DT906 Dual Tech Motion

The DT906 Dual Tech Motion uses two technologies, microwave and PIR, and features like anti-masking, vandal-resistant housing, large coverage patterns and three micro controller-based sensitivity modes, make the powerful DT900 DUAL TEC & sensors ideal for the harshest commercial and industrial environments.Micro controller-based Dual Technology Microwave and passive infrared (PIR) technologies, combined with micro controller-based advanced signal processing, provide excellent detection while virtually eliminating false alarms and costly service calls. The DT900 Series uses Active Infrared for anti-masking to detect attempts to mask the sensor. The patented look-down lens catches saboteurs who try to disable the unit from below, while three different tamper switches deter would-be criminals from physically damaging the sensor. The patented INFORMER® function, designed primarily as a diagnostic tool, monitors for sensor blockage and can help identify a sabotage situation.Queue Logic Event Processing The micro controller in the DT900 converts all incoming microwave and PIR signals from analog-to-digital format. If the signal is determined to be valid it enters the Queue Logic Event Process. This process stores the valid signals within a moving window of time, keeping up to eight events for each signal type. Based on the First In First Out (FIFO) concept, Queue Logic requires a sophisticated on-board micro controller to make advanced calculations for qualifying a sequence of events as an actual alarm.Self-Test and Continuous Supervision for High Reliability This industrial-grade sensor performs multiple levels of supervision. The INFORMER function checks each technology continuously. The micro controller conducts a self-test of the sensor's functions at regular intervals, and reports any trouble using the on-board trouble relay.Designed for Harsh Environments Vandal resistant housing combined with a zero clearance bug guard make the DT900 series ideal for commercial and industrial applications such as warehouses, large retail facilities, manufacturing sites and schools.Self-Adjusting Thresholds The on-board micro controller automatically adjusts the microwave and PIR thresholds to compensate for environmental disturbances not related to actual intrusion events. True temperature compensation continually optimizes the performance of the PIR to account for changes in room temperature. Environmental noise compensation keeps common environmental disturbances such as fluorescent lights from causing the microwave to false alarm.Technology- PIR for intrusion detection- Microwave for intrusion detection- Active infrared for anti-masking (DT900 and DT906)Digital Digital filter virtually eliminates interference caused by fluorescent lighting.Three Micro controller-based Sensitivity Modes Sensor sensitivity can be set to high for fastest capture, to normal, or to low for maximum false alarm immunity in harsh environments. Sensitivity 2-4 steps within field-of-view, depending on sensitivity setting selected.Zero Clearance Bug Guard. The bug guard provides zero clearance, protecting the pyro chamber from insects that can cause false alarms. Immune to small animals commonly found in commercial conditions (birds, rodents, snakes). Designed with the installer in mind, the DT900 contains a large wiring space, protective clear plastic covers over the circuit boards to prevent damage, two end-of-line terminals, flashed over LED's visible at great distance, a fast-install wall mounting plate for the included swivel mounting bracket, and easy vertical and horizontal adjustment.Mirror Optics For Long Range. The DT900 series utilizes custom designed mirror optics to provide effective capture at long range. Each model is easily selectable between two ranges. The LED's will display codes to indicate an anti-masking condition, INFORMER condition, trouble condition, and re-callable codes to indicate INFORMER results and whether or not there was a self-test failure.Advanced Commercial/Industrial Features. In addition to anti-masking (DT900/DT906), the DT900 Series has command input for initiating a self-test remotely, has CENELEC two wire input options, and has a remote LED enable input.PIR Fields-of-View (Edges)61 m (200') Range 27 m (90') Range Long: 2Long: 18Intermediate long: 6Intermediate long: 18Intermediate: 4Intermediate: 16Intermediate lower: 4Intermediate lower: 12Lower: 8Lower: 8Look-down: 2Look-down: 237 m (120') Range 15 m (50') Range Long: 6Long: 18Intermediate long: 4Intermediate long: 16Intermediate: 4Intermediate: 12Lower: 8Lower: 8Look-down: 2Look-down; Download Brochure
