The SIGA-SDH Duct Smoke Detector Housing is specially engineered to exploit all the capabilities of Signature Series intelligent photoelectric and multisensor smoke detectors.
EDWARDS Signature Series detectors gather analog information from each of their one or more sensing elements and converts it into digital signals. The detector’s onboard microprocessor measures and analyses these signals. It compares them to historical readings, time patterns and known characteristics to make an alarm decision. Digital filters and complex Algorithms are applied for optimum detector accuracy. Unwanted alarms are virtually eliminated.
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 finished in red baked enamel for easy identification. Five knockouts on the housing provide a convenient location for mounting intelligent Signature Series modules.
The SIGA-SDH(R) Duct Housing comes with a 150 mm exhaust tube. Air sampling tubes are available in lengths from 200 mm to 3048 mm and must be ordered separately. Compatible smoke detectors and accessories are listed in the Ordering Information. Refer to individual device catalog literature pages for more detail.
