RP-677 -- Effect of Automatic Sprinkler Protection on Smoke Control Systems PDF

A series of experiments on the interactions of sprinklers with shielded fires were conducted at the National Research Council of Canada, National Fire Laboratory (NFL) facility near Ottawa, Ontario. The project was jointly funded by the American Society of Heating, Refrigerating and Air Conditioning Engineers, Inc. and the National Research Council of Canada. The objective of this research was to measure the effects that water spray from automatic sprinklers has on the conditions of temperature, pressure, oxygen, carbon dioxide and carbon monoxide levels in a building under fire conditions, and to assess the effect that changes in these conditions might have on the performance of a zoned smoke control system. The effects were measured for standard and quick response automatic sprinklers in an assumed office occupancy, and for a range of conditions of fire severity.
