Utilizing a zone model and a ceiling-jet model, a simple calculation method for predicting heat detector's response is presented. The parameters are the floor area and the ceiling height of the room, the radial distance of the detector from the fire axes, time history of the heat release rate of the fire, and the response characteristics of the detector. Application of the RTI-C model is discussed and a method utilizing two RTI's, one for the sensor element and the other for the detector body, is introduced. The method using two RTI's shows better results than the original RTI-C model, which is derived for predicting the response of sprinkler heads. In addition, a calculation method for predicting the response of rate-of-rise heat detector is presented. Overall performance of the prediction method is tested with experiments.
