Edwards Est SIGA-DH Duct Smoke Detector

The Edwards Est SIGA-DH Duct Smoke Detector Housing is specially engineered to exploit all the capabilities of Signature Series intelligent photoelectric and multisensor smoke detectors. Also, Edwards Signature Series detectors gather analog information from each of their one or more sensing elements and convert it into digital signals. Besides, the detector’s onboard microprocessor measures and analyzes these signals. It compares them to historical readings, time patterns, as well as known characteristics to make an alarm decision. Digital filters and complex Algorithms are applied for optimum detector accuracy. Unwanted alarms are virtually eliminate.

In general, each duct housing comes packaged with detailed installation instructions, gaskets, and a self-adhesive drilling template for locating and mounting the detector. The large access door is completely removable to allow fast detector installation and field wiring connections. The 16 gauge steel housing is finish in red bake enamel for easy identification. In addition, five one-gang knockouts on the housing provide a convenient location for mounting intelligent Signature Series modules.

In fact, the Edwards Est SIGA-DH Duct Housing comes with a 6 inch (150 mm) exhaust tube. Furthermore, air sampling tubes are available in lengths from 8 inches (200 mm) to 10 feet (3048 mm) and must be ordered separately. Compatible smoke detectors, mounting bases, and accessories are list in the Ordering Information. Refer to individual device catalog literature pages for more detail.
