Edwards KI-PHD Intelligent Smoke and Heat Detector

The Edwards KI-PHD detector brings advanced multisensor technology to a practical design that increases efficiency, 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.

In general, the KI-PHD provides an optical smoke sensor and a rate-of-rise heat sensor with a fixed temperature setting. Together, these sensors efficiently detect smoldering fires and fast-flaming fires. Like all KI Series detectors, the KI-PHD gathers analog information from its sensing elements and converts this data into digital signals. To make an alarm decision, the detector’s onboard microprocessor measures and analyzes smoke and heat sensor readings and compares this information to historical data. Digital filters remove signal patterns that are not typical of fires, thus virtually eliminating unwanted alarms.

Furthermore, the Edwards KI-PHD detects extremely small particles of combustion and triggers an alarm at the first sign of smoke. KI-PHD’s on-board rate-of-rise heat sensor provides a 15 °F (9 °C) per minute for the detection of fast-developing fires while also providing a 135 °F (57.2 °C) fixed detection threshold.
