Bosch OD850-F1 50' X 50' Outdoor Tritech Motion Detector
The OD850 Series TriTech detectors are for use outdoors and in other harsh environments. They use a combination of passive- infrared (PIR) and microwave detection with advanced signal processing.The detectors process PIR signals with Motion Analyzer II signal processing and microwave signals with Linear Travel Distance (LTD) signal processing. The detectors can distinguish between small, repetitive motions such as tree limbs moving in the wind and the more purposeful motions of intruders. These advanced processing techniques and the detectors' mechanical design combine to provide superior performance in a wide range of weather conditions.
Motion Analyzer II Processing
This PIR signal processor uses multiple thresholds and timing windows to analyze timing, amplitude, duration, and polarity of signals to make an alarm decision. Extreme levels of thermal and illumination disturbances caused by hot and cold drafts, sunlight, or lightning do not cause an alarm.

LTD Microwave Signal Processing
This microwave signal processor measures the linear travel distance of a target to make an alarm decision. It eliminates alarms for objects that move but do not travel, such as tree limbs and hanging signs.
Two Sensitivity Levels
The detectors have two user-selectable PIR sensitivity settings:
Standard sensitivity is the recommended setting for a minimum of false alarms. The detector tolerates environment extremes on this setting.
Intermediate sensitivity is the recommended setting for any location where an intruder is expected to cover only a small portion of the protected area. The detector tolerates normal environments on this setting. This setting identifies intruders more quickly, but may produce more false alarms.
Adjustable Timed Relay Output
In addition to an alarm relay, there is a Form C, unsupervised, timed relay contact that alternates state 1 sec after an alarm and follows a user-selectable timer. The time expires at the set time after the last alarm (it resets on each new alarm).
