Tool-free wall mounting, flexible cable entry, and optional digital interfaces make it easy to install and maintain in factories, laboratories, HVAC areas, and confined spaces.

FAQ's of Single / Multi Gas Alarm System GD-200:

Q: How does the GD-200 gas alarm system detect multiple gases simultaneously?

A: The GD-200 system utilizes advanced semiconductor and electrochemical sensors to monitor various gases such as LPG, methane, hydrogen, ammonia, and carbon monoxide at the same time. Depending on the selected model, you can detect one or more of these gases simultaneously, providing comprehensive safety coverage for diverse industrial or laboratory settings.

Q: What are the benefits of using adjustable alarm set points for each gas?

A: Adjustable alarm thresholds allow users to set specific concentration limits for each gas, optimizing protection based on the application's safety standards. This customization enhances early warning capability while reducing false alarms, making GD-200 suitable for varying operational requirements and regulatory guidelines.

Q: Where can I install the GD-200 gas alarm system?

A: The GD-200 is designed for wall mounting and is suitable for use in industrial plants, laboratories, confined spaces, HVAC systems, and factories. Its rugged IP-54 rated, flame-retardant ABS enclosure ensures reliable performance even in harsh or variable environmental conditions.

Q: What is the typical sensor life and how often should maintenance be performed?

A: Sensor lifespan ranges from 2 to 5 years, depending on the specific gas monitored and environmental factors. Regular calibration and maintenance are recommended, ideally annually or as indicated by local safety guidelines, to sustain optimal performance and detection accuracy.

Q: How quickly does the GD-200 respond to gas leaks?

A: The GD-200 is engineered for rapid response, triggering alarms in less than 30 seconds upon detecting gas concentrations above the set threshold. This swift action minimizes risk and helps ensure timely evacuation or intervention during hazardous situations.

Q: What process is involved in connecting the GD-200 to external systems?

A: GD-200 features relay outputs, a 4-20 mA analog signal, and optional RS-485 Modbus digital interface, which allow seamless integration with external control panels, alarm systems, or monitoring networks. The terminal block and PG7/PG13.5 cable glands facilitate straightforward wired connections during installation.
