FIRE DETECTOR EQUIPPED WITH SENSOR

摘要

A fire detector is equipped with a sensor which detects physical quantities such as heat, light or smoke and which, in particular, stores the time when the fire detector responds or generates an alarm and also stores the output level of the sensor at such time and displays these stored data whenever required. It also stores successive output levels of the sensor at each of a series of predetermined time intervals along with the respective time values until the fire detector generates an alarm and displays these stored data whenever required.
