Edwards EST SIGA-PHD Multisensor Smoke and Heat Detector

Edwards EST SIGA-PHD Multi sensor Smoke and Heat Detector  The Signature Series SIGA-PHD detector brings advanced multi sensor technology to a practical design that increases efficiency, saves installation time, cuts costs, and extends life safety and property protection capabilities. Continuous self-diagnostics ensures reliability over the long-haul, while environmental compensation helps reduce maintenance costs. The SIGA-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, as well as fast flaming fires. Like all Signature Series detectors, the SIGA-PHD gathers analog information from its sensing elements and converts this data into digital signals. To make an alarm decision, the detector's on-board 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.
