DS1100i Detector Series uses microprocessorbased sound analysis technology (SAT) to listen for the specific frequencies associated with breaking glass. The DS1101i, DS1101i‑BEL, DS1101i‑CHI, and DS1101i‑FRA 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.
Audio signals are analyzed using microprocessor-based SAT and must produce specific frequency, signature, and timing relationships to cause an alarm. The sophistication of this processing technique ensures proper catch performance while eliminating false alarms.
The magnet‑operated test mode provides a location verification and operational test when using the optional DS1110i Glassbreak Tester. The test mode also includes an environmental test that alerts the installer to possible false alarm sources caused by ambient noise. The automatic sound check feature allows the end user to verify that the detector is powered and functioning by clapping his hands. An externally‑visible alarm LED indicates an alarm or test condition and can be programmed to latch if desired.
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.
