Overview

 

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. 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.

Application


The SIGA-HRD combination fixed temperature/rate-of-rise heat detector provides a 15 °F (9 °C) per minute rate-of-rise heat sensor for the detection of fast-developing fires, as well as a 135°F(57°C) fixed temperature sensor for slow building-fires. The SIGAHFDfixed temperature detector provides a 135°F (57°C) fixed temperature sensor for slow building-fires.


Compatibility


Signature Series heat detectors are compatible only with the Signature Loop Controller.

 

Installation


Signature Series detectors mount to North American 1-gang boxes,3-1/2 inch or 4 inch octagon boxes, and to 4 inch square electrical boxes 1-1/2 inches(38 mm) deep. They mount to European BESA and 1-gang boxes with 60.3 mm fixing centres. See mounting base installation and wiring for more information.
