Functions
Signal Processing
Uses passive infrared and microwave technologies to
provide an alarm condition when both fields of
protection are simultaneously activated. Alarm signals
must meet the signaling requirements of both
technologies to activate an alarm. Adjustable PIR and
microwave sensitivity.
Microwave Signal Processing
Pattern recognition circuitry identifies and ignores
repetitive false alarm sources. Adaptive processing
adjusts to background disturbances. This helps to
reduce false alarms while maintaining catch
performance.
Motion Analyzer II Processing
Motion Analyzer II uses multiple thresholds and timing
windows to analyze timing, amplitude, duration, and
polarity of signals to make an alarm decision. It will
not alarm on extreme levels of thermal and
illumination disturbances caused by heaters and air
conditioners, hot and cold drafts, sunlight, lightning,
and moving headlights. Provides three sensitivity
settings.
Test Features
Externally visible alarm LED flashes to indicate a
trouble condition.
Draft and Insect Immunity
The sealed optical chamber provides immunity to
drafts and insects.
