Dynacon – Authorized Firestat Distributor

Dynacon, a HVAC distributor based in Virginia, acts as a crucial intermediary between manufacturers like us and contractors. They assist contractors by providing guidance and expertise to ensure compliance with building codes. This includes helping select products like our Firestat switches that meet regulatory standards, particularly in areas of fire safety and HVAC system requirements.

Our Firestat switches are key to enhancing safety standards within high-density residential structures, particularly in regions like North Carolina. Endorsed for implementation in such settings, these switches are engineered to automatically deactivate fans in the event of a fire. This critical function effectively prevents the spread of smoke through the ductwork, thereby minimizing potential hazards. Such proactive measures align seamlessly with the stringent requirements of the Mechanical Building Code in states like North Carolina.

Understanding the critical function of our switches in building safety prompts a closer examination of the building codes mentioned. Acting as a regulatory framework, building codes establish minimum standards for the construction and operation of buildings and structures. These codes are important for ensuring public safety and welfare and gain legal validity upon adoption by regulatory authorities. Many local regulations mandate the installation of sensing mechanisms to deactivate airflow within ducts upon detecting a significant temperature increase. This requirement is particularly pertinent for multi-family dwellings with shared HVAC systems, aiming to contain smoke and prevent its spread.

CEMCO Duct Limit Switches

The Firestat Duct Fan and Limit Thermostat Switches operate using the same physics to ensure HVAC safety. A helix bi-metal element senses a rapid temperature change. When the temperature changes the bi-metal expands and triggers a snap action switch and either opens or closes a circuit. These switches are commonly installed in air ducts designed to shut down heating, air conditioning and ventilation equipment in apartment complexes and other multiple dwelling units when air temperature exceeds the set point.
