Why GDS Systems Are Not Allowed to Use Bus Architecture (Including RS-485 Networks)
Gas Detection Systems (GDS) are categorized as critical safety systems. Their primary functions—real-time gas concentration monitoring, alarm triggering, and emergency interlock—require extremely high reliability, fast response, and fail-safe communication. For this reason, international and domestic standards clearly state that GDS field detectors must NOT be connected using a shared bus network, including RS-485 multi-drop wiring.A […]
