Working principle

Invisible IR signal beams between transmitter and reciever over a protected distance

Transmitter Reciever

5 / 38Detection Business Unit - GE Security EMEA

Working principle

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

Visibilty diagramGeneal 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

If the average visibility during the normal fog is 80m, it is

recommended not to install a 100 or 200m product.

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.
