2.2 Installing door/window magnetic contact
The door/window magnetic contact includes two parts. The sensor
would send the wireless signal to the alarm panel immediately when
the two parts are separated more than 15-30mm.
2.3 Installation of P.I.R.
PIR refers to passive Infra-red sensors. A Passive Infra-red sensor is an
electronic device that detects the motion or movement of human body
by sensing the heat emitted from the body. Detection range is usually
5-12 meters, Horizontal detection angle is 110 degrees, and vertical
detection angle is 40 to 60 degrees. Infrared sensor should be installed
around 2.2 meters over the ground and be aligned to detecting regions.
Adjust the direction and distance to the suitable position and then fix
the sensor on the wall or the furniture. PIR can only be installed in the
room/hall, not face the sunlight and windy. The location of installation
would affect the accuracy of detection.
