Abstract

PURPOSE:To make a printer, etc., unnecessary and to attain an efficiency displaying action by using fire displaying windows of a display operation panel and displaying the contents of an abnormality to occur in a prescribed period before the present and its occurrent time by switching operation at the time of a need. CONSTITUTION:When an abnormality occurs, a CPU 10 drives a displaying part 15, displays the type and the occurrence area of the abnormality, at the same time, inputs a signal from a clock part 17 and stores the type, the occurrence place and the occurrence time of the abnormality into an abnormality recording buffer of a storage part 11. Data in the buffer are erased after passing the prescribed period. A displaying action when an fire occurs is that a fire representative lamp lights up first and a buzzer rings. A fire occurrence area is displayed on a displaying window 151 and the number of fire reports is displayed on a displaying window 153 respectively. In this condition, when another fire is reported, its area is displayed on a window 152 and a 2 is displayed on the window 153 respectively. Further, when another fire occurs, a 3 is displayed on the window 153. Since the displays of the 151 and the 152 do not change, when the occurrence area of the third report is wanted to see, a display changing-over switch is operated, thus, the display of the window 152 is switched and the area is displayed.
