Key feature FirAngel smoke detector

The FireAngel ST-622 is the best replacement for conventional alarms. The ST-622, which includes ThermoptekTM technology, combines the most recent advancements in optical sensors with thermal enhancement to provide faster response to both types of fire.

Thermoptek™ technology

ThermoptekTM technology combines the most recent advancements in thermal enhancement and optical sensing to deliver quick response to both slow-smouldering and quickly blazing flames in a single alarm. The ST-622’s ThermoptekTM technology eliminates the requirement for ionization alarms by providing responsiveness to all fire types in a single alarm.

Sleep Easy Function

Low battery notifications frequently appear at odd hours or when it could be difficult for you to change your alarm. The ST-622 enables you to mute the frequently inconvenient low battery warning chirp until it is convenient for you to change the alarm, which will silence the audible chirp for eight hours. During this time, the detector will continue to detect smoke, but it also gives you a simple way to stop the obnoxious beeps.

Heat Detector

If you are looking for a suitable Heat Detector FireAngel also offer the HT-630T Battery Operated Heat Alarm.
