u Motion Analyzer II processing
u Motion Monitor
The wall mount DS935Z and ZX935Z PIR Detectors use
Motion Analyzer II signal processing to reduce false
alarms. Several unique test features, including Motion
Monitor, provide coverage integrity. The detectors'
optics, coverage patterns, and mounting options
provide installation flexibility.
Functions
Signal 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 or illumination
disturbances caused by heaters and air conditioners,
hot and cold drafts, sunlight, lightning, and moving
headlights. Two sensitivity settings are provided.
Supervision
• PIR supervision: Provides trouble output in the event
that PIR circuitry fails.
u Self-test supervision systems
u Field replaceable, pointable mirrored optics
u Four coverage patterns
• Motion Monitor: Switch-selectable four or 30 day
Motion Monitor supervision timers provide the
detector with the ability to verify that there is a clear
view of the protection area and that it has not been
blocked.
Draft and Insect Immunity
The sealed optical chamber provides immunity to
drafts and insects.
