Motion Detector

DUAL ELEMENT PET IMM PASSIVE IR MOTION DETECTOR/TAMPERFORMC

PRO SERIES DUAL DETECTOR

The Bosch DS938Z is a ceiling-mount, 360 degree passive infrared intrusion detectors that uses Motion Analyzer II to reduce false alarms. The DS938Z is equipped with advanced PIR detection and supervision circuits and is designed to provide an alarm condition upon detection of an intruder passing through its area of coverage. Motion Analyzer II uses multiple thresholds and timing windows to analyze timing, amplitude, duration, and polarity of signals to make an alarm decision, Three PIR sensitivity settings are available. Several unique self-test features, including Motion Monitor, provide coverage integrity. The DS938Z's field replaceable mirrored optics allow it to be mounted on ceilings from 8 ft. to 18 ft. (2.4 m to 5.5 m in height).

The Bosch DS9370 Series can be used on ceilings as high as 25 ft. (7.6 m). The combination of passive-infrared (PIR) detection, microwave detection, and advanced signal processing techniques allows TriTech detectors to rapidly respond to human targets without triggering false alarms from other sources. With three separate PIR sections that are fully adjustable, the DS9370 Series's coverage can be customized for specific areas at all mounting heights.
