The SB250/SB2100 two-beam detectors and the SB450/SB4100/SB4200 four-beam
detectors generate an alarm when all the beams are broken simultaneously, ignoring
birds, small animals, dead leaves etc.
They consist of a transmitter module and a receiver module, which are installed facing
each other over the distance to be protected, providing a non-physical invisible detection
zone.
The detector is based on a system of pulsed infrared beams, and operates on four user-
selectable frequencies (channels), avoiding any risk of interference between detectors or
from external light sources such as the sun, street lighting, other infrared sources etc.

Principal features
• Maximum outdoor range:
SB250: 50 m
SB450: 50 m
The range of an infrared detector depends directly on visual range.
Maximum range of an infrared cell varies according to visibility. For example:
- When visibility is 200 m, the range is 200 m.
- When visibility is 60 m (dense fog), the range is 60 m.
• A fog detector cuts the intruder alarm when there is a drop in the infrared signal due to
fog, heavy snow or heavy rain etc.
• Four user-selectable frequencies for distinguishing between different detectors.
• SB250 and SB2100 detectors equipped with two beams (1 twin-beam cell).

SB2100: 100 m
SB4100: 100 m
SB4200: 200 m
