Tamper-activated test mode: should be tested using the AFT-100 glassbreak simulator
Breaking a window is one of the easiest and most common ways for an intruder to enter a home or business. To help protect against this type of intrusion, a WLS922L-433 Glassbreak Detector is indispensable. "Smart" enough to distinguish the sound of breaking glass from other common sounds found in homes and businesses, the detector features high-performance microphone using Dynamic Signal Processing and can determine all types of breaking framed glass (plate, float, tempered, wired and laminated). Moreover, the WLS922L-433 is provided with an installerselectable Dip Switch with 2 different levels of detection that allow optimising false alarm immunity for certain acoustic environments. All these features make WLS922L-433 Glassbreak Detector a highly reliable and must-have security constituent for your home and business.
Locating the Detector
For optimum protection, the WLS922L-433 should have a direct line of sight to the protected glass. Window coverings will absorb sound from the shattering glass. If this can potentially occur, mount the WLS922L-433 as close as possible to the protected glass, either on an adjacent wall, the ceiling or behind the window covering.
AFT-100 Glassbreak Simulator
The AFT-100 glass-break simulator provides the most reliable and accurate indication of the correct mounting location for the detector. Do not install the detector beyond the maximum recommended range, even if the glass-break simulator reports additional range. Future changes in room acoustics could reduce any additional range. Test for false alarm immunity by creating sounds in the room that will likely occur when the detector is armed.
