5WG1258-8AB12 S258 12 Mounting Plate 4-Gang Box for UP 258 White
The 5WG12588AB12 (S 258/12) is a mounting plate that enables installation of UP 258 KNX presence detectors into 4-gang (4*4) junction boxes. The plate bridges the gap between the UP 258's standard 55 mm footprint and the larger 4-gang box format commonly found in commercial electrical infrastructure.
Finished in white (similar to RAL 9016) to maintain a clean, consistent appearance on walls and ceilings. This accessory simplifies integration of UP 258 detectors into existing conduit or trunking installations without altering the ceiling grid or wiring arrangement, making it a preferred solution for new-build commercial projects.

The S 258/12 mounting plate is essential in commercial new-build projects where 4-gang junction boxes are pre-installed in ceiling voids or conduit runs. It eliminates the need for additional back boxes and allows the UP 258 presence detector to be fitted cleanly into the existing electrical infrastructure.
Commonly specified in office fit-outs, hotel room builds, school classrooms, and healthcare facilities. The white finish matches standard ceiling surfaces for a discreet installation. Works in conjunction with the UP 258 KNX detector and DELTA switch covers to form a complete, code-compliant automation node.
