Solution Design

10–15 m spacing at bar screens, pump rooms, dewatering, and galleries; alarms linked to local ventilation and personnel alerts.

System Architecture

📡

Sensing Layer

Fixed detectors cover Bar screen, Aeration basin, Dewatering room, Digester, Underground gallery and other critical zones; portable instruments for patrol and pre-entry checks.

🎛

Control Layer

SP-1003PLUS wall-mounted gas alarm controller with multi-channel monitoring and relay interlocks to fans, shutoff valves, and audible-visual alarms.

📊

Transmission

4-20mA + RS-485 Modbus redundant upload for unmanned remote sites.

🖥

Application Layer

DCS/SCADA integration, historical trends, alarm statistics, CCTV verification.

Detector Placement

Prioritize leak sources and downwind positions; account for gas density and airflow
Dense coverage in enclosed/semi-enclosed areas (galleries, pump rooms), typically 10–15 m spacing
Graded high and high-high alarms; high-high enters safety interlock logic
