Scudo BUS

Combivox triple technology detector (2IR + MW), with connection to RS 485 BUS. Curtain detector fully designed by Combivox R&D team. Ideal for outdoor perimeter protection of windows, dormers, skylights and wall facades where more openings appear, thanks to the coverage that guarantees up to 12 meters if installed at a height of 2,4 m.

Coverage angle 13°.

The detector is equipped with MEMS accelerometer against any attempt of burglary or detachment from its housing ensuring maximum reliability and easy installing, eliminating the classical problems of electromechanical systems related to the imperfections of the surfaces and weather conditions.

Possibility to bypass the MW, totally or in case of disarmed system.

Configuration, through Programming software, of IR-sensitivity adjustment on four levels through DIP-switch and MW-sensitivity adjustment on ten levels. Through specific adjustments, if installed at a height of 1,2 m, Scudo WT is able to operate also in the presence of small animals (PET IMMUNE).

Sleeping time: about 2 minutes. Equipped with bracket for lateral wall mounting.
