Abstract
PURPOSE: To prevent a person existing on the scence of a fire from suffering from oxygen starvation with fresh air fed in and to enable operating of a damper even in the case of the failure in current, by a method wherein a smoke-eliminating damper is opened and an air-feed damper is also opened by detecting smoke.
CONSTITUTION: With a fire-sensitive unit 12 detecting fire smoke, a smoke-eliminating damper 4 is first opened, and the damper 4 so opened is detected by means of a limit valve 5. An air-operated control circuit unit 11 actuates a smoke-eliminating rotary cylinder 3 in conjunction with an air feeding rotary cylinder 7, and as a result, an air feed damper 8 is opened. Where the smoke-eliminating damper 4 is not opened due to some reason, the air feed damper 8 does not open, whereby smoke is agitated with air fed from an air duct 10 and thus the whole of a room 2 is not filled with smoke. This minimizes the possibility of danger, and an air-operated device permits opening of the dampers 4 and 8 even in the case of the failure in current.
