The Role of Smoke Dampers

February 25, 2020 7:53 am Published by

Fire barriers of a building are designed to prevent the spread of fire and to keep the occupants safe. Fire and smoke dampers are a part of this fire protection system. Dampers are often hidden out of sight, which suggests they’re more likely to be out of compliance.

Smoke dampers are used in the prevention of smoke through the building’s ventilation system. Like fire, smoke can also spread quickly through a building.  Smoke inhalation is a leading cause of death during a fire accident. Prevention of smoke inhalation is very vital to keep the occupants safe during evacuation.

Smoke dampers are specifically designed and installed within the ductwork system and the air transfer openings in the duct system will stop the passage of smoke between sections. Smoke dampers will work by closing off once the smoke is detected by a smoke detector. They are also usually located within the ductwork system. The smoke detectors are usually wired to a central alarm panel where an alarm will send a sign to an actuator attached to the smoke damper. The actuator is located either internally or externally to the smoke damper and can be operated both electrically and pneumatically. The smoke and fire damper blades will be opened and shut off by the actuator using a jack shaft.

The inspection of smoke dampers is as important as fire dampers. It only takes minutes for thick black smoke to fill a hallway or a stairwell. It is important to ensure that your damper system is ready to withstand fire incidents that occur, if any.
