Fire detector provides alternative to ionisation fire detectors
Published: October 2007
The PITR photo-thermal infra-red detector from System Sensor Europe has been developed to provide an efficient and environmentally benign alternative to the venerable ionisation detector. PITR sensors are designed for the rapid detection of fast-flaming fires and consist of independent photo-electrical, thermal and infra-red sensors, which are managed and controlled by sophisticated algorithms running on an embedded processor. The addition of the infra-red sensor to the established photo-thermal multi-sensor design is said to increase performance so that it can replace ionisation detectors with no degradation in speed of response or generating more false alarms.
