Power saving feature
The PIR goes to power save mode after about 1 minute to save
power.
After transmitting a detected movement, the PIR will not retransmit
for 1 minute; any movement detected during this period will extend
the power save time by another minute. This way; continuous
movement in front of a PIR will not unduly exhaust the battery
7. Setting PIR sensitivity
You can set the PIR’s detection sensitivity as follows:
 To increase detection sensitivity, set the jumper to ON (factory
default).
 To maintain the normal detection sensitivity, set the jumper to
OFF.
8. Find a suitable location
Follow all steps in this section to install the sensor.
Decide on the location of the PIR and if it is to be corner or surface
mounted. Take the following requirements and restrictions into
account when choosing a suitable location for the sensor.
Suitable location: recommendations
 Mount the detector at a height of 1.9 m ~ 2 m for best
performance.
 The PIR is designed to give a
typical detection range of 12
meters when mounted at 2
meters above the ground.
 When mounted at 1.9 meters
above the ground, it gives a
typical pet immune range of 7
meters.
 The higher the PIR is mounted
from the ground, the further its pet immune range will reach.
 Sensor performance is affected by external factors such as height
of detected object, desired detection range, installation area, etc.
The suggested mounting height could be adjusted according to
actual installation environment factors.
