A Few Solutions In Fixing Problems Of Glass Break Sensors Triggering False Alarms In Some Challenging Environments!Shock sensors are sometimes used as the main detection device for each individual window it is protecting, while audio discriminators are used as a back-up sensor for several windows in the sensor's range. The shock sensors are applied directly to the glass it is protecting by a special adhesive tape or a suction cup device & it is triggered by vibrations caused by a window being struck. There are glass break sensors sold today that are sensitive enough to trigger an alarm condition when an intruder tries to cut the glass to gain entry.
Audio discriminators are the most popular & most cost effective glass break sensors sold as a single detector is capable of protecting several windows. These glass break sensors are triggered by the acoustical sound wave of breaking glass. Some of these audio sensors are strategically located on a wall to provide maximum coverage for a single sensor. Properly positioned, some sensors can protect a window up to 50 feet or 15 meters away. A different model audio discriminator has a 360 degree pickup pattern & to get the maximum coverage possible these detectors are specifically designed to be mounted on a ceiling. In choosing what model audio sensor will work best, you need to look at how many windows you would like to protect with a single sensor, along with how many different directions the sensor will need to cover. Audio Sensors can repeatedly trigger an alarm condition in certain home environments by mistakenly identifying certain high pitched sounds for the acoustical sound of breaking glass. If you find yourself experiencing such a problem with any glass break detectors in your home, there are a few solutions that can be implemented to fix this false alarm problem. The first thing you need to do is identify what particular sound(s) is causing your sensor to trigger a false alarm. Once you have identified what specific sound in your home is causing your detector to trigger an alarm condition, you may be able to stop the sound from happening or possibly move it outside of the sensor's range. If this would create a problem for you or your family you may want to consider the next solution. The sound(s) in your home that is causing your detector to trigger a false alarm would be the result of certain family activities happening in your home. Due to this fact you may want to consider creating a security zone that will shut down any glass break detectors that you are having a problem with when your home is occupied. When your home is vacant there will be no activities happening inside your home to cause any glass break sensors to trigger false alarms. Audio discriminators are best used as back-up sensors because individual windows should also be protected with magnetic switch sensors. If this is not the case in your home & shutting down a audio sensor will leave certain windows vulnerable, you may want to look at the next & final solution for fixing your false alarm problem. This solution will fix the false alarm problem from audio sensors confusing other high pitched sounds with the acoustical sound of breaking glass. This final solution will cost you some money because any audio sensors that are triggering false alarms will need to be replaced with audio sensors that use dual technology. Dual technology audio discriminators were specifically designed to be used in challenging environments where false alarms are consistently being triggered.
Dual technology glass break sensors use two different technologies that will need to be activated in a precise sequence, before an alarm condition can be triggered. The two technologies used are detecting acoustical sounds of breaking glass & detecting vibrations of low frequency sound pressure waves. A compression wave is caused by the inward flex of a window just prior to it breaking, followed by the acoustical sound of breaking glass. When no compression wave is detected prior to the sound of breaking glass the alarm will not be triggered.
