KI-OSCD

 Overview
The Kidde Intelligent Optica Series KI-OSCD 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. 
 The KI-OSCD provides a combination of optical detection for 
the early detection of smoke, with the added element of carbon 
monoxide sensing. The result is a detector that pulls double duty: 
continually monitoring the environment for signs of fi re, as well as 
its invisible yet deadly companion, carbon monoxide. 
Like all Kidde Intelligent Optica Series detectors, the KI-OSCD 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-OSCD 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. The detector also 
analyzes the smoke sensor independently from the CO sensor to 
determine whether to initiate a fi re alarm, a life safety CO alarm, 
or both.
