The Kidde Intelligent Optica Series KI-OSD smoke detector brings advanced optical (photoelectric) sensing technology to a practical design that increases effi ciency, saves installation time, cuts costs, and extends life safety and property protection capabilities. Continuous self-diagnostics ensure reliability over the long-haul, while environmental compensation helps reduce maintenance costs.

Like all Kidde Intelligent Optica Series detectors, the KI-OSD 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 KI-OSD differentiates particles that are not representative of actual smoke. Particle data is input into digital fi lters which feed a series of ratios removing 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 preprogrammed settings.
