The WLS912L is a battery-operated glassbreak sensor, designed to detect the sound produced by the shattering of framed glass. Equipped with an RF transmitter, the WLS912L establishes a supervised, one–way communications link with the system controller. The WLS912L uses Dynamic Signal Processing to provide accurate detection of plate, laminated, wired and tempered glass types, while rejecting common false alarm sounds.
