Glass Break Detectors

Magnetic sensors may not detect a break-in if the thief simply smashes a window or a glass door. Our acoustic glass breakage detectors respond to the actual cracking of the glass the moment someone tries to break in. The alarm will sound while the thief is still outside – not after he is already walking around inside the home.

Glass break detectors fall into two general categoris – Acoustic and Shock sensors. Acoustic detectors protect all of the windows in a room or area. Shock detectors protect a single expanse of glass.

  • Acoustic Sensors – Acoustic glassbreak sensors are an important part of an effective perimeter detection system. It is very important to choose the right sensor for a particular application or environment. We offer you a variety of choices for virtually any glassbreak application.

  • Shock Sensors – Breaking glass produces specific shock frequencies that travel through glass and window frames. When shock sensors feel the wave generated by breaking glass, they signal an alarm. These sensors mount directly on the glass or the frame and give you a product virtually immune to false alarms. Shock sensors can operate on windows with heavy drapes or shutters and they help prevent break-in attempts by providing a visual deterrent to intruders.

FG-730 Glassbreak Detector - IntelliSense

IntelliSense’s FlexGuard® FG-730 incorporates the most reliable, field-proven technology available – setting the industry standard in glassbreak detectors.

Features
  • Field Proven Design - The world’s best selling glassbreak detector.
  • Dual Technology Flex-Audio Principle - Positively detects and confirms breaking glass by analyzing both "flex" (impact) and "audio" (shattering) frequencies. For an alarm to occur the flex signal must be followed by an audio signal within a prescribed time frame.
  • Signal Verification - Both flex and audio signals must register valid amplitude, duration and frequency for an alarm to occur.
  • Signal Filtering - Thorough filtering and processing of all signals provides greater immunity to false alarms.
  • Broad Range - Detects glass breakage from distances up to 30' (9 m). The FlexGuard FG-730 detector sets the industry standard in glassbreak detectors.
  • Dual Flex/Audio Technology - Provides excellent catch performance while virtually eliminating false alarms.
  • Indicator LEDs - LED alarm indicator for testing flex and audio technologies.
  • Burst Rejection Circuit - Ignores short flex/audio noise burst signals present in some environments.
  • Circuit Protection - Prevents shorts, overloads and reverse-polarity connections from causing damage.
  • Alarm Memory - Alarm LED can be set to latch upon alarm; helps identify which unit alarmed in multiple detector applications.
  • RFI Immunity - 100 watts at 3m (10') from all mobile bands 27–1000 MHz.
  • Easy Installation and Set-Up - Mount within 9m (30') of the glass to be protected. (Can be adjusted to suit characteristics of each location.)
  • Low Voltage Operationv10–14VDC
  • Low Current Draw - 25mA at 12VDC
