change in infrared energy is quick enough, the PIR can trigger an alarm. The same applies
if the PIR area includes a window, even though the pattern of protection cannot “see”
through glass. Lights from a passing car can also pass through the window at night and
shine directly into the PIR’s lens.
•
Heating and air conditioning ducts are also important because if they blow air onto an
object within the field of the PIR’s view, the temperature of that object could change
quickly enough for the PIR to “see” a change in infrared energy. PIR’s cannot see air
current, only the change in temperature of a physical object.
•
The PIR senses change in temperature. However, as the ambient temperature of the
protected area approaches the temperature range of 95° to 120° F, the detection
performance of the PIR decreases.
•
Ensure that the area you wish the PIR to cover is free of obstructions (for example,
curtains, screens, plants, and so on.) that may block the pattern of coverage.
•
Anything that can sway or move due to air current can cause a change in infrared energy
within the fields of view. Drafts from doors or windows can cause this to happen. Plants,
balloons, curtains, and hanging baskets should never be left in the PIR’s field of view.
•
Do not mount the PIR on a surface that allows for any vibration. Vibrations not only cause
the PIR to move a little, but it also causes the fields of view in a room to move with
respect the PIR. A little vibration can cause havoc with the PIR’s field of view, thus the PIR
may see a change in energy and trigger the alarm.
•
An installation often requires that the PIR is aimed at the door. The PIR may detect door
movement before the door contact can initiate an entry delay, causing the alarm to
trigger. If you install the PIR facing a door, then while programming the PIR, choose an
appropriate sensor/zone type.
•
The PIR ONLY detects intrusion within the pattern of coverage.
•
The PIR does not provide volumetric area protection.
•
The PIR creates multiple beams of protection. Intrusion can only be detected in
unobstructed areas covered by those beams.
•
The PIR cannot detect motion or intrusion that occurs behind walls, ceilings, floors, closed
doors, partitions, glass doors, or windows.
•
Tampering with, masking, painting, or spraying of any material on the PIR lens or any part
of the optical system can impair detection ability.
•
The PIR, like other electrical devices, are subject to component failure. Even though the
PIR is designed to last as long as 10 years, the electronic components are subject to
failure.
