enum
Value
This enumeration defines the various types of damper:
BALANCINGDAMPER: Damper used for purposes of manually balancing pressure differences. Commonly operated by mechanical adjustment. BACKDRAFTDAMPER: Backdraft damper used to restrict the movement of air in one direction. Commonly operated by mechanical spring. BLASTDAMPER: Blast damper use to prevent protect occupants and equipment against overpressures resultant of an explosion. Commonly operated by mechanical spring. CONTROLDAMPER: Control damper used to modulate the flow of air by adjusting the position of the blades. Commonly operated by an actuator of a building automation system. FIREDAMPER: Fire damper used to prevent the spread of fire for a specified duration. Commonly operated by fusable link that melts above a certain temperature. FIRESMOKEDAMPER: Combination fire and smoke damper used to preven the spread of fire and smoke. Commonly operated by a fusable link and a smoke detector FUMEHOODEXHAUST: Fume hood exhaust damper. Commonly operated by actuator. GRAVITYDAMPER: Gravity damper closes from the force of gravity. Commonly operated by gravitational weight. GRAVITYRELIEFDAMPER: Gravity-relief damper used to allow air to move upon a buildup of enough pressure to overcome the gravitational force exerted upon the damper blades. Commonly operated by gravitational weight. RELIEFDAMPER: Relief damper used to allow air to move upon a buildup of a specified pressure differential. Commonly operated by mechanical spring. SMOKEDAMPER: Smoke damper used to prevent the spread of smoke. Commonly operated by a smoke detector of a building automation system. USERDEFINED: User-defined damper. NOTDEFINED: Undefined damper.
