Further, the timer 33 starts a time measuring operation when the power is turned on.

  As shown in FIG. 4, in the mode change process, first, after reading the data (initial value) in the internal memory in step S1, it is determined whether or not a predetermined time (for example, 30 seconds) has passed (step S2). When a predetermined time (30 seconds) elapses, the transition is made from the initialization mode to the normal operation mode.

During the operation mode shifted from step S2, if it is determined that the setting switch button 19E has been operated for a long time (for example, for 3 seconds) (Yes) except at the time of fire alarm as in step S3, setting on the site is possible. Transition to setting mode (site).
In this setting mode, various settings can be performed by operating one of the operation buttons 17A to 17D provided on the information display unit 16 and the display operation unit 17.

Next, display control of the information display unit 16 and lighting control of the information lamp 18b of the information operation unit 18 performed by the information display control board 31 in the operation mode will be described with reference to the flowchart of FIG.
When the operation mode is started, the information display control board 31 first determines whether or not event occurrence information has entered from the main control board 21 of the main function unit 20 (step S11). If it is determined that the event occurrence information has entered (Yes), the process proceeds to step S12 and information (text data representing the type and content of the fire or abnormality) is stored from the memory (EEPROM) 23c. Read. Subsequently, the information lamp 18b of the information operation unit 18 is blinked (step S13).

  Next, it progresses to step S14, it is determined whether the information button 18a was pressed, and if it determines with it not being pressed (No), it will return to step S11. If it is determined in step S14 that the information button 18a has been pressed (Yes), the process proceeds to step S15, the information lamp 18b is changed from blinking to lighting, and the first text sentence is displayed on the information display unit 16.

  Thereafter, the process proceeds to step S16, and after resetting the timer and starting the time measuring operation, it is determined whether or not a predetermined time (for example, 5 seconds) set in advance has elapsed (step S17). If it is determined that the predetermined time (5 seconds) has not elapsed (No), the process proceeds to step S18, where it is determined whether or not the information button 18a has been pressed, and the information button 18a has not been pressed (No). If YES, the process proceeds to step S20 to determine whether or not the “OK” button 17D (or “RETURN” button 17C) has been pressed.

If it is determined in step S20 that the “OK” button 17D (or “return” button 17C) has been pressed (Yes), the process proceeds to step S21, and the first sentence (or one previous sentence) of the text with detailed contents is entered. Is displayed on the information display unit 16, and the process proceeds to step S22. If it is determined in step S20 that the “OK” button 17D has not been pressed (No), the process proceeds to step S22. In step S22, it is determined whether or not the shift button 17A or 17B has been pressed.
If it is determined that the shift button 17A or 17B has been pressed (Yes), the process proceeds to step S23 to display the next text sentence (or one previous text sentence) on the information display unit 16 and then to step S16. Return to, reset and start the timer, and repeat the above process.

On the other hand, if it is determined in step S17 that a predetermined time (for example, 5 seconds) has elapsed (Yes), or if it is determined in step S18 that the information button 18a is pressed (Yes) while the information lamp 18b is lit. In step S19, the information lamp 18b is turned off and the display of the information display unit 16 is stopped. Thus, control is performed such that the display of the information display unit 16 disappears when a predetermined time (5 seconds) has elapsed since the last button operation. Then, after the blinking of the information lamp 18b and the display of the information display unit 16 are stopped in step S19, the process returns to step S11 and waits for the next event occurrence signal.
In step S19, the display is stopped and the event occurrence information related to the event that has been displayed is erased from the memory on the information display control board 31. As a result, it is possible to avoid the occurrence of confusion in grasping the situation by redisplaying the event information (read information) already displayed due to an erroneous operation of the display operation unit 17 or the like. Further, by displaying the information, it can be noticed that a new event has occurred.

As described above, in this embodiment, when an event occurs, the information lamp 18b blinks, and when the information button 18a is operated while blinking, information related to the event that occurred (such as the type of fire or abnormality) is a character string. Therefore, the monitor can easily recognize what kind of event has occurred. Further, when the “OK” button 17D is operated during the display, detailed information on the generated event is displayed, so that the monitor can grasp the details of the generated event.
Furthermore, the information display is started by the operation of the information button 18a. During the information display, even if the next event occurs, the information lamp 18b is not blinked, and a predetermined time (for example, 5 seconds) has passed after the operation is finished. At this point, the information display unit 16 disappears and can be displayed when the next event occurs. Therefore, there is no possibility that the display is interrupted during the event content confirmation.
