Firestat’s Air Duct Temperature Controllers are designed to automatically close air ducts when temperatures reach a pre-set level. Ideal for use in homes, apartment complexes, and businesses, these switches help prevent fire from spreading by shutting down furnace and fan systems. Our manual switches require human interaction to reset, ensuring the system stays off until it is safe to resume operation.

Our Air Duct Temperature Controllers meet requirements for fire dampers, including those outlined in North Carolina’s Mechanical Building Code 607.3.1.
