In FIG. 1, the receiver 1 includes a CPU 2, a communication control device 3 for performing multiplex transmission, a fire recovery switch 4, and a fire recovery device 6 for transmitting a fire recovery command to the repeater 5.
Further, the repeater 5 includes a CPU 7, a communication control device 8 for performing multiplex transmission, and state change information (for example, a fire occurrence,
It comprises a state change information detection circuit 9a, 9b for detecting the occurrence of gas leakage, smoke prevention terminal operation, various alarm operations, and a fire recovery device 10 for restoring the operation of the state change information detection circuits 9a, 9b. . When the fire recovery switch 4 is pressed in the receiver 1 configured as shown in FIG. 5, a fire recovery command is transmitted from the fire recovery device 6 to the repeater 5 via the communication control device 3. When the repeater 5 receives the fire recovery command via the communication control device 8, the fire recovery device 1
By 0, the operation of the state change information detection circuits 9a and 9b was restored. In the conventional configuration, every time the fire recovery switch 4 is pressed, the operation of all the state change information detection circuits is restored, and then all the state change information is displayed on a display device (not shown) provided in the receiver 1. When the fire recovery switch 4 is pressed during the adjustment work at the initial stage of the adjustment of the self-fire alarm system, a huge amount of state change information is displayed on the display device, regardless of whether it is necessary or unnecessary. It was necessary to search only the information necessary for adjustment from the state change information, and the search work required a great deal of work, so that the adjustment work was not performed efficiently. . Next, a different example of the self-fire alarm system will be described with reference to FIG. FIG. 6 is a configuration diagram showing only the configuration relating to the control of the smoke prevention terminal of the self-fire alarm system,
The other components are not shown. In the figure, the receiver 11
Includes a fire signal detection device 13 for detecting a fire signal output from the sensors 12a and 12b, a smoke control device 14 for outputting a smoke control signal in response to detection of the fire signal, The apparatus is provided with a smoke-exhaust interlock control device 14 and a smoke-exhaust interlock stop device 15 interposed between the smoke-exhaust terminal and controlling transmission of a smoke-exhaust terminal control signal to the smoke-exhaust terminal. In addition, the smoke prevention smoke interlocking stop device 15 operates the receiver operation unit (not shown) to set the smoke prevention smoke interlocking stop device 15 to the interlock stop state (transmits the smoke prevention terminal control signal to the smoke prevention terminal). An interlock stop switching circuit 16 is provided for switching to a non-interlocked state or an interlocked state (a state in which a smoke prevention terminal control signal is transmitted to the smoke prevention terminal). The smoke control operation of the receiver 11 will be described. The fire signal detection device 13 detects the fire signal output from the detectors 12a and 12b, and the smoke prevention and smoke interlocking control device 14 operates in conjunction with the detection operation, and outputs a smoke prevention and smoke control signal. The smoke exhaust terminals 17a and 17b operate. However, the smoke and smoke interlocking stop device 15 interposed between the smoke and smoke interlocking control device 14 and the smoke and smoke prevention terminals 17a and 17b is in an interlocked state (when the smoke and smoke control terminal 17a, 1
7b), even if the smoke emission control device 14 is in operation, the smoke emission terminals 17a,
17b does not work. Originally, smoke prevention interlocking stop device 15
In the initial stage of adjustment of the self-fire alarm system, when a fire is actually detected by the detectors 12a and 12b when no fire has actually occurred, the smoke prevention terminal 17a,
In this case, the interlock stop switching circuit 16 operates the receiver operation unit of the receiver 11 to operate the intermittent smoke prevention interlock stop device 1.
5 is switched to an interlocking stop state (a state in which a smoke prevention terminal control signal is not transmitted to the smoke prevention terminal). FIG. 7 shows an example of an operation unit of a conventional self-fire alarm system. In the figure, reference numeral 18 denotes a push-button type smoke emission interlocking stop switch provided corresponding to a predetermined smoke emission prevention terminal. By operating the smoke emission interlocking stop switch 18, the interlock stop switching circuit 16 is activated. By controlling, the state of the smoke prevention and smoke interlocking stop device 15 can be switched. In the example shown in FIG. 7, an LED is built in the smoke prevention and smoke interlocking stop switch 18, and the state of the smoke and smoke prevention interlocking stop device 15 can be identified by the lighting state of the LED. That is, as shown in Table 1 of FIG. 7 (a table showing a correspondence relationship between the operating states of the smoke-prevention interlocking stop device 15 and the smoke-prevention interlocking control device 14 and the lighting states of the LEDs), the LED is turned on. Indicates that the smoke and smoke interlocking stop device 15 is set to the interlocking stop state by the smoke and smoke interlocking stop switch 18. Conversely, when the LED is off, the smoke and smoke interlocking stop device 15 is turned off. Numeral 15 indicates that it is not operating and is in the linked state. However, in such a configuration, Table 1 in FIG.
As shown in (2), when the smoke emission interlocking stop device 15 is set to the interlocking stop state by the smoke emission interlocking stop switch 18, the operation state of the smoke emission interlocking control device 14 cannot be determined. Even though the smoke and smoke interlocking control device 14 is operating, the smoke and smoke interlocking interlocking device 15 is returned to the interlocked state by the receiver operation unit via the interlocking stop switching circuit 16 as an inactive state. Smoke exhaust terminals 17a, 17
Since there were many troubles that caused b to operate erroneously, the actual situation was that the adjustment work was not performed efficiently. [0009] As described above, in the self-fire alarm system shown in FIGS. 6 and 7,
Smoke prevention interlocking stop device 15 is operated by smoke prevention interlock
In the case of the interlock stop state, the operation state of the smoke and smoke interlocking control device 14 cannot be determined. From the unit via the interlocking stop switching circuit 16, the smoke prevention interlocking stop device 15 is returned to the interlocking state as an inactive state, and troubles that cause the smoke prevention terminals 17a and 17b to operate erroneously frequently occur. There was a problem that the adjustment work was not performed efficiently.
