A fire smoke damper is an essential component of any fire safety system. It is a device that is designed to close off a duct or other air passage in the event of a fire. The purpose of a fire smoke damper is to prevent the spread of smoke and heat from one area to another, thus helping to contain the fire and limit its damage. Fire smoke dampers are typically installed in walls, ceilings, and floors and are designed to close automatically when the temperature reaches a certain level. They are also used in ventilation systems to help regulate air flow and keep smoke from entering areas where it could be hazardous. Fire smoke dampers are an important part of any fire safety system and can help to protect people and property from the dangers of smoke and fire.
