Thermoptec technology combines the very lates in optical sensing, with a thermal enhancement. It constantly monitors for temperature change and if a sudden temperature rise is detected the sensetivity of the alarm is increased.

The smoke alarm technology of choice fro UK Fire and Rescue Services.

This optical smoke alarm works suing the light scatter principal.

As smoke enters the optical chamber, its particlase cause the infra-red light to be scattered onto a photodiode light receptor. Once light hits the receptor a signal is sent to the intigrated circuit causing an alarm to sound , alerting occupants of the recognised fire.
