Installation of bracket and battery
In order to install and adjust conveniently, we provide bracket. You should fix the bracket with screws on the position that has been selected first before use. And then install the battery into the PIR. It will enter into normal working status in five minutes.
Selection the position of installation
The position should be in the monitored areas. The height of installation is about 2.1m, relative to the alarm area of PIR. In order to avoid wrong alarm in the largest limit, we should notice whether it is day or night, avoid a direct ray of light on the PIR. PIR works on the condition of inducing the infrared light of moving objects and infrared energy's difference of background objects.To acquire the largest sensitivity, we suggest that the PIR should fix forward to the lowest temperature position of guarding area.
