PASSIVE INFRARED DETECTOR
The highly accurate and reliable detection pattern will
maintain its sensitivity throughout the entire detection area
even in high temperature or low contrast environments.
Quad Zone Logic creates an extremely high vertical zone
density, two or three times the size of conventional PIRs.
These taller zones capture the entire body mass and enable
detection of even the smallest temperature contrast against
the temperature of the background. In addition, the vertical
detection density has been improved to take into account
dead zones created by furniture or partitions.
