Description

When a fire occurs, fire dampers automatically close, preventing flames and smoke from spreading through the ducts into adjacent fire compartments.
When the temperature rises to 72 C or 95 C (for warm air ventilation systems), the fusible link melts and the fire damper closes. The trigger mechanism is easily accessible and can be checked from the outside. One or two limit switches (optional) are used to indicate the valve position.
