The Sanjiang J-SAP-M-961 fire hydrant button manual provides installation, operation, maintenance, and troubleshooting instructions.
The J-SAP-M-961 fire hydrant button is an electronic fire‑alarm device installed in fire hydrant boxes. When a fire is confirmed, pressing the button starts the fire pump and sends a signal to the fire alarm controller. It features a fully electronic address that can be programmed on‑site, a simple upper‑lower cover design, and a reusable press‑plate that can be reset with a special tool.
The manual covers product overview, technical specifications, wiring diagrams, installation steps, normal operation, reset procedures, regular maintenance, and fault analysis. It also includes safety notes, wiring requirements, and compliance with GB50116‑98 and GB50166‑2007 fire‑alarm system standards. This manual is written in Chinese.
