The DS-PS Photoelectric Smoke Detector is an intelligent device that uses an optical photoelectric sensing chamber to detect smoke. The detector’s built-in microprocessor measures and analyzes sensor readings, making comparisons to historical data and filtering signal patterns that are not typical of fires to prevent unwanted alarms. The practical design of the DS-PS increases efficiency, saves installation time, cuts costs and extends life safety and property protection capabilities. The DS-PS detects extremely small particles of combustion and triggers an alarm at the first sign of smoke. With its high-performance forward scattering reflective response technology, the photoelectric smoke sensor responds quickly and reliably to a wide range of fire types, especially slow burning fires fueled by combustibles typically found in modern multi-use buildings.
