AP450 Motion Sensors Installation Instructions

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.

Parts

The following parts are included:

• AP450 or AP450A sensor

• Three factory-installed jumpers

• Two 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 below.

Avoid 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 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.

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

above.
