Existing methods for evaluating the performance of smoke and thermal detectors are reviewed. The levels of combustion gases, smoke, temperature and velocity likely to be produced in the European standard detector test fires are discussed, and this information is used to establish the operating conditions for a fire-emulator/detector-evaluator (FE/DE). The first generation FE/DE being developed by BFRL will handle multi-criteria spot-type detectors over the anticipated range of realistic operating conditions. Measurements in non-flaming test fires (TF 2 and TF 3) are described and example signatures are proposed for training the FE/DE to evaluate combination smoke/heat/gas detection systems.
