KI-OSD
Optical Smoke Detector
KI-OSD Optical Smoke Detector uses an optical sensing chamber to detect smoke. The detector analyzes data gathered by the sensor to determine when an alarm is initiated. Thanks to its high-performance optical sensing chamber, the KI-OSD responds quickly and reliably to a wide range of fire types, especially slow burn ing fires fuelled by combus tibles typically found in modern multi-use buildings. The KI-OSD detects extremely small particles and triggers an alarm at the first sign of smoke.
Overview
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.
