DUAL TEC® DT900 Series Commercial Motion Detector

The use of two technologies ” microwave and PIR ” and features like anti-masking, vandal-resistant housing, large coverage patterns, and three microcontroller-based sensitivity modes, make the powerful DUAL TEC® DT900 commercial motion detectors ideal for the harshest commercial and industrial environments. DUAL TEC DT900 commercial motion detectors incorporate safe-guards that prevent tampering from professional intruders. Advanced sabotage prevention uses anti-masking technology to detect when someone is attempting to mask the sensor. The look-down lens is able to see when an intruder is trying to disable the sensor from below. Three tamper switches protect the sensor from criminals looking to damage the sensor.

• Patented INFORMER® function, designed primarily as a diagnostic tool, monitors for sensor blockage and can help identify a sabotage situation
• Microcontroller converts all incoming microwave and PIR signals from analog-to-digital format
• INFORMER function checks each technology continuously while the microcontroller conducts a self-test of the sensor's functions at regular intervals, and reports any trouble using the on-board trouble relay
• 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
• Sensor sensitivity can be set to high for fastest capture, to normal, or to low for maximum false alarm immunity in harsh environments
• Two to four steps within field-of-view, depending on sensitivity setting selected
• Bug guard provides zero clearance, protecting the pyro chamber from insects that can cause false alarms
• Utilizes custom designed mirror optics to provide effective capture at long range
• LEDs will display codes to indicate an anti-masking condition, INFORMER condition, trouble condition, and recallable codes to indicate INFORMER results and whether or not there was a self-test failure
