Open the power switch before using. Installation height is about 2.2 meters above ground and it
should be installed in the corner of the room to get the best detection range and should form a certain
angle with the indoor walking line at the same time (90 degree angle with people walking direction is
best for detection)
Installation:
Take out mounting bracket; press the bracket to the slot in the sensor bottom. Find the base and
reinforce it with two screws in the wall. Press the PIR with bracket into the center hole of base. and
then adjust the best angle of detecting. (This method is suitable for project installation)
Attention:

2. Within coverage of detection, there should be no any big objects for obstruction.
3. There should be no two infrared sensors in the same space as they will possibly intervene with
each other.
4. Avoid facing window, cooling or warming machines, stoves, or other appliances that cause the
