Rate-compensation type fire detector has not any of the drawbacks of the rate of rise type and the fixed temperature type ones. To my knowledge, however, there is no bulletin published of the theory of its operation.
With an object of giving guidance to the designing of this type of fire detectors, the fundamental theory is introduced.
Fundamental equations are given in this report representing the operation of the detector in the following two cases : 1. When the detector is heated by the air which rises in temperature at constant rate.
2. When the detector is heated by the air which rises in temperature discontinuously by a certain value at t=0.
