1 INTRODUCTION
Congratulations on your selection of the DSC WLS900 Wireless Security System. The WLS900 Wireless
Security System has been designed to provide you with a dependable and flexible security system that is
easy to operate and maintain. The system uses radio signals to link its components together. Wireless
technology allows for great flexibility in locating the system’s components; only the controller and the
sounders need to be located where they can be plugged into an electrical outlet.
Each of the system’s components is designed to perform a specific function within the security system.
The Keypad is the part of the system you will be using the most; it is used to arm and disarm the
system, and to display messages about system operation. The keypad screen displays messages in
plain language to tell you what the system is doing, and to guide you through system operation.
The Controller contains the electronics that control the security system. When an alarm is generated, the
controller will activate the Sounder and will, if programmed to do so, contact your monitoring station to
report the alarm. The controller can be located anywhere a telephone line connection and an electrical
outlet is available. Along with its electrical transformer, the controller also has a rechargeable backup
battery that will operate the system should there be a power failure.
The Sounder is used to alert you when an alarm has occurred. The sounder is also used to indicate
with various sounds that certain system activities are being performed. The sounder should be located
centrally so that it may be heard clearly when it is activated. The sounder requires an electrical outlet
for its transformer.
Motion detectors are designed to detect the movements of an intruder. Motion detectors will generate
an alarm if they detect motion when the system is armed. Care should be taken not to block the view of
your motion detectors. If you can't see them they can't see the intrudor. Your installer will tell you where
motion detectors have been installed and what areas they protect.
Door or Window Sensors are used to indicate when a door has been opened. If a door or window
sensor is activated when the system is armed, an alarm will sound. A sensor can also be set by your
installer to have “entry/exit delays”. These delays allow time for you to activate a sensor when entering
or leaving the premises without causing an alarm. Your installer will tell you where door or window
sensors have been installed, and which sensors have these delays.
Smoke Detectors sound an alarm when smoke from a fire is detected. The fire detection part of your
security system is designed to provide you with an early warning of a possibly dangerous situation; your
installer will explain to you how your fire detection system works and how it should be maintained. For

information about life safety devices and where they should be located.
Test Your System Regularly
To ensure that your system continues to function as intended, it is important that you test your system
regularly. Refer to “Walk Testing Your System” in the Master Codes section of this manual, and read and
follow the instructions carefully. If your system does not function properly or if you have any questions
about testing your system, call your installer for service or assistance.
Important Notice
A security system cannot prevent emergencies. It is only intended to alert you of an emergency
situation. Security systems are generally very reliable but they may not work under all conditions
and they are not a substitute for prudent security practices or life and property insurance. Your
security system should be installed and serviced by qualified security professionals who should
inform you of the level of protection that has been provided, and instruct you on system operations.
