Microprocessor-based sound analysis technology (SAT)
Automatic environmental test circuitry
Sound check
The 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
