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.
