Intelligent Duct Smoke Detector Housing GSA-DH

Manufacture: kidde
Product code: GSA-DH

The GSA-DH Duct Smoke Detector Housing ⭐
✅ is specially engineered to exploit all the capabilities of Signature Series intelligent photoelectric and multisensor smoke detectors ⭐
✅ Kidde Signature Series detectors gather analog information each of their one or more sensing elements and converts it 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.
