u Motion Analyzer II processing
u Motion Monitor
These ceiling mount, 18 m (60 ft) panoramic PIR Detectors use Motion Analyzer II processing to reduce false alarms. The series consists of the:
• DS938Z Panoramic Detector
• ZX938Z Panoramic Detector with POPIT
Several unique self-test features, including Motion Monitor, provide coverage integrity. Field replaceable mirrored optics allow them to be mounted on ceilings from 2.5 m to 6 m (8 ft to 18 ft) in height.
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 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. Provides three sensitivity settings.
PIR Supervision
PIR supervision provides trouble output in the event that PIR circuitry fails.
u Changeable mirrors
u 360° x 18 m (60 ft) diameter pattern
Motion Monitor
Switch-selectable four or thirty 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.
Test Features
Three externally visible high output alarm LEDs visible from any angle, flash to indicate trouble condition. Internal noise voltage test pins provide precise pattern location and background disturbance evaluation using a standard analog meter.
Certifications and approvals
These detectors have also been designed to meet the requirements of:
