Premier Impaq Glass Break

Digital Signal Analysis

The Impaq Glass Break is an acoustic glass break detector designed to provide the earliest possible warning of a potential intruder by detecting the sound of breaking glass. An advanced microprocessor analyses signals digitally, processing information relating to the frequency, amplitude and timing of every sound. For maximum false alarm immunity four separate frequency bands are analysed (Quad Frequency Analysis). The Impaq Glass Break will only indicate an alarm if the signals exactly match those of a window being broken.

Digital Flex Detection

False alarm immunity is further enhanced by the use of Digital Flex Detection. This detects the low frequency pressure wave transmitted when a window is struck. An alarm signal will only be generated if a flex signal is detected, followed immediately by the shatter signal. This ensures common false alarm sources (e.g. a glass bottle breaking outside) are completely ignored.

Glass Type Selection
Different types of glass produce different acoustic responses when broken. The Impaq Glass Break features a selector switch which can be set to either Plate and Tempered or Laminated and Wired glass types.

Dual LED Indication

Dual green and red LEDs simplify set up and help reduce false alarms by indicating pre-alarm signals and providing confirmation that test mode has been initiated.

Enhanced Adjustable Coverage Pattern

The Impaq Glass Break can be mounted on walls, in corners or on ceilings for maximum flexibility. With a coverage angle of 170 �at distances of up to 9m, protecting several windows with one detector is fast and straight forward. Sensitivity is fully adjustable allowing each detector to be optimised for its environment.
