This sensor is equipped with a DUAL ZONE system which initiates an alarm only when detection occurs in both horizontal and downward zones simultaneously. No alarm signal is given if only one zone is activated by small animals, vehicles etc.
Perimeter, window or wall detection can be made by adjusting detection zone with area masking sheet. MS-12FE equipped with two sensors can cover two perimeters or windows by itself.
180 degree coverage detection is possible by using both upper and lower sensors in "OR" detection mode.
Rain-proof structure facilitates outdoor installation. Various mounting position such as wall and pole can be chosen.
Sensitivity can be adjusted between 30% and 170%.
