AP450 Motion Sensors Installation Instructions
Direct sunlight on the sensor
Description
The AP450 sensors (models AP450 and AP450A) are passive infrared motion detectors that are highly sensitive to moving infrared sources. They feature superior immunity to RFI, vibration, static electricity, temperature changes, and other false alarm sources.
The sensors provide jumper-selectable sensitivity, range, and LED settings. The masks included allow the coverage pattern to be modified for a wide variety of applications.
Heat sources in the field of view (heaters, radiators, etc.)
Strong air drafts onto the sensor (fans, air conditioning
etc.)
Large animals (dogs, cats) in a field of view The unit should be mo
unted at a height of 6 to 10 feet (1.8 to
3.0m).
Caution: You must be free of static electricity before handling
sensor circuit boards. Touch a grounded, bare metal surface before touching circuit boards or wear a grounding strap.

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 above.

the screw hole. Pry the cover off the base. See Figure 1 above.
Avoid possible false alarm sources such as:
P/N 1038277 REV C 17MAY11 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 below.
Select mounting holes for corner or wall mounting. Use the
4. base as a template for marking screw hole locations on the wall. See Figure 3 below.
Strip the cable for 2 inches (5cm) and pull it through the
5. cable entry hole(s) and strain relief. Make sure that the cable has slack in the wall. See Figure 3 below.
Use screws and wall anchors, if necessary, to attach the
6. base to the wall.
7. Select the appropriate coverage pattern. See “Selecting the covera
ge pattern” below
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 below.
Strip 1/4 inch (0.6cm) of insulation from each wire. Insert
9. each wire into the appropriate terminal and tighten screws. See Figure 7 on page 3.
10. Set the sensitivity, range and LED jumpers for the application desired. See Figure 7 and “Setting the sensitivit
y, range, and LED” on page 3

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 below.
Mask the appropriate mirror curtains with the adhesive
• labels provided. See the example shown in Figure 5 below. Do not use shar
p 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 presence of objects within 5 feet (1.5m) and directly under the sensor. See Figure 6 on
e 3.

To replace the cover, insert the closing tabs at the bottom
11. 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 on page 1.
