The Edwards Est 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. Also, the rate-of-rise heat function quickly detects a fast, flaming fire. Besides, the fixed-temperature heat function detects fire when the air temperature near the detector exceeds the alarm point.
In fact, 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 ensure reliability over the long haul, while the latest thermister technology makes these detectors ideal wherever dependable heat detection is required.
Furthermore, Edwards Est SIGA-HRD mounting bases have wiring terminals that are accessible from the “room-side” after mounting the base to the electrical box. Additionally, the bases mount to North American 1-gang boxes and to 3½ inch or 4-inch octagon boxes, 1½ inches (38 mm) deep. They also mount to European BESA and 1-gang boxes with 60.3 mm fixing centers.
