Aritech DD105 is a dual technology PIR and microwave sensor with a detection range of 12 metres and a detection angle of 86 degrees distributed by Hills.

The sensor features 7 curtains, has current consumption in alarm of 15.0 mA and a mounting height of 1.8 to 3.0 metres. The housing meets IP30 – IK02 when installed with a sealed cable entry, there’s a normally closed relay and a dual loop end-of-line feature. Power supply is 9-15V DC, dimensions are 123 x 61 x 58mm, operating temperature is -10 to 55C.

Other features include Gliding Focus Mirrors, high quality microwave technology, and the latest 4D signal processing. Twin Opposed Antennae ensure a better signal to noise ratio and better microwave direction. The DD 100 series also features solid curtains of detection. Full undercrawl protection gives maximum security while the special characteristics of the ‘gliding curtain’ ensure not only better intruder detection but also better PIR stability from the environment.

There’s also Distance of Motion (DoM) Processing. This proprietary microwave processing converts the analogue signal into a digital one where the custom ASIC can effectively measure the distance travelled by the intruder, irrespective of the intruders speed or distance from the detector. This gives a significantly more uniform microwave signal over the entire protected area.

These sensors are able to adjust both PIR and Microwave channels. 4D processing allows the PIR channel to intelligently analyse a signal pattern and distinguish between real human movement and false alarm hazards. The PIR channel is resistant to false alarms by analysing the size, shape and speed of successive signals.
