PROBLEM TO BE SOLVED: To intelligibly display to effectively practically use history information, in a display device for a disaster prevention system. SOLUTION: This disaster prevention display 10 has a CRT 11 displaying conditions inside a fireproof area on the basis of event information sent from a terminal device, and a history storage part 23 storing the event information as the history information. When an event occurs, the CRT 11 displays an event notification screen (a fire alarm screen 60) showing the terminal device generating the event information in a position corresponding to an actual set position in an image picture in a state different from symbols of the other terminal devices. When the prescribed event information is selected from the history information, the CRT 11 displays a replay display screen 50 or an interlocking replay display screen 80 displaying the corresponding terminal device nearly similarly to the event notification screen.
