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.

Features & Benefits:

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
