The RX40 Passive Infra Red Sensor uses the Quad Zone Logic for accurate detection of humans.
It is designed to give extremely high false alarm protection by detecting temperature changes.
The RX40 uses taller detection zones divided into upper and lower areas, it then detects the” changes of IR energy in both of the areas and then couple them to give an accurate detection. This enables the RX40 to offer a high reliability in hostile areas.
