SENSITIVITY TEST METHOD OF SMOKE SENSOR, SENSITIVITY TEST DEVICE AND SMOKE SENSOR

摘要

PROBLEM TO BE SOLVED: To perform inspection according to characteristics of individual sensors without installing a test terminal to the sensor, and installing a smoke generator to a test device.SOLUTION: A sensitivity test method determines the sensitivity of a smoke sensor which comprises smoke density detection means, a function for outputting a fire generation issue signal when detected smoke density is not lower than a prescribed value, a terminal which can output the fire generation issue signal, a function for determining whether or not the smoke density is not lower than the prescribed value on the basis of a value which is obtained by adding a value inputted from the outside to an output value of the smoke density detection means. After imparting a determination execution command which indicates whether or not the prescribed value and the smoke density are not lower than the prescribed value to the smoke sensor, the sensitivity test method repeats determination indicating whether or not the fire generation issue signal is detected by the smoke sensor, and determines the sensitivity of the smoke sensor. When repeatedly performing the determination, a value which is higher than a working range minimum value being a lower limit value of a normal fire determination range is sequentially sent to the smoke sensor from a value which is lower by a prescribed step value one by one by a step value.
