The ground-breaking thermoptek technology in the st-622q provides responsiveness to all fire types in one alarm.
Thermoptek technology combines the very latest in optical sensing with a thermal enhancement. It constantly monitors for temperature change.
Smoke is detected by an infrared detector which, when interrupted by smoke particles, scatters light onto a photodiode receptor.
This is the Sensing technology of choice for the UK’s Fire and Rescue Service and gives a response time of up to 50% faster than normal smoke alarms.
