12 m / 40 ft Dual Technology Motion sensor, 9 Curtains, grade 2
Motion sensors of the DD1000 Series incorporate a UTC 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 5.8GHz frequency and will not interfere with any WIFI networks.
