Bus PIR / MW motion detector
Code: JA-121PW
A motion detector combining a passive infrared (PIR) sensor and a microwave (MW) sensor. The dual detection increases resistance to false alarms in environments prone to sudden temperature fluctuations, such as air drafts, radiant heating sources, and similar conditions. The standard PIR detector triggers the microwave detection, which either confirms or disproves the presence of motion.
The product is compatible only with control panels JA-102K, JA-103K, JA-107K, or newer.
