Filed:

Jun 30, 1997

Appl. No.:

8/885892

Inventors:

John Vole - Lincolnshire IL

International Classification:

F24F 7013

US Classification:

454239

Abstract:

A detector in a space to be sensed and controlled gives an electrical signal upon fumes in the space reaching a predetermined level. An electrical circuit is thereby energized to operate a fan to exhaust the space. Inlet and outlet openings in the structure enclosing the space are biased closed but open in response to air pressure on operation of the fan. Also the main door is opened by mechanism actuated by the signal. When the main door is open, the circuitry for opening the main door is open, and there is no actuating the apparatus.
