Main features are as follows.

1)Quad beams detection.
   Four (4) synchronized pulsed infrared beams ensure ultimate stability in any   applications.
They eliminate false alarms by small animals, falling leaves, insects and other small objects

2)Double modulated beams

Double modulated beams eliminate influence of External Light and Electro Magnetic Interference

3)EDC (Environmental Discrimination Circuit)

When the beam reception level is severely dropped in heavy fog, snow or rain, they often cause unwanted alarm activations.
In case of such conditions, environmental trouble signal is output to distinguish from intrusion. EDC gives additional stability in harsh environment.

4)100 times sensitivity allowance

Stable operation is maintained even if 99% of beam energy is lost by fog, snow, frost, insect and etc.

5)Easy optical alignment

Three alignment methods are available and they achieve easy and quick installation.
Scope, LED, Volt meter

6)High IP rate

IP66 is achieved and protect insode of housing from rain, snow, dust, ect.

7) No blocking sheet

When upper or lower beams are aligned, it is not necessary to cover other beams by the blocking sheet.

8)More features for stable operation.
