Cannot the SIS and DCS junction boxes be shared?

2026-01-09View Original

Thread Content

I would like to ask whether the SIS and DCS junction boxes cannot be shared? Or can we share one junction box, as long as the cables are not shared? Which standard has relevant requirements?

DCS and SIS systems must be installed separately; if they share the same junction box, it does not count as separate installation

GB/T 50770-2013 5.0.8/5.0.9 The SIS is independent of the DCS; the safety circuits and control circuits are physically separated from each other
