SIGA-HRD EDWARDS Intelligent heat detectors are designed with precision to detect either fixed temperature or rate-of-rise heat. They provide reliable and accurate detection, allowing for quick response to potential fires. With its advanced technology, these detectors offer a high level of safety and protection for any environment.

The Signature Series smoke detectors bring advanced sensing technology to a practical design that increases efficiency, saves installation time, cuts costs, and extends property protection capabilities. Continuous self-diagnostics ensures reliability over the long-haul, while the latest thermister technology makes these detectors ideal wherever dependable heat detection is required. The SIGA-HRD is an intelligent fixed temperature/rate-of-rise fire detector. It monitors the temperature of the surrounding air and analyzes the data from the sensor to determine whether to initiate an alarm. The rate-of-rise heat function quickly detects a fast, flaming fire. The fixed-temperature heat function detects fire when the air temperature near the detector exceeds the alarm point. With its high accuracy and fast response, the SIGA-HRD provides reliable protection for people and property in a wide range of applications.
