Since the regional sound lines B4 to B10 are not set in the interlocking table T, they are set corresponding to the sensor lines L1 to L10 as shown in the interlocking table T '.

As described above, if the measurement time after the key input exceeds a predetermined time, the operation mode is automatically shifted to the operation mode, so that the safety of the system can be ensured even if the manager is not nearby. Can be secured. Further, the interlocking table T set at the time of shifting to the operation mode is edited based on a predetermined rule, and the edited interlocking table T ′ is adopted. It is possible to prevent unnecessary sounding of the district sound device without outputting a sounding command signal.

When the mode is shifted to the operation mode, the interlocking table T may be adopted as it is without editing it as described above. Further, another example of the fire receiver of the present invention will be described with reference to FIGS. FIG. 5 is a diagram showing another example of the internal configuration of the fire receiver of the present invention. This fire receiver 1 'further includes a default interlocking table DT in addition to the above-described fire receiver 1, and the default interlocking table DT includes, as shown in FIG.

T, the fire signal is received via any of the detector lines L1 to L10, and all the local sound lines B1 to B
A ringing command signal is output to the reference numeral 10.

As described above, when shifting to the operation mode, the default interlocking table DT is adopted, and even if a fire signal is received via any of the sensor lines L1 to L10, all the local sound lines B1 to B10 Since the ringing command signal is output, the setting of the area acoustic line to output the ringing command signal is not leaked. The default linkage table DT is not limited to the one described above.

Here, when a predetermined time has elapsed since the key input, the fire receivers 1, 1 'are notified by the notification unit 13 and automatically switched to the operation mode. In this case, the security of the system can be ensured regardless of whether there is a manager or the like nearby. Further, the fire receivers 1 and 1 'may automatically shift to the operation mode after notifying the alarm unit 13 when the measurement time after the key input has passed a predetermined time by the notification unit 13. In this way, during the notification by the notification unit 13, if the manager or the like is setting the interlocking table, the manager or the like receives the setting and completes the setting. Before entering the operation mode,
The mode can be manually shifted by operating the mode changeover switch 11A, and unnecessary shift to the automatic operation mode can be prevented.
