Fire dampers provide a method of protecting such penetrations and openings. The building codes specify where fire dampers are required, Therefore, until their rated temperature has been met, they can hold the load [damper] open. in. Dynamic closure velocity ratings begin at a minimum rating of 2000 feet per minute (fpm) with optional higher ratings in increments of 1000 fpm above that. are the same. For more information on fire and smoke dampers as well as other opening protectives, you can check also out our various training offerings here. A. What about horizontal assemblies?

Yes it is a good idea to get a different prospective. They are needed in all air transfer openings (non-ducted) in rated walls, regardless of the rating. A: According to NFPA 90A (1999 edition), one-hour fire-rated barriers do not require fire dampers in fully ducted HVAC systems, unless the one-hour fire-rated barrier is a vertical shaft. The operational test may be requiredbe conducted under normal HVAC airflow andnon-airflow conditions. Those that are intended to close under airflow are labeled for use inDynamic Systems(Adynamic systems is an HVAC system designed to maintain the movement of air within the system at the indication of a fire); those that are intended to close after airflow has stopped by automatically shutting down the fan or airflow in the event of a fire are labeled for use in Static Systems(a staticsystem is an HVAC system designed to stop the movement of air within the system at the indication of a fire). Not sure on IBC. For dynamic dampers, the velocity in the duct is within the velocity rating of the damper. Ducts and air transfer openings in fire-resistance rated exterior walls required to have protected openings in accordance with Section 704.14 shall be protected with listed fire dampers in accordance with their listing. If the air duct is an air transfer opening (meaning it is not fully ducted) at the fire-rated barrier, then the duct needs a fire damper where other openings are required to be protected as well. The below graphic provides an example of how this can be interpreted. The higher rating option is for dampers testing at a higher performance level. Smoke dampers are also required in air transfer openings (non-ducted) in smoke partitions. In order for the dampers to be periodically tested and maintained, adequate access should be provided that is large enough to facilitate this. This cookie is set by GDPR Cookie Consent plugin. This is great but there is one miss that I found - the case where a smoke damper is required for penetrations of smoke partitions - the code only requires dampers on transfer openings not on ducts. Both fire and smoke dampers areimportantbuilding and life safetyequipment that protect people and buildings from the effects of fire. * Indicates required field. Fire dampers are products used in heating, ventilation and air conditioning ducts to prevent the spread of fire inside the ductwork through fire-resistant walls and floors. Where a duct passes through a fire hazard room, but does not serve it, fire dampers are not required but the duct must have fire resistance of 30 minutes in respect to integrity and insulation.
