Description

The KS-PHD Combination Photoelectric Smoke and Heat 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-PHD differentiates particles that are not representative of actual smoke. Data is digitally filtered to remove signal patterns that are typical of nuisance sources, 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.

Additionally, an intelligent fixed temperature/rate-of-rise heat sensor is embedded in the KS PHD device. The heat sensor monitors the temperature of the air in its surroundings and the microprocessor analyzes the data to determine whether to initiate an alarm. The KS-PHD initiates an alarm based on either heat or smoke detection independently.
