A series of fire tests in several typical office occupancy configurations were conducted in order to address the use of quick response sprinkler technology. These tests included 1) heat release rate tests, 2) compartment fire tests and 3) a large office test. The heat release rate tests were designed to characterize the burning rates of a computer work station and open shelf office storage. The compartment fire tests were designed to examine the effectiveness of quick response sprinklers in typical office fires involving a computer work station or an open office module. Measurements of heat release rate, air temperature, and the concentration of oxygen, carbon monoxide and carbon dioxide were taken. A large office test configured with multiple open office modules was conducted to verify the compartment test results and examine the possibility of multiple sprinkler activation. Measurements of air temperature and the concentration oxygen, carbon monoxide and carbon dioxide were taken.
