I N S T R U C T I O N S
The WLS912 is a battery-operated glassbreak sensor. It is designed to detect the sound pro-
duced by the shattering of framed glass. Equipped with an RF transmitter, the WLS912 estab-
lishes a supervised, one–way communications link with the system controller.
The WLS912 uses Dynamic Signal Processing* to provide accurate detection of the breaking
of framed plate, laminated, wired and tempered glass types, while rejecting common false
alarm sounds.

Battery Guidelines and Installation
Before installing batteries, please note the following guidelines:
•
The detector is designed to work with Eveready Alkaline Energizer "AA" batteries.
Do not install any other type. "No-name" or generic brand batteries may not
provide the best quality and dependability.
•
Always replace all three batteries at the same time.
•
When disposing of used batteries, follow the instructions and precautions printed
on the batteries. Many cities and communities have collection sites or services for
used household batteries. Contact your municipal offices for information on the
disposal of used batteries.
To install batteries:
1.
Remove the detector from its mounting plate:
If unmounted, hold the detector by its sides and push down on
the top end of the mounting plate, as shown at right.
