Indoor PIR Motion Detectors 
Visonic Inc. Access and Security Products Visonic DUET Professional dual technology Motion detector DUET

FEATURES :

* Advanced signal processing * Separate diagnostic indicators for PIR and microwave * Selectable alternate polarity pulse counter * Temperature compensation * State-of-the-art DRO microwave technology * Superior fluorescent light and RFI noise filtering * Alarm order retained in memory * Trouble analysis indication and output * Look-down creep zone protection

DESCRIPTION

DUET combines innovative microwave technology with advanced PIR detection. The creep zone directly under DUET provides anti-sabotage protection. DUET employs signal processing technology using digital algorithms to differentiate real-motion signals from noise signals. A digital multiple "notch" filtering technique eliminate these interferences.
