JQB-G Series Gas Alarm Controller Product Features:
①. The controller is embedded with an STM32 low-power, high-performance 32-bit microprocessor, offering advantages such as fast response speed and high stability.

②. Equipped with a maintenance-free lead-acid battery, it easily achieves switching between main power and backup power. When the main power is online, it charges the backup battery. Indicators are provided for main/backup power switching, backup charging faults, and low battery alerts.

③. Features a meter-digit digital tube with rich display content: one row shows real-time alarm channels and alarm types, while another row displays detector concentration in large, clear digits.

④. Ten large buttons enable all functional operations, offering good tactile feedback and Chinese labeling.

⑤. When entering menu settings, corresponding menu items are indicated by indicator lights and labeled in Chinese.
⑥. Monitors detector concentration in real time, triggers different sound and light alarms for probe faults and alerts, and controls six groups of customizable relay outputs.

⑦. The controller allows online setting of low and high alarm values for probes. The high alarm value is fixed at 50% LEL (non-adjustable), while the low alarm range is 1%–25% LEL (default 25% LEL).

⑧. Internal wiring terminals and button switches are accompanied by corresponding Chinese labels. The internal interface board is equipped with a protective cover to prevent contact and short circuits, enhancing system reliability and safety.

⑨. Simple and reliable installation, with wall-mounted design for easy disassembly.
