Like the FireAngel ST-622Q below, it uses the firm’s Thermoptek sensor, giving it high sensitivity without excessive false alarms.Where your alarm is installed can trigger nuisance alarms if not correctly placed, for example too close to doors or windows. 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. I shall only be able to report on the excellent performance of this item whilst standing in the street outside the smouldering ruins . This and the 10-year sealed-in battery means they’re compliant with recent changes to Scottish legislation, and that you won’t miss out on an alarm if you live in a larger property, have a hearing impairment or spend a lot of time with the TV blaring or your headphones on.

ST-622 smoke alarm with Thermoptek™ thermally enhanced optical sensing to provide fast reaction to both slow smouldering and fast flaming fires in a single alarm. In 2022, Scotland added further legal requirements that smoke alarms fitted in a home be interlinked, so that if one goes off, they all go off. Thermoptek technology combines the very latest in optical sensing with a thermal enhancement, constantly monitors for temperature change and if a sudden rate of temperature rise is detected, the sensitivity of the alarm is increased.
