Overview
▪ The built-in CPU with A/D converter stabilizes the smart fire judgment algorithm program and automatically analyzes actual fire hazards to reduce false alarms;
▪ The unique optical maze structure and backscatter structure are used to ensure balanced responsiveness to black and white smoke alarms;
▪ Self-diagnosis: Indicates the maintenance requirements when critical elements are aged, failed or faulty;
▪ Self-compensation: Automatic tracking compensation is activated when dust accumulates within a certain range;
▪ Indicate the cleaning requirement when the allowable limit is exceeded;
▪ Indicator status: In patrol mode when the system operates normally and steadily on when a fire alarm occurs.
▪ Electronic coding, non-polarity two-bus, easy and convenient to install;
▪ Used in places where a large amount of smoke and a small amount of heat are generated during a fire, such as hotels, shopping malls, office buildings, schools and other indoor places.
