The ZoDIAC Digital Quad

The ZoDIAC Digital Quad has all the advantages of the ZoDIAC Digital PIR, with the addition of a real quad element sensor that provides added catch performance and false alarm immunity in homes that are susceptible to false alarm hazards.

The quad element means that the same signal has to be seen twice in quick succession by the sensor in order to trigger an alarm.

This special feature assures significantly reduced false alarms from such sources as warm air from heating systems, moving curtains on open windows and spot temperature changes.
