The intercom 37 is equipped with a call button 38 and a call light 39.

Next, the operation of this self-fire alarm system in the alarm processing will be explained.

First, the receiver 1 sequentially calls each repeater 2 by multiplex transmission, and information is exchanged between the receiver 1 and the called repeater 2, and the repeater 2 changes the signal level of each sensor line 5. Along with monitoring, the addressable sensors 9 are sequentially called by multiplex transmission to exchange information.

At this moment, when the signal level of the sensor line 5 changes and an alarm is detected, the repeater 2 first interrupts polling by multiplex transmission with the receiver 1.
Then, the number of the sensor line 5 that issued the alarm and if the sensor is a sensor 9 with an address, the address of the sensor is stored. The repeater 2 displays the occurrence of a fire on the representative indicator light 27, displays the building, floor number, and district number of the corresponding building from the alarm line in numbers on the district display section 28, and at the same time controls the district bell 12 to sound. Generate a signal. When line interlocking is set, a control signal for operating the corresponding smoke prevention equipment 13 is output. It also makes the floor station buzzer 35 provided in the repeater 2 buzz.

On the other hand, on the receiver 1 side, the address of the repeater 2 that made the interrupt request is indexed and the repeater 2 of that address is
call. The called repeater 2 returns information such as the number of the alarm line and the address of the alarm sensor, as well as interlock operation information if there is an interlock setting. In the receiver 1, based on the returned information, the representative display section 16 displays the fire indication and whether or not there is an interlock, and the district display section 15 displays the location where the alarm was issued. In addition, when detecting that interlocking is set, receiver 1 indexes the interlocking table (other than alarm repeaters) and transmits a smoke prevention and exhaust control command for interlocking between repeaters to target repeater 2 by multiplex transmission. At the same time, a control command to cause the floor station buzzer 35 to sound to a repeater 2 other than the relevant repeater 2 is transmitted by multiplex transmission, and a control command to cause the district bell 12 to sound to the repeater 2 on the floor immediately above the alarm point. is transmitted by multiplex transmission. When a fire alarm is confirmed and the fire determination switch SW ₂ is turned on, the main bell 14 is sounded, and if the district bell 12 stops sounding and the smoke prevention interlocking has been stopped, it is forcibly canceled. The signals are transmitted to each repeater 2 by multiplex transmission.

In addition, when a general transmitter or a transmitter with an address 11 generates an alarm, the same processing as a sensor alarm is performed, and the receiver 1 side displays a fire display and shows the location of the alarm on the alarm area display section 17. indicate.

By the way, when an alarm is issued, the receiver 1 stores alarm information for the same floor corresponding to the first alarm in the built-in line alarm display storage unit in the order in which the alarm was issued, and based on the stored contents, the receiver 1 The building number, floor number, district number, and message of the alarm location, the number a of alarms from the addressable sensor 9, and the letter b indicating the presence or absence of interlocking are displayed on the district display section 15. Then, on the same floor, the second alarm, the third alarm...
If there are consecutive alarms, the alarm information is stored, and the district number of the second alarm is displayed in the first alarm district display section ₁₇₁ , and the district number of the third alarm is displayed in the second alarm district. The images are displayed on the display section ₁₇₂ . and the fourth
If there are more alarms than the number displayed, the number will exceed the number displayed.
This excess state is detected by lighting up the line indicator excess indicator light 40 to indicate that more areas on the same floor than the displayed number are reporting. When this display is displayed, the administrator operates the forwarding switch SW ₁₀ to send the display contents from the alarm district display section 171 to the district display section ₁₅ and from the alarm district display section ₁₇₂ to ₁₇₁ in the order in which the alarm was issued. It is possible. This display advancement can be performed sequentially and cyclically.

Now, if there is an alarm on another floor, the receiver 1 stores the alarm information in the floor alarm display storage section, and also displays the building number and floor number in the floor alarm district display section 1 in the order in which the alarm was issued.
Display on 8 ₁ and 18 ₂ . When the number of alarms exceeds the number displayed, the excess condition is indicated by the floor display excess indicator light 4.
1 is lit and displayed. When the administrator operates the forwarding switch SW ₁ , the alarm information in the floor alarm area display section ₁₈₁ is first transferred to the line alarm display storage section, and at the same time the contents of the line alarm display storage section are transferred to the floor alarm display section 181. The information is transferred to the information display storage section. Then, the contents of the transferred line alarm display storage section are displayed on the district display section 15 and the alarm district display sections 17 ₁ and 17 ₂ . Also, the contents of ₁₈₂ are displayed on the floor alarm district display section ₁₈₁ , and the stored information in the floor alarm display storage section is called up and displayed on the floor alarm display _{section 182} . FIG. 4 is a flowchart of the above-mentioned display operation.

In this way, the manager can easily grasp the extent of fire spread on the same floor simply by looking at the display contents of the district display section 15 and the alarm district display sections 17 ₁ and 17 ₂ .

[Effects of the Invention] As described above, the present invention includes a district display section that displays at least the floor number and district number of the building where the first alarm was issued, and a district display section that has a smaller display area than the district display section and displays the alarm district number of the same floor. One or more alert area display areas that display in the order of alerts, a line display excess indicator light that lights up when there are more alerts than the displayed number, and display information on the area display area and alert area display area in the order of alerts. 1st to be sent sequentially
