How to install the wireless PIR motion detector
Passive Infrared (PIR) Motion Detectors protect space by 'looking' for changes in infrared (heat) energy levels caused by movement of an intruder. The passive infrared detectors are passive devices. i.e., they do not transmit any form of energy. When a person enters and moves within the detecting zone, his body which is at its normal temperature of 98.6 degree F., radiates more (or less) thermal energy than the surroundings and such minute difference in thermal energy is detected by the PIR. In simple words, PIR keeps a picture of the heat levels in its view and keeps on comparing the new view with the stored one. In case there is any change then they activate the alarm.
- Fix the bracket on suitable wall surface or in wall corner at a distance of 2~2.4m above the ground;
Open the sensor shell to connect the batteries well and adjust jumper line (short circuit “5S”: The sensor will detect once every 5 seconds; short circuit “5MIN”: The sensor will detect once every 5 minutes;
short circuit “5S” for testing and “5MIN” for normal use;Fix the sensor onto the bracket;
Adjust the sensor to a proper angle and then slide the power switch on the side to “ON”, and it will enter into the
normal working state after 30 seconds;
Upon the working light flashes frequently in green, please replace the batteries.
