Gas detector Gazex DEX-12/N two-channel dual-gas detector, wall mounting

Gazex DEX-12/N two-channel dual-gas detector is a wall-mounted unit engineered for continuous monitoring of two different gases in industrial and commercial environments. The device contains two independent sensing channels that operate simultaneously, providing separate detection and alerting for each monitored gas. Designed for fixed installation, the detector supports applications where compact, reliable and continuous gas surveillance is required to maintain safety and operational continuity.

Advantages

The detector offers independent dual-channel measurement, allowing simultaneous monitoring of two gases without cross-interference. Wall mounting simplifies installation in confined or dedicated utility spaces while keeping sensors accessible for maintenance. The unit provides continuous real-time detection and configurable alarm outputs for integration with building management or safety systems. Robust construction and reliable sensing electronics are suitable for long-term use in boiler rooms, mechanical rooms and industrial zones.

Suitable for

• Boiler rooms and heating plants
• Mechanical and utility rooms
• Industrial production areas with two-gas monitoring needs
• Commercial facilities requiring fixed gas surveillance

Key specifications

• Two independent sensing channels for simultaneous gas detection
• Wall-mount design for fixed installation
• Continuous real-time monitoring capability
• Configurable alarm outputs for system integration
• Suitable for combustible and/or toxic gas sensing depending on sensor selection

How to use

Mount the Gazex DEX-12/N on a stable wall surface at the height and location recommended for the gases to be monitored. Connect power and alarm output wiring according to installation instructions and integrate outputs with local control or alarm systems as required. Configure channel-specific alarm thresholds and sensor types to match the gases present in the environment. Perform an initial calibration or sensor verification following manufacturer guidelines before commissioning to ensure accurate readings.

Usage recommendations

For reliable performance, place the detector where air circulation represents typical gas distribution for the monitored area and avoid mounting near strong drafts or direct heat sources. Schedule periodic inspection, calibration and sensor replacement according to operating environment and manufacturer intervals. Ensure alarm outputs are connected to appropriate notification or shutdown systems and verify system response during commissioning and routine tests.
