Mounting the Sensor
1. To remove the cover plate, insert a flat-bladed screwdriver
between the notch on the top of the cover plate and the
cover. Pry up the cover plate. See Figure 1.
2. Remove the housing screw that holds the cover to the
base, insert a flat-bladed screwdriver into the slot above
the screw hole. Pry the cover off the base. See
Figure 1.
3. Pull up on the top edge of the electronics module while
rocking down on the lower edge to remove the module
from the base. Be careful not to touch the pyroelectric
sensor located on the bottom of the module. See Figure 3.
4. Select mounting holes for corner or wall mounting. Use
the base as a template for marking screw hole locations
on the wall. See Figure 3.
5. Strip the cable for 2 inches (5cm) and pull it through the
cable entry hole(s) and strain relief. Make sure that the
cable has slack in the wall. See Figure 3.
6. Use screws and wall anchors, if necessary, to attach the
base to the wall.
7. Select the appropriate coverage pattern. See Selecting the
Coverage Pattern.
8. Replace the electronics module by lining up the notches
on the module with the module notch guides and press
the top of the module down until it snaps into the module
guides. See Figure 3.
9. Strip 1/4 inch (0.6cm) of insulation from each wire. Insert
each wire into the appropriate terminal and tighten
screws. See Figure 7.
10. Set the sensitivity, range and LED jumpers for the
application desired. See Figure 7 and Setting the
Sensitivity, Range and LED.
11. To replace the cover, insert the closing tabs at the bottom
of the cover into the guides at the bottom of the base and
snap the cover down. Insert the screw. Fit the hole in the
cover plate over the LED and snap the cover plate into
place. See Figure 1.

Selecting the Coverage Pattern
The coverage pattern for the unit can be modified to fit specific
applications by masking off mirror curtains. Curtains should be
masked to avoid sources of false alarms, such as heaters, air
conditioners, and windows.
If necessary, use one or more of the following methods to
modify the coverage pattern:
• Use one or both of the plastic masks provided to mask off
large areas of coverage as shown in Figure 4.
• Mask the appropriate mirror curtains with the adhesive
labels provided. See the example shown in Figure 5. Do
not use sharp objects to remove unwanted labels. If
necessary, carefully peel the label off.
• Use the cardboard undercrawl window mask to improve
false alarm immunity in the presense of objects within 5
feet (1.5m) and directly under the sensor. See Figure 6.
