A 70A fire sending switch SW8 is provided for displaying the alarm, and a display sending switch SW8 is provided for sending the display of the district display unit 28 displayed by the fire line indicator light 32 in the order of alarm occurrence. 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 receives the signal level of each sensor circuit Ai5. Along with monitoring, the addressable sensing B9 is 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 sends a control signal to ring the district bell 12. occurs. And when line interlocking is set, the corresponding smoke prevention equipment 13
Outputs a control signal to operate. Also, the 70 station buzzer 35 provided in the repeater 2 is sounded.

On the other hand, on the reception side 1 side, the address of the repeater 2 that made the interrupt request is indexed and the repeater 2 at that address is called. 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 reception fPi1, 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 ring the floor station buzzer 35 is transmitted to repeaters 2 other than the relevant repeater 2 by multiplex transmission, and a control command to ring the district bell 12 is multiplexed to the repeater 2 on the floor immediately above the alarm point. Transmit by transmission. When a fire alarm is confirmed and the fire determination switch SW2 is turned on, the main bell 14 will ring, and if the district bell 12 stops ringing and the smoke prevention interlocking stop is activated, a signal will be sent to forcibly cancel it. It is transmitted to each repeater 2 by multiplex transmission.

Further, when a general transmitter or a caller with an address (8!11) is activated, the same processing as a sensor alarm is performed, and the receiver 1 side displays a fire display and the location where the alarm occurred.

By the way, when an alarm is issued, the receiver 1 and the repeater 2 store alarm information for the same floor corresponding to the first alarm in the built-in line alarm display storage unit (not shown) in the order in which the alarm was issued. Based on the stored contents, the receiver 1 displays the building number, floor number, and district number of the alarm location as a message, and when the alarm is issued from the addressable sensor 9, it displays alarm scattering a, and a letter indicating the presence or absence of interlocking occurrence. is displayed on the district display section 15, and the receiver 1 is displayed on the repeater 2.
Similarly, the line number, floor number, district number, and message of the alarm location are displayed on the district display section 28. If a second alarm, third alarm, etc. occur in succession on the same floor, the alarm information is stored, and the receiver 12 displays the district number of the second alarm in the first alarm area. Part 171, and the third
The district number of each alarm is displayed on the second alarm district display section 172, and if there is a fourth alarm or more, the number of alarms will be exceeded, but this excessive state is indicated by lighting up the line display excess indicator light 40. Then, it is displayed that more areas on the same floor than the displayed number have issued alerts. When this display is displayed, the administrator operates the forwarding switch SW1° to display the displayed contents in the order of alarms in the alarm district display section 17. It can be sent from the area display unit 15, and from the area display area 17□ to 11. This display can be sequentially and cyclically advanced. Further, in the relay 2, when a second or higher alarm is issued, a fire line indicator light 32 provided corresponding to the alarm line is lit, and an excessive display light 29 is lit. When the excessive display light 29 is lit, by opening the door 42, you can confirm the alarm line by seeing the fire line indicator light 32 lit, and by operating the display forwarding switch SW, detailed information on the alarm lines can be displayed in the order in which the alarms were issued. This will be possible if the area is displayed on the district display section 28.

Now, if an alarm is issued on another floor, the receiver 1 stores the alarm information in the floor alarm display storage section (not shown), and also displays the line number and floor number in the floor alarm area display section 18 in the order in which the alarm is issued. ．． ,1
Display it on 8□. When the number of alarms exceeds the number displayed, the excessive state is indicated by lighting the dark display excess indicator light 41.

When the manager operates the send switch SW1, the alarm information in the floor alarm district display section 181 is first transferred to the line alarm display storage section (not shown), and at the same time, The contents are transferred to the floor alarm display storage section. and,
District display section 15, alert district display section 17. ．． At 172, the contents of the transferred line alarm display storage section are displayed. On the other hand, the contents of 18□ are displayed on the road alarm district display section 181, and the stored information of the floor alarm display storage section is called up and displayed on 182. When there is an alarm on another floor, the relay 2 also transmits the alarm information from the receiver 1, and when it is received, the floor fire indicator light 36 inside the door 42 is turned on and the alarm is sent to the other floor. It is possible to display that an alarm has been issued, and also to display the location of the lit repeater 2 on the district display section 28 by operating the floor fire sending switch SW.

[Effect of the Invention 1] As described above, the present invention includes a first district display section that displays detailed information such as the floor number and district number of the building where the first alarm was issued;
One or more alert area display areas that display alert area numbers on the same floor after the second alert in the order of alerts, and a first feed that sequentially sends the display contents of the front area display area and alert area display area Since the receiver is equipped with a switch and a switch, it is possible to grasp the spread of fire on the same floor without any confusion.
In addition, detailed information on the hot spot where the first alarm occurred can be obtained, allowing accurate travel to the scene.Also, the repeater can be alerted when an alarm is received from the sensor line connected to the repeater. The second section displays detailed information such as the floor number of the first alarm and the district number.
fire line indicator light provided corresponding to each connected detector line, and a second area display unit that sends the indications from the second alarm onwards displayed by the individual indicator lights to the second district display unit. Since the transmitter is equipped with a forwarding switch, the repeater can obtain detailed information on the location where the first alarm occurred, as well as the information after the tlS2 alarm. Since the information area can be displayed as described above, there is an effect that an optimal display effect can be obtained without confusion even though the amount of information has increased.
