Abstract (en)
A fire-shutter (12) is rotatable within a duct (10) between an open and a closed position. A shutter-tripping unit supported on a base plate (22), mounted externally on the duct, has a heat sensor (56) projecting within the duct and a spring-loaded mechanism triggered by the heat sensor to move the shutter to a tripped position in case of abnormal heat. The spring-loaded mechanism comprises a spring-driven rotatable shaft (24) extending through said base plate (22) and duct wall (10), a crank (28) keyed to the shaft and a linking rod (30) having one end linked to the crank and its opposite end linked to a bracket (32) carried excentrically on one side of the shutter (12). <IMAGE>
