Beam Fence
- Technology : Infrared beams
- Range : 30 m.
- Alarm OUT: Contact relay
- Applications: Governmental, Industrial, Residential
Midi patented bi-directional infrared beam barriers for the protection of industrial buildings, long balconies and corridors.
It is made up of two microprocessor logic circuits mounted with the SMD technique which manages up to 8 pairs of optical circuits within up to 3 meters aluminium pillars.
Optics are multiplexed, and the alarm sounds when two optics are obscured (AND function).
Maximum outdoor range 30 meters.
OPERATION
Transmitters and Receivers are crossover mounted on both pillars, allowing at least one beam to work when the other is obscured by sunlight. The installation of Beam Fence is very simple due to the automatic detection and setup of the beams, you can add additional beams to the system (BSN050HS) and the microprocessor logic automatically recognize them with no need of any setup procedure.
