LifeSOS PIR-3SP Manual

INTRODUCTION

The PIR-3SP Passive Infrared Detector detects the movement of human body heat within its effective
coverage; thus, when an intruder crosses or enters the area, the resulting change in infrared energy
from the intruder will be detected and an alarm signal will transmit to the Base Unit.

PET IMMUNE DETECTOR

This detector is immune to one domestic pet up to 18 kg or 60 cm moving on the floor.
If animal activity takes place above 1 meter high, the pet immunity allowance will be significantly
reduced. Therefore Do Not aim the detector at stairways that animal can pass.
This detector should be mounted on the wall or corner at 2.0 m high and perpendicular to the
floor. Please note under this condition, the human motion within 1 m from the detector is
undetectable.
Do NOT use any mounting bracket with swivel adjustment. Should you must use a bracket, it
should be used for horizontal alignment only, do not tilt down.
Place the PCB at the "0" scale position. (for PCB version ST-IR-3B, or "P" scale for ST-IR-3A).
And jumper JP5 at "PET" position.
It's a must to verify the pet immune function after installation. In case animal is detected, sliding
the PCB to +1~+2 scale to test again (for PCB version ST-IR-3B, or to -1~0 scale for ST-IR-3A).
The weight of the animal can only be used as a reference. Other factors such as height and color
of fur could also affect the level of immunity.

To get the best sensitivity, PIR should be mounted to detect
movement of the intruder across a room rather than toward the
detector.
