Passive Infrared Readers (PIRs) (
Part # 300302;
Figure 5.1
) are sensitive to changes in infrared
energy caused by an object moving across a
PIR’s field of view. Detection depends on the
difference between the infrared energy
trasmitted by the moving object and the
temperature of background objects.
The PIR Accutech provides ( DSC Bravo Series )
is for indoor use only. Its intended use is to
detect movement through doors, corridors, and
passageways. The relay contacts provided by the
PIR (which control detect validation) can be set
to trigger on programmable timer between a
duration of 1 to 7 seconds.
A typical use for a PIR is a hallway, where there
is no door to mount a Magnetic Switch to, or an
elevator, where placing anything on the door or
frame of the car might be undesirable.
