JB-TB-GDB18 Gas Alarm Controller

JB-TB-GDB18 Gas Alarm Controller

Monitor multiple gas-detector points and make their alarms and control signals easier to manage together.

  • Bring mixed detector wiring together

    The listed 4–20 mA, four-bus and two-bus interfaces offer connection choices for the planned field network.

  • Respond to the right point

    Configurable gas names and alarm thresholds, local indication and relay outputs support a site-specific response.

  • Investigate system status

    The controller's signal processing, fault detection and online zero correction support operator review and maintenance.

Overview

The JB-TB-GDB18 gas alarm controller is a multi-point monitoring gas alarm controller developed by our company. It is used to detect the concentration of target gases in the ambient air, capable of integrating multiple detectors for different gas components and simultaneously monitoring multiple points. This product also features both split-wire and bus interfaces, meeting the needs of various wiring configurations for the detectors. This system uses a microprocessor as the control unit and high-precision sensors as detection components, offering high sensitivity and fast response. When the concentration of the target gas detected in the environment reaches or exceeds the warning threshold, the controller immediately triggers an audio-visual alarm to alert us to take timely safety measures. It also activates the control unit to manage the exhaust ventilation or other peripheral devices, preventing poisoning incidents, explosions, and fires, thus ensuring the safety of lives and property. The design, manufacture and verification of this product comply with the following national standards: GB 12358—2024 General technical requirements for environmental gas detection and alarm instrument in workplaces
