2. Antimasking
The antimasking function in COBALT detectors is based on detection of objects, which reflect
microwaves and move close in front of the detector (up to 10 – 20 centimeters), thus
preventing any attempts to cover it. For the protection against consequences of covering
detector with the material which does not reflect the microwaves, but isolate from IR
radiation, it is necessary to choose the detector microwave counting mode (take off the JP3
jumper).
3. Lenses
In the detector is mounted an extra wide angle lens, however, it is possible to replace it by
buying another lens with different characteristics (range, number of beams, angle of view).
Lenses are available with the following characteristics:
№ Lens type
1 extra wide angle (EWA)
long range with access zone
2
monitoring (LR)
3 vertical barrier
NOTE: The detector operating range should be selected to match the size of space where
the detector will be installed. The size of the space along the main direction of
detector positioning is not to be less than 1/3 the nominal range of the detector.
Improper selection of the lens may cause excessive sensitivity and trigger false
alarms.
