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.

will be across the detection pattern. See Figure 2 below.
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.
