Abstract
A cable module device wherein a grommet plate closes the upper end of the module and, in the absence of high heat, seals and protects the module where, for example, a fire, located away from the module, results in cold smoke and water moving onto the module as from a sprinkler, fire hose, broken pipes, etc. on floor above or same floor as the module. The module is further provided with normally inert heat-sensitive plates which when triggered by a flame expand, to form a barrier in the module against passage therethrough of such excessive heat and flames.
