The synchronized Quad beams based on high technique are designed for eliminate false and miss alarms.
Main features are as follows.

1) Quad beams detection

• Four (4) synchronized pulsed infared beams ensure ultimate stability in any applications.

• They eliminate false alarms by small animals, falling leaves, insects and other small subjects.

2) Stacking units.

• Up to 4 units stacking is allowed.

3) HD AND mode

• When stacking units, upper and lower units can make AND fuature. And it makes higher density protection zone than before.

4) AND / OR mode selection

• AND: When Four (4) beams are blocked simultaneously, Alarm is activated.

• OR: When either of upper 2 beams OR lower 2 beams are blocked, Alarm is activated.

• OR mode protect from the intruder craws through the lowest beams. Maximum 200m outdoor and 400m indoor are available.

5) Double modulated beams

• Double modulated beams eliminate influence of External light and Electro Magnetic Interference

6) 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.

7) 100 times sensitivity allowance

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

8) Easy optical alignment

• Three alignment methods are available and they achieve easy and quick installation.

• Scope, LED, Volt meter

9) High IP rate

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

10) No blocking sheet

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

11) More features for stable operation.

Selection Tips
1) Quad beam detector is more reliable than Dual beam detector.

• It is recommended for Important facility , e.g. Airport, Seaport, Plant, Factory, Millitary base, ect.

2) Long distance application.

3) Stacking application.
