Bosch DS1109I Glassbreak Tester

The DS1109i Detector uses microprocessor-based sound analysis technology (SAT) to listen for the specific frequencies associated with breaking glass. It can be used to detect breakage of plate, tempered, laminated and wired glass types. A built-in environmental test feature alerts the installer of false alarm hazards in harsh environments. It is specially designed to mount on door or window frames. A built- in magnetic contact allows monitoring of a door or window opening.

Key Features:

  • Mounts to door or window frames. Includes an internal magnetic contact.
  • Microprocessor-based SAT
  • Automatic environmental test circuitry
  • Built-in door or window contact
Signal Processing

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 insures proper catch performance while eliminating false alarms.

Test Features

The push button operated test mode provides a location verification and operational test when using the optional DS1110i glassbreak tester. Test mode also includes an environmental test that alerts the installer to possible false alarm sources caused by ambient noise. Automatic sound check feature allows the end user to verify that the detector is powered and functioning by clapping his hands. Externally visible alarm LED indicates an alarm or test condition and can be programmed to latch if desired.

Notice: Glassbreak detectors are intended only as a component of a perimeter protection system. They should always be used in conjunction with motion sensors.
