In the conventional configuration, every time the fire restoration switch 4 is pressed, all the state change information detection circuits are restored to operation, and then all the state change information is provided in the receiver 1 (not shown). However, if the fire recovery switch 4 is pressed during the adjustment work in the initial stage of adjustment of the self-fire alarm system, enormous amount of status change information is displayed on the display device regardless of whether it is necessary or not. Therefore, it is necessary to search only the information necessary for the adjustment from the state change information, and the search work requires a great deal of effort, so that the adjustment work is 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 related to the control of the smoke prevention terminal of the fire alarm system,
Other configurations are omitted in the drawing. In the figure, the receiver 11
Is a fire signal detection device 13 that detects a fire signal output from the sensors 12a and 12b, a smoke emission / exhaust smoke interlocking control device 14 that outputs a smoke emission / exhaust smoke interlocking control signal in conjunction with the detection of the fire signal, and The smoke-proof / exhaust-proof interlocking control device 14 and the smoke-proof / exhaust-gas-exhaust terminal are provided between the smoke-proof / exhaust-gas-proof terminal and the smoke-proof / interlock stop device 15 for controlling transmission of the smoke-proof terminal control signal to the smoke-proof terminal. Further, the smoke prevention / interlocking stop device 15 operates the receiver operation unit (not shown) to keep the smoke prevention / interlocking stop device 15 in the interlocked stop state (transmits the smoke prevention terminal control signal to the smoke prevention terminal). It is provided with the interlocking stop switching circuit 16 for switching to a non-operational state) or an interlocking state (a state in which the smoke-exiting smoke-proof terminal control signal is transmitted to the smoke-exiting smoke-exhaust terminal).

The smoke emission control function of the receiver 11 will be described. The fire signal detection device 13 detects a fire signal output from the detectors 12a and 12b, and the smoke / exhaust smoke emission interlocking control device 14 operates in conjunction with the detection operation to output the smoke emission / exhaust smoke control signal. The smoke exhaust terminals 17a and 17b come to operate. However, the smoke prevention / exhaust gas interlocking control device 14 interposed between the smoke prevention / exhaust gas interlocking control device 14 and the smoke prevention / exhaust gas terminals 17a, 17b is in the interlocking stopped state (the smoke prevention / exhaust control signal is sent to the smoke prevention / exhaust terminals 17a, 1b).
7b), even if the smoke prevention / exhaust ventilation interlocking control device 14 is operating,
17b does not work. Originally, the smoke-proof and smoke-proof interlocking device

5 is switched to the interlocking stopped state (the state in which the smoke proof terminal does not transmit the smoke proof terminal control signal).

FIG. 7 shows an example of an operating portion of a conventional self-warming system. In the figure, reference numeral 18 denotes a push-button type smoke-proof and smoke-proof interlocking stop switch provided corresponding to a predetermined smoke-proof and smoke-proof terminal. The state of the smoke-proof and smoke-proof interlocking stop device 15 can be switched by control. In the example shown in FIG. 7, an LED is built in the smoke prevention / exhaust gas interlocking stop switch 18, and the state of the smoke prevention / exhaust gas 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-proof / exhaust-gas-exhaustion interlocking device 15 and the smoke-proof / exhaust-gas emission interlocking controller 14 and the lighting states of the LEDs), when the LED is on Indicates that the smoke prevention / interlocking stop device 15 is set to the interlocking stop state by the smoke prevention / interlocking stop switch 18. Conversely, when the LED is off, the smoke prevention / interlocking stop device 15 is shown. Indicates that it is not operating and is in a linked state.

However, in such a configuration, Table 1 of FIG.

Instead, all the information is displayed on the display device, and it is necessary to retrieve only the information necessary for adjustment from the state change information, which requires a great deal of effort, and the adjustment work is performed efficiently. There was a problem that it was not understood.

Further, in the self-fire alarm system shown in FIGS. 6 and 7, when the smoke-proof and smoke-exiting interlocking stop device 15 is set to the interlocking stop state by the smoke-exiting and smoke-exhaust interlocking stop switch 18, Since it is not possible to determine the operating state of the interlocking control device 14, even if the smoke prevention / exhaust gas emission interlocking control device 14 is operating, the smoke emission / exhaust gas emission interlocking stop is performed from the receiver operation unit via the interlocking stop switching circuit 16. The device 15 is returned to the interlocked state as an inoperative state, and the smoke-proof and smoke-proof terminals 17a, 1
