WLS912L
Glassbreak Detector
INSTALLATION INSTRUCTIONS
The WLS912L is a battery-operated glassbreak sensor, designed to detect the
sound produced by the shattering of framed glass. Equipped with an RF transmit-
ter, 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.

printed on the batteries. Many cities and communities have collection sites or
