The B.E.G. LUXOMAT? VBox and VLBox modules are innovative solutions for low-cost installation of B.E.G. presence detectors in suspended ceilings. They are all part of B.E.G.'s response to the trend in building services technology for supplying reliable components pre-assembled in the factory to cut costs and speed up installation. The current range of presence detectors is also available as a pre-wired range, tailored to specific needs. Functional safety is guaranteed by module function tests in the factory. Thanks to the modular concept, changes can be easily made both during installation and later when modifying use. It is also possible for individuals without specialist training to install the prewired system as colour-coded connectors are used to prevent the poles from being reversed. Specialists are only required to check the complete installation.
