Honeywell – DT901 DUAL TEC® DT901 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® DT901 commercial motion detectors ideal for the harshest commercial and industrial environments. DUAL TEC DT901 commercial motion detectors are a high-grade motion sensor specifically designed for indoor commercial use. The robust and reliable device can detect movement from up to 90 ft away. Its advanced dual detection technology helps prevent false alarms. A dual-tech motion helps prevent false alarms. This is because the device will only alert the system if both its PIR sensor and its microwave sensor are activated. The advantage to this is that the sensor will respond accurately to true motion events, while ignoring potential false alarms. A user might prefer to use a DUAL TEC motion sensor over a standard PIR-only motion sensor if they are experiencing false alarms due to environmental factors like airflow or heavy sunlight. The user will also appreciate the three microcontroller-based sensitivity modes of the DUAL TEC DT901 commercial motion detector that helps allow the device to better meet their unique needs. A walk test should be performed after configuring. 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 onboard 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
