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.

Supervised Microwave and PIR

Patented fully supervised microwave and PIR circuitry
provides single technology coverage in the event the
microwave subsystem fails.

Pet Immunity

The detector is able to distinguish between signals
caused by humans and signals caused by pets [one
dog up to 45 kg (100 lbs.), two dogs up to 27 kg
(60 lbs.), or up to ten cats]. This provides immunity to
false alarms while maintaining proper catch
performance of human targets.

Temperature Compensation

The sensor provides compensation at critical
temperatures.
