Motion sensors of the DD1000 Series incorporate a Carrier Fire & Security patented and unique range gated radar technology allowing the installer to define a clear borderline of the radar range as the radar is used to measure distance between the sensor and moving objects. Effectively the end-user will get rid of any nuisance alarms generated by movements outside the detection pattern.
Every motion sensor comes with 4 possible radar ranges selectable via dip switches allowing the detection pattern to be tailored according to the room where the motion sensor is installed. The radar operates on 5.8 GHz frequency.
The DD1012-N motion sensor incorporates a new digital pyro for an improved signal quality and a better immunity to electrical interferences.
The patented optical mirror technology gives the advantage of gliding focus, which creates a continuous detection curtain from floor level up to installation height. Within the DD1012 series Aritech are using a dual element pyro generating 2 volumetric curtains for each of the 9 curtain sets.
These dual tech motion sensors generate an alarm depending on what both technologies – range gated radar and PIR – saw within its detection coverage.
But the dual tech go beyond a simple “AND” function : it classifies the signals from each technology – range gated radar and PIR – to have the best alarm result without being sensitive for nuisance signal sources. This technology creates a uniform sensitivity in all course directions.
