Condition: New
Brand: Edwards, EST
Status: Active
SKU: 113786
Manufacturer Part #: SIGA-SDH


The SIGA-SDH(R) 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 analyzes 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. Each duct housing is 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 finished in red baked enamel for easy identification. Five knockouts on the housing provide a convenient location for mounting intelligent Signature Series modules.
