Fire Angel Thermoptek Smoke Alarm ST-622

The FireAngel ST-622 is a sealed 10 year battery powered smoke alarm featuring Thermoptek Multi-Sensor technology as used by over 90% of the UK Fire and Rescue Services.

Thermoptek Multi-Sensor technology constantly monitors for temperature change and if a sudden temperature rise is detected the sensitivity of the alarm is increased.

Optical and heat detection technologies increase the alarm’s sensitivity for a faster response. This provides a much faster reaction to both slow smouldering and fast-flaming fires in a single alarm.

The smoke alarm also benefits from 'Toast Proof' technology which reduces nuisance alarms. The smart silence button also allows the alarm to be silenced for up to 10 minutes in the event of a known false alarm. The handy "sleep-easy" function also allows the smoke alarm to be temporarily silenced for 8 hours.

This alarm has a tamper-proof sealed 10 year lithium battery and can be surface mounted on to a ceiling or wall.
