Working principle Invisible IR signal beams between transmitter and reciever over a protected distance Transmitter Reciever

Working principle 2° Transmitter Reciever Transmitter send a light signal which is invisible to human (infrared signal wave of 900nm). Reciever act as a elctronic eye, analyze the amplitude of the signal send by transmitter

Working principle Not sensitive to rain 2° Transmitter Reciever Not sensitive to rain Not sensitive to any movement doesn’t cut the beams Not sensitive to EM wave and signals

Communication principle Pulsed beams and selectable channels Ch1 Ch2 Ch3 Ch4 Channels are made by pulse frequency Rec Trans Receiver on ch1 will only see the Transmitter on ch1 & … Ch 1 Ch1 Ch 2

Switching principle SB250 / SB2100 Communication princple: Pulsed beams and selectable channels Rotection zone is about 20cm Both beams needs to be intruppted to trigger the alarm

Switching principle SB450 / SB4100 / SB4200 Communication princple: Pulsed beams and selectable channels Rotection zone is about 40cm Both beams needs to be intruppted to trigger the alarm

Visibilty diagram AIR Range Geneal rule: the range is equal to visibilty on site. The SB series range Theoretical max range: 2550m When the visibility is 200m, the range will be 200m When the visibility is 60m (fog), the range will be 60m AIR Range 200m 100m 50m If the average visibility during the normal fog is 80m, it is recommended not to install a 100 or 200m product. 80m 50m 100m 200m Visibility

Fog dectection Receiver analyse the signal power

Fog dectection When the signal amplitude at the reciever reaches the minimun level the disqualification relay will be triggered,

Spec. Feature If the alarm relays are connected in serie and there is a steady obstruction, the AIR beam will release the alarm relay and trigger disqualication relay. Alarm relay (NC) Max 60 s Disq relay (NO)

External perimeter protection Active Infra Red Motion sensors Mounted in Pillars

Mounted in pillars To increase the protection hight, SB beams can be mounted in a mouting pillars. Available in : 1m, 1.5m, 2m, 2.5m, 3m

Back to back moting Both sides of the pillars can be used for the back to back mounting

Beam alignement Horizontal alignment Vertical alignement

Power supply cable selction Cable lengthe for power supply of 12V DC Cable lengthe for the heater of 12V DC/AC In case the mentioned cable lengthe/diameter limits your installation, use the optional 230VAC power supply (SB52)

Installation guideline The protected area should not cut any beams

Installation guideline Max 10° as accepted for the correct functionality Maximum 10°

Installation guidelines Fence is the best physical perimeter protection which keep the large animals away

Installation guidelines No vegeation my be between the Tx and Rx
