Risco's wireless twin beam is based on the unique technologies of Risco's wireless barrier beams including direct sunlight immunity, green consumption technology, and front mounting modules.

The wireless twin beam is compact in size, yet superior to three PIR curtain detectors. A single beam can protect several windows with its enhanced 10m range. With the wireless twin beam, windows can be left open to the breeze and people can move freely about the room, even near the window area, without causing false alarms.

These wireless twin beams also provide high false alarm immunity from falling leaves, small animals and direct sunlight. Additional features include simple beam alignment, anti-sabotage with encrypted ID and anti-collision between adjacent units.
