How to Properly Install Gas Detectors in Locations Without Supporting Structures？

—— Standardized Installation Method for Fixed Gas Detectors in Open Spaces

✅ 1. Recommended Installation Methods

1. Mounting on a Stand or Pole

• Freestanding Pole: Use stainless steel or galvanized steel poles as a support structure to securely mount the detector.
• Base Fixing Options:
  • Use embedded anchors with concrete to ensure stability;
  • If ground modification is not allowed, use a heavy-duty weighted base as a temporary alternative.
• Installation Height:
  • Chlorine is heavier than air, so the detector should be mounted 0.3–0.6 meters (1–2 feet) above the ground, near potential leakage points.

2. Power Supply and Wiring

• Use corrosion-resistant and explosion-proof cable conduits or trays;
• Install a junction box on the pole, preferably on the side or back to protect it from weather and mechanical damage;
• Ensure cables are properly fixed to prevent sagging, disconnection, or tripping hazards.

✅ 2. Key Installation Considerations

1. Detector Placement

• Position the detector close to potential gas leak sources;
• Avoid placing near direct wind, rain exposure, or direct sunlight;
• Ensure the detector is in a well-ventilated area without obstructions that could block gas diffusion.

2. Space for Maintenance

• Leave enough clearance for inspection and maintenance;
• The front of the detector should be unobstructed for easy visibility of indicators and safe manual testing.

3. Environmental Resistance

• For harsh or corrosive environments (e.g., chemical plants, water treatment facilities, disinfection rooms), ensure the detector meets:
  • Corrosion-resistant housing (such as 316 stainless steel);
  • Explosion-proof certification (e.g., Ex d or Ex ia);
  • IP65 or higher protection rating against dust and water.
