Installation Instructions

Preliminary

Description

The AP450 sensors 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.

Parts

The following parts are included:

• AP450 or AP450A sensor

• Three factory-installed jumpers

• T wo plastic masks

• Sheet of adhesive masking labels

• Cardboard undercrawl window mask

• One screw to secure the housing cover

Selecting a Mounting Location

Install the unit so that the expected movement of an intruder will
be across the detection pattern. See Figure 2.

A void possible false alarm sources such as:

• Direct sunlight on the sensor

• 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 mounted 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. T o 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.
