Abstract

See full text

A firestop device includes a collar to be mounted to a surface at wall penetration of a plastic pipe. The collar includes a first collar half and a second collar half, having corresponding end portions which are connected to each other. A fire resistant foldable cap is circumferentially connected to the collar for closing off the penetration location when the pipe is collapsed. In case of a fire an actuation assembly moves the fire resistant foldable cap over the penetration location to close it off. The collar is a fold-out collar in which said corresponding ends of the first and second collar halves are hingedly connected to each other to be moveable from a folded state, in which the second collar half substantially overlaps the first collar half, to a folded out state, in which the first collar half and the second collar half form a ring shaped collar.
