Edwards Signature Multisensor Detector for EST3 and EST3X Panels

The Signature Series SIGA-PHDI 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 ensures reliability over the long-haul, while environmental compensation helps reduce maintenance costs.

The SIGA-PHDI provides an optical smoke sensor and a rate-ofrise 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-PHDI 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.
