What are the wiring standards for connecting gas detectors to the control system?

Use shielded twisted-pair cables (e.g., RVVP) to prevent signal interference, and ensure the cable cross-section meets the voltage drop requirements (typically ≥1.0mm²). The wiring must be routed through metal conduits or cable trays, and strictly follow the terminal diagram for 4-20mA or RS485 connections to avoid polarity reversal.
