Why the climate matters

Summer temperatures in Kuwait routinely go above 40°C. Dust and sand are common, and humidity can swing sharply between air-conditioned and external spaces. ELV equipment is often specified from catalogue data that assumes moderate conditions. Checking that data against Kuwait's conditions early avoids premature failures, nuisance faults and short battery life.

Equipment selection

  • Operating range. Compare the operating temperature range of switches, recorders, controllers, UPS and access panels with the maximum room temperature, including the heat the equipment itself adds.
  • Batteries. Battery life falls quickly at high temperature. Specify battery temperature limits, and locate batteries in ventilated, air-conditioned space where possible.
  • Certification and warranty. Ask suppliers to confirm the rated environmental conditions in writing for the specified model, not only for the product family.

Outdoor cameras and field devices

  • Specify housings with an appropriate ingress-protection rating for dust and water, and check the rating against the mounting position.
  • Add sunshields or position cameras to limit direct sun on the lens and housing, which also improves image quality.
  • Use UV-stable cable jackets and approved outdoor cable for external runs, and protect cable entries against dust and insects.
  • Plan access for cleaning lenses and checking housings, especially for cameras on high poles or façades.

Comms rooms and heat load

ELV and ICT equipment adds heat to the room. Include the heat load from racks, controllers, recorders, network switches and UPS in the cooling calculation for each comms room, not only the server space. Where a room has no dedicated cooling, check that the design gives enough air movement, and that alarms or sensors warn of high temperature before equipment is damaged.

Dust, humidity and power

  • Dust control. Use filtered ventilation where it is needed, seal cable entries, and avoid open floor boxes in dusty areas.
  • Humidity. Watch for condensation when air conditioning cycles, particularly on cabinets that move between cool and warm spaces.
  • Power quality. Include surge protection, earthing and bonding, and UPS sizing for ELV loads in the design basis.
  • Cable routing. Where possible, avoid routing cable through hot roof spaces, and check the containment and cable ratings for those routes.

Design checklist

  • Record the design ambient temperatures for each room and external zone in the design basis.
  • Check the operating range of every powered ELV device against those temperatures.
  • Specify ingress-protected enclosures and sunshields for outdoor devices.
  • Add ELV heat loads to the comms room cooling calculation.
  • Include battery temperature limits and locations in the specification.
  • Plan maintenance access for cleaning, filter changes and battery replacement.

Specific values depend on the equipment and the project. Confirm them with the manufacturers and the MEP engineer.
