as it will react to cooking fumes. For fire detection in your kitchen fit a FireAngel Heat Alarm – found here.
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.
