The Bosch outdoor PIR OD850 is a TriTech motion detectors used for outdoors and in other harsh environments with two sensitivity setting, timed relay output adjustable for two sec to 10 minutes and draft and insect immune. Model: OD850-F1 Shop CTC Communications for best deals on Bosch Security products & accessories. Bosch Outdoor PIR Tritech detectors are specially designed to take advantage of the physical difference between people and animals and can distinguish between small and large, these factors combined that allow TriTech detectors to tell the difference. They use a combination of passive- infrared (PIR) and microwave detection with advanced signal processing. Motion Analyzer II PIR signal processing Linear travel distance (LTD) microwave signal processing 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). AND/OR Mode This DIP-switch setting specifies whether the detector reports alarm situations in the AND mode (when both technologies simultaneously sense an alarm condition) or in the OR mode (when either the PIR or microwave technology senses an alarm state). OR mode provides faster detection in some conditions as the detector activates the alarm relay based on a single technology input. LEDs The high-efficiency LEDs (one red and one green) use the same technology as traffic lights to make them visible in sunlight. A DIP-switch setting allows the user to disable these LEDs during standard operation to save power. Draft and Insect Immunity The sealed optical chamber prevents drafts and insects from affecting the detector.
