The Edwards Est SIGA-HRD i s an intelligent fixed temperature/rate-of-rise fire detector. It monitors the surrounding air’s temperature. And analyzes the sensor’s data 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 w hen the air temperature near the detector exceeds the alarm point.
The Signature Series smoke detectors bring advanced sensing technology. To a practical design that increases efficiency, saves installation time, and cuts costs. And extends property protection capabilities. Continuous self-diagnostics ensure reliability over the long haul. W hile the latest thermister technology makes these detectors ideal wherever dependable heat detection I s required.
Edwards Est SIGA-HRD mounting bases have wiring terminals. These a re accessible from the “room-side” after mounting the base to the electrical box. The bases mount to North American 1-gang boxes and 3½ inch or 4-inch octagon boxes, 1½ inches (38 mm) deep. They mount to European BESA and 1-gang boxes with 60.3 mm fixing centers.
