The optical-thermal detector from the Series SOTERIA contains both an optical sensing chamber based on the principle of dual angle scattered light as well as a temperature sensor according to EN 54-5 Class A1R. The detector has been tested to EN 54-29, EN 54-7, EN 54-5 and EN 54-17. The detector has a thermal-only mode according to EN 54-5 Class A1R (rate-of-rise heat detection principle), as well as 4 multisensor levels.
The 3-criteria detector from the Series SOTERIA contains an optical sensing chamber based on the principle of dual angle scattered light, a temperature sensor according to EN 54-5 Class A1R, as well as a CO sensor. The detector has been tested to EN 54-31, EN 54-7, EN 54-5 and EN 54-17.
The evaluation of all parameters and the integrated comparison of characteristics of fire allow reliable fire detection. The optical evaluation based on the dual angle principle ensures that smoke can be reliably distinguished from noise variables, therefore the immunity to deceptive alarms is increased significantly.
The detector has a thermal-only mode according to EN 54-5 Class A1R (rate-of-rise heat detection principle), as well as 4 multisensor levels.
The detectors are compatible with the Detector Base SA5000-200 which is already known. However, the address card is not used. The address of the detectors is set by means of a DIP switch on the detector.
