AP450 and AP450A Motion Sensors
AP450 Motion Sensors
Models: AP450, AP450A
Installation Instructions
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
•
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.
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 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.
