Active Infra-Red Beam Sensor – Perimeter IR Beams

The Perimbar perimeter barriers comprise an array of modulated and synchronized infra-red beams fitted in slim columns available in heights of 1.0m, 1.5m, 2.0m, 2.5m, 3.0m, 3.5m and 4.0m. Perimbars are constructed from heavy-duty aluminium extrusions with special filter material windows on three sides concealing the beam positions, directions and patterns. The columns have universal fixing points allowing mounting on walls and posts. The columns may be installed up to 100m apart. By linking these 100m sections, many kilometers of perimeter can be protected.

The infra-red transmitters and receivers cinstalled in the columns have a range of 100m, with 90% attenuation (test filters supplied). In addition to the transmitter and receiver modules, other units such as heaters, thermostats, system performance monitors and low voltage power units can be fitted.

A synchronizing link (Synclink) facility is included on each transmitter and receiver to provide greater security and easy multi-beam operation. Utilizing the Synclink avoids the need to transpose sets of transmitters and receivers in multi-beam arrangements and also allows larger numbers of beams with close groupings in single columns for operation over adjacent vertical beam paths. Synclink also avoids spurious beam interaction where barrier housings are not in line and in ‘dog leg’ situations.
