The DS1100i Detector Series uses microprocessor-based sound analysis technology (SAT) to listen for the specific frequencies associated with breaking glass. The DS1101i can be used to detect breakage of plate, tempered, laminated and wired glass types. A built-in environmental test feature alerts the installer to false alarm hazards in harsh environments. The round detectors mount on the ceiling or walls.

Glassbreak detectors are intended only as a component of a perimeter protection system.
They should always be used in conjunction with motion sensors.
Mounting
Mount the DS1101i series detectors on the ceiling, or on the wall opposite or adjacent to the window.
Coverage depends on room acoustics and window size.
