DUET - Professional dual technology detector

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.
DUET-ST memorizes and stores the tripping order of alarm occurrences for up to 14 arm/disarm periods. This provides vital information. If either technology is blocked, masked or malfunctioning, the trouble output is activated
