MAPRO make Fire Damper is a perfect combination which perform both functions i.e. A) Fire Damper and B) Smoke Damper. Building layouts and designs often combine fire rated partitions with smoke barriers requiring the installation of both a Fire Damper and a Smoke Damper at a same location. All type of Fire Dampers and Combination Fire Smoke Dampers must be qualified under UL Standard 555-1995 (presently prevalent in India and tested by Central Building Research Institute, Roorkee) as a Fire Damper. The consideration mentioned above applies to the selection and application of both Fire and Combination Fire and Smoke Dampers.
Fire Dampers are required by all building codes to maintain the required fire resistance ratings of walls, partitions, and floor when they are penetrated by air ducts or other ventilation openings. One of the basic requirements of building fire protection as required by all building codes is the compartmentation or dividing up of buildings using fire rating walls, floors, or other partitioning methods. This compartmentation concept is intended to contain any fire to the compartment of the fire origin and thereby minimise damage to property and protect the lives of people living and/or working in the building. A duct or ventilation opening in any of the fire rated partitions would permit a fire to spread from the compartment of origin to adjoining compartments or spaces. Fire dampers are installed in these duct or ventilation openings. They close automatically upon detection of heat (usually the melting of a fusible link at 74 degree C) blocking the opening and preventing the spread of fire into the adjoining compartment.
