June 3, 2021  CCE

Belimo damper actuators and most of the valve actuators and sensors meet UL 2043 requirements.

The National Electrical Code Section 300.22 (c) requires electrical devices in plenums to be tested to UL 2043 for low smoke generation. Underwriters Laboratories’ UL 2043 is the standard for fire test for heat and visible smoke release for discrete products installed in air-handling spaces.

Belimo products used for installation in air-handling spaces meet UL 2043 standard for heat and smoke release. By complying with the UL 2043 requirements, our products have demonstrated the following characteristics:

  • A peak rate of heat release of 100 kW or less
  • A peak normalized optical density of 0.50 or less
  • An average normalized optical density of 0.15 or less

The Belimo products that comply with UL 2043 have the certification mark of UL on the product.

Belimo products are certified according to UL 2043 and are listed on the Online Certifications Directory at www.ul.com/database.
