The ZX776Z PIR Intrusion Detector uses Motion Analyzer II signal processing to reduce false alarms. The detector's internally pointable mirrors and three coverage patterns provide installation flexibility. The ZX776Z includes an internal POPIT for addressable alarm and trouble signaling while communicating on the Zonex bus.
Functions
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 tolerates extreme levels of heat and light disturbances caused by heaters, air conditioners, hot and cold drafts, sunlight, lightning, and moving headlights
Motion Monitor Supervision
Confirms the detector has a clear view of the detection area. The Zonex Bus indicates a trouble condition and the LED pulses if the detector has not alarmed at least once during a selected time period
Insect and Draft Immunity
The sealed optical chamber provides immunity to drafts and insects.
PIR Supervision
PIR operation is checked electronically approximately every 12 hours. If the circuit fails, the LED pulses four times and the trouble output is indicated through the Zonex bus
Test Pins
Internal noise voltage test pins provide precise pattern location and background disturbance evaluation using a standard analog meter.
