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. Built-in maintenance-free lead-acid battery enables easy switching between main power and backup power. When main power is online, it charges the backup battery. Both power switching and backup charging faults are indicated by indicator lights, with low battery alerts.

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

④. Features 10 large buttons for all functional operations, providing good tactile feedback and labeled in Chinese.

⑤. When entering menu settings, corresponding menu items are indicated by indicator lights and labeled in Chinese.
⑥. Monitors detector concentration in real time, emits different sound and light alarms for probe faults and alarms, and controls 6 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 (cannot be changed), while the low alarm value ranges from 1% to 25% LEL, with a default of 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 touch and short circuits, enhancing system reliability and safety.
