The DS1103i Detector uses microprocessor-based
sound analysis technology (SAT) to listen for the
specific frequencies associated with breaking glass.
The DS1103i 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 rectangular
enclosure mounts flush 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 magne‑ 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 DS1103i detector on the ceiling, or on the
wall opposite or adjacent to the window. Coverage
depends on room acoustics and window size.
