Method & apparatus for retarding fire in a telecommunications box

摘要

Retarding a fire condition of a telecommunications component mounted on a module to be inserted into a telecommunications box is provided. The module may have a planar surface having a first side and a second side generally opposed to the first side. A ventilator provides a cross air flow generally in a direction from the first side to the second side. A first opening in the telecommunications box in an area adjacent of the first side of the planar surface forms a substantial portion of the cross air flow emanating from the first side. A second opening in the telecommunications box arranged in an area adjacent to the second side of the planar surface exhausts the cross flow air, such that the cross flow air sub-stantially retards the fire condition. An air flow guide is provided to simulate an air resistance of a module.
