Microprocessor-based sound analysis technology (SAT)
Automatic environmental test circuitry
Sound check
The DS1102i Detector Series uses microprocessorbased sound analysis technology (SAT) to listen for
the specific frequencies associated with breaking
glass. The DS1102i and DS1102i‑CHI 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 square detectors mount on ceilings
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.
