Abstract
A correction system for a detector of a fire system, the correction system comprising: a calculation unit operable to calculate the n+1th order differential (wherein n is a whole number and n≥1) of an output of a sensor of the detector with respect to time; a measurement unit operable to measure the n+1th order differential to determine the extent of an initial curvature of a line of the output of a sensor of the detector with respect to time and a correction unit operable to correct an output of the sensor based on the measurement. The correction system can compensate for impairment of the sensor and results in more accurate sensor readings (and accordingly a more useful fire system).
