IR81A
Achieved ZERO false alarm under different environment by following unique
methods.
1) Separating the function of two mirrors for long range and other two mirrors for short range.
2) Dividing each detection zone into two, one is for higher position and other is for lower position.
The small animal is not detected at these higher and lower position zone simultaneously.
3) Shifting the two higher and lower position zone horizontally.
Above three technologies complement each other and eliminate any alarms by small animals and other objects.
Detection direction and distance are adjustable.
Detection range can be extend up to 15m.
Horizontal range : 15m, 90 degree,
Height: 2.3m – 4m
Restrictions on the installation are reduced, and it becomes inconspicuous.
Diameter : 125mm
Eliminate a gap of the cover and body thoroughly and does not allow the invasion of insects and wind which is a factor of false alarms.
The body can be removed from the base easily so that the installation and adjustment is easy.
It is possible to fix the release button by the lock screw so that not to be able to remove the body without the use of a tool.
High reliable application for the indoor ceiling mount.
