ABSTRACT:
A novel operator is disclosed for use in combination with a butterfly fire and volume control damper, which operator may be concealed behind a standard concentric diffuser. Only a screwdriver aperture need be provided in the diffuser to facilitate volume adjustment or resetting of the bufferfly damper. In response to excessive heat in the vicinity of the damper, or alternatively, in response to a remote signal received by the operator, the blades of the damper will move to their fully closed position. Once activation conditions have passed, a screwdriver is used to reset the damper to resume its volume control function.
