Honeywell DT906-61 Dual-Tec Series detectors incorporate PIR and microwave detection technology, have pet tolerance, low consumption of 50mA, temperature compensation, anti-masking, are 134 x 178 x 210mm in size, and can operate in a temperature range of -10 to 49C.
According to Honeywell, microwave and passive infrared (PIR) technologies, combined with microcontroller-based advanced signal processing, provide excellent detection while virtually eliminating false alarms and costly service calls.
The DT900 Series uses Honeywell Active Infrared for anti-masking to detect attempts to mask the sensor. The patented look-down lens catches intruders who attempt to disable the unit from below, while 3 different tamper switches deter would-be criminals from physically damaging the sensor. Meanwhile, the patented INFORMER function, designed primarily as a diagnostic tool, monitors for sensor blockage and can help identify a sabotage situation.
The microcontroller in the DT900 converts all incoming microwave and PIR signals from analogue-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 8 events for each signal type. Based on the First In First Out (FIFO) concept, Queue Logic requires a sophisticated on-board microcontroller to make advanced calculations for qualifying a sequence of events as an actual alarm.
Supervision for High Reliability This industrial-grade sensor performs multiple levels of supervision. The INFORMER function checks each technology continuously. The microcontroller conducts a self-test of the sensor’s functions at regular intervals, and reports any trouble using the on-board trouble relay.
Vandal resistant housing combined with a zero-clearance bug guard make the DT-900 series ideal for commercial and industrial applications such as warehouses, large retail facilities, manufacturing sites and schools.
The on-board microcontroller 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.

Hi do you have any of the DT609
Hi, Darron – if you’re in Australia, CCTV Masters based at Bankstown in Sydney distributes Honeywell sensors and currently has the DT901 long range dual tech on sale for about 30 per cent off. They may be able to advise or source the DT906 Let us know if you have no luck and we’ll ask the market. JA
