The FireAngel ST-622 smoke alarm utilizes a patented optical sensor with THERMOPTEK technology, which reacts twice as quickly to actual fire sources compared to competing detectors. This detector is equipped with two additional heat sensors allowing rapid response to smoke associated with fire. An 85 dB sound alarm along with visual signals warns individuals in the danger zone.

This alarm is certified according to the EN14604 standard, confirming its compliance with the highest safety standards, and is suitable for installation in homes and public buildings. It is recommended to install alarms in various areas of the house for maximum protection.

Thanks to the integrated lithium battery that requires no replacement throughout its life, the ST-622 provides long-term protection with low operating costs. In case of a false alarm, the signal can be easily silenced by pressing the test button.
