The ground-breaking thermoptek technology in the st-622q provides responsiveness to all fire types in one alarm.
Thermoptek sensing technology – detects slow smouldering fires + rapid rise in temperature.

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.

• Battery powered smoke alarm – 10 year Panasonic battery lifespan (battery Included, never needs replacing)
• Toast proof – reduces nuisance alarms + Smart silence button
• Test & Smart silence button – allows the alarm to be silenced for up to 10 minutes in the event of a known false alarm.
