u Motion Analyzer II processing

u Motion Monitor

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.
