The KS-PS Photoelectric Smoke Detector is an intelligent device that gathers analog information from multiple optical sensors, converting this data into digital signals. Utilizing dual optical wavelengths combined with multiple detection angles, the KS-PS differentiates particles that are not representative of actual smoke. Data is digitally filtered to remove signal patterns that are typical of nuisance sources, thus reducing unwanted alarms. To make an alarm decision, the detector’s on-board microprocessor measures and analyzes all optical sensor readings and compares this information to a preprogrammed setting.
