glassbreak theory basics

Glassbreak Theory Basics

How does an acoustic glassbreak work?

flex signal




Flex Signal
  • Very low frequency sound
  • Results from glass vibrating upon impact
  • Similar to a drum head vibration

Audio Signal




  • Mid- to High-frequency sound
  • Results from glass shattering
installation basics
Installation Basics
  • Never exceed max range (25ft)
  • Mount on opposite wall or ceiling
  • Install at least 6 ft from floor (to avoid blockage by furniture,etc.)
installation basics1
Installation Basics
  • Always mount the sensor in direct line of site to the glass…
  • e.g….an imaginary string tied to the detector should reach all points of the glass without bending.
  • Always use the Tester for every installation
installation basics selecting the location
Installation BasicsSelecting the Location
  • Clear view of glass to be protected
  • At least 6.5 feet above floor
  • At least 3.5 feet from forced air ducts
  • At least 3.5 feet from sirens or bells
  • Between the window and any heavy protective window coverings
installation basics locations to avoid mounting
Installation BasicsLocations to Avoid Mounting
  • A corner
  • On the same wall as the protected glass
  • On free-standing pillars or posts
  • In rooms with noisy equipment such as air compressors, bells, power equipment if the equipment will be operating while the sensor is armed
introducing the fg 1525 glassbreak detector
Introducing the FG-1525Glassbreak Detector
  • FlexCore Signal Processing
  • 25ft maximum range
  • Adjustable sensitivity
  • No minimum range
  • Remote Test Mode Enable with FG-701
  • Protected PCB in all models

FlexCore Signal Processing

  • Parallel multiple tasking
  • Faster than sequential processing (micro)
  • Extracts over 50% more data in same time
  • Faster, more accurate false alarm rejection

Installation BasicsSensitivity Settings
installation basics sensitivity settings1
Installation BasicsSensitivity Settings
  • Mount the detector
  • Start on Minimum sensitivity
  • Test range using FG-701 simulator
  • Adjust sensor sensitivity as needed
  • Re-test range using FG-701 simulator
installation basics using remote test mode
Installation BasicsUsing Remote Test Mode
  • Set FG-701 to “Activate” and “Man”
  • Press “Red” button
  • The “buzz” signal starts Test Mode
  • Green LED will flash
installation basics testing
Installation BasicsTesting
  • Set FG-701 to “Test” and “Flex”
  • Position tester near the glass
  • Press “Red” button to prime the tester …
installation basics testing1
Installation BasicsTesting
  • Aim FG-701 directly at detector
  • Strike glass with cushioned tool (Flex signal)
  • Tester will generate “Audio” signal
  • Detector’s “Red” LED will light for successful test

Types of Glass Covered

  • UL and ULC Listed for:
    • Plate Glass
    • Tempered Glass
    • Laminated Glass
    • Wired Glass
    • Coated Glass
    • Double Pane Sealed Insulated Glass
