Each WLS904 motion detector should be located so that it provides
optimal coverage of the intended area. Refer to Changing Motion Detector
Lenses below for information on the four lenses available for the WLS904
Motion Detector. When locating motion detectors, observe the following:

• For the Wall-to-Wall, Corridor and Curtain Lenses, the Mounting Height

should be 6-10 ft./ 2-3 m from the floor. The nominal mounting height is
7.5 ft./ 2.3 m.

• For the Pet Alley Lens only, the Mounting Height should be 4-5 ft./1.2-1.5m

from the floor.

• Do not aim the detector at reflective surfaces such as mirrors or

windows. This may distort the coverage pattern or reflect sunlight
directly onto the detector. Avoid locations where the detector may be
exposed to direct or reflected sunlight.

• Avoid locations that are subject to direct air flow, such as near an air duct outlet.

• Do not locate the detector near sources of steam or oil vapor, such as

a stove or fryer.

• Do not obscure the Detector’s coverage pattern with large objects within

the detection area. If you can’t see the detector, it can’t see you.

• For indoor use only

• Dead zone 6”/15 cm

NOTE: No detector should be mounted without first performing a
module placement test to determine that it is in range of the
wireless receiver. See the Placement Test instructions in the
Instruction Sheet for your receiver, or in the installation manual for
your system.

When a location has been determined,
remove the plastic from the mounting
holes and locate the backplate on the
wall and mark screw locations. It is
suggested that wall anchors be used for
all screw locations. Secure the backplate
to the wall, and then secure the enrolled
Detector to its backplate.

Battery Installation

This system is designed to work with Eveready Alkaline Energizer
Batteries. 

Do not install any other type. The reliability of the security

system depends on its batteries, and “no name” or generic brand
batteries may not provide the best quality and dependability.

• Use fresh batteries. Most batteries have a “best before” date printed on

their packaging or on the batteries themselves. Buy batteries that have a
“best before” date of two years or more from your purchase date.

• 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.

Remove the motion detector from its
mounting plate by holding the sensor by
its sides and pushing up. Install four
fresh Eveready Alkaline Energizer AAA
batteries. Be sure to insert the batteries
in the proper orientation. Replace the
sensor on its mounting plate, making
sure it snaps into place.

After all the batteries are installed, the detector will take 60 seconds to warm
up. During this time the LED will flash slowly.
