Long Range PIR Detectors
Features
▶ Motion Analyzer II processing
▶ Motion Monitor
▶ PIR supervision
▶ Self test supervision systems
▶ Field-replaceable optics
▶ Three coverage patterns
The surface or corner mount, long-range DS794Z and
ZX794Z Series PIR Detectors use Motion Analyzer II signal
processing to reduce false alarms. Several unique test
features, including Motion Monitor, provide coverage
integrity. Field replaceable mirrored optics and three
different coverage patterns 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 and illumination
disturbances caused by heaters and air conditioners, hot
and cold drafts, sunlight, lightning, and moving headlights.
Three sensitivity settings are provided.
Test Features
External visible alarm LED flashes to indicate trouble
condition. Internal Noise Voltage Test Pins provide precise
pattern location and background disturbance evaluation
using a standard analog meter. Internal sounder output for
use with Sonalert
® sounder (not supplied).
Motion Monitor
Switch-selectable four and thirty day timers verify that there
is a clear view of the protection area.
PIR Supervision
Provides trouble output in the event that PIR circuitry fails.
