[Problems that the invention attempts to resolve]

Conventional emergency alarm devices are configured as described above, so when performing maintenance and inspection work on equipment in the building being monitored, only the switch (4) is operated and the telephone line is connected only to this telephone (6). Connect the reporting device (1) and disconnect it from the telephone line, or operate the power switch of the reporting device (1) to turn off the power supply, and perform maintenance and inspection work to determine if the equipment is malfunctioning or abnormal. The detector (8a) e (8b) =... indicates that a failure or abnormality has occurred in the equipment.
(8c) was calculated incorrectly and an incorrect emergency call operation was performed.
However, by operating the switch (4), it is necessary to prevent the f - When disconnected from the telephone line, when regular reporting occurs every hour, for example every 24 hours, during maintenance and inspection work, the telephone tg1g is disconnected.
However, when I went to the country for maintenance and inspection work on the power supply, there was no time for the scheduled alarm operation every 24 hours, for example, and the emergency call system at the receiving 4G center was not working properly. There was a problem where it was incorrectly determined that a failure had occurred.

This invention was made to solve these problems.
Therefore, it is possible to prevent emergency notification operations from being performed incorrectly when a failure or abnormality has occurred in equipment due to maintenance inspection work, and to ensure that regular notification operations are performed normally even during maintenance inspection work. The purpose of the present invention is to obtain a complete emergency alarm system that will not cause an abnormality in the regular reporting operation and cause the emergency alarm system to be mistakenly determined to be out of order.

[Means for determining the problem kwI]

The emergency alarm device t according to the present invention includes a central processing circuit that issues an emergency report and a regular report indicating a failure or abnormality in equipment in a building to be monitored, and a setting switch that switches between a maintenance inspection work state and a monitoring operation state. At the same time, if the central processing circuit sets the setting switch to the maintenance/inspection work state, the maintenance/inspection work will cause a malfunction or abnormality to be detected in the equipment. The operation is suppressed and the regular reporting operation is not completely suppressed.

[Effect]

In this invention, when the setting switch is set to the monitoring operation state, an emergency call is made to report a failure or abnormality in equipment in the building to be monitored, and a regular call is made to report whether the reporting device itself is normal or not. If the other setting switch is set to the maintenance/inspection work state, the maintenance/inspection work may cause an erroneous emergency call operation that reports all equipment failures or abnormalities that are in the same state as the failure or abnormality. The scheduled notification operation is suppressed and controlled so that the regular notification operation is suppressed and the regular notification operation is suppressed and the regular notification operation is suppressed.

[Embodiments of the invention]

FIG. 1 is an internal circuit configuration diagram of a notification device (1) of an emergency notification device according to an embodiment of the present invention, and (9) to Q8+ are exactly the same as the above-mentioned non-conforming folds. The α sword is a setting switch, and is connected to input to the entire central Yx arithmetic processing circuit (121) whether it is in a maintenance/inspection work state or a monitoring operation state.

Next, the operation of the above embodiment will be explained. Setting switch Q4+
For example, when is set to open and monitoring operation status, the notification system [(11 is an emergency notification operation when a failure or abnormality occurs in the equipment in the building to be monitored, and a regular notification operation for a certain period of time, for example, every 24 hours). For example, if the zero setting switch α sword is closed and the maintenance/inspection work status is +n, the notification device (

), (8'b), . . .
Only regular hourly reports are made. In other words, if a maintenance worker sets the setting switch Cl41t to the maintenance and inspection work state in front of people during maintenance and inspection work, and when the maintenance and inspection work is completed, the setting switch α is set to the monitoring operation state, and then the maintenance and inspection work is performed. This prevents the equipment from being in the same state as a failure or abnormality, causing an erroneous emergency notification operation to be performed when a failure or abnormality has occurred in the equipment, and also to notify the operator at regular intervals, e.g. every 24 hours, during maintenance and inspection work. If the regular notification operation is performed normally, the switching device (4) must be operated to prevent erroneous emergency notifications of equipment failure or abnormality that will be in the same state as the failure or abnormality due to maintenance inspection work. By disconnecting the reporting device (1) from the telephone line or operating the power switch of the reporting device (1) to turn off the power, regular reporting wJfPF can be performed every hour, for example, every 24 hours, during maintenance and inspection work. Additionally, there will be no longer any lag in scheduled reporting times. This prevents the receiving center from incorrectly determining that the emergency notification device is malfunctioning due to abnormality in the regular notification operation due to maintenance and inspection work.

In addition, the above actual m? In IJ, if the setting switch α is set to the maintenance/inspection state, even if a failure or abnormality actually occurs in the equipment, the emergency notification operation will not be performed. 9. There are cases where there are equipment that does not reach the same state as a failure or abnormality during inspection work, or there are important equipment that requires an emergency call if a failure or abnormality occurs during maintenance and inspection work. Even if the setting switch is set to the maintenance/inspection work state, the entire monitoring circuit (9) receives a detection signal from a predetermined equipment failure or abnormality detector, such as a detector (8a). It is clear that even if the emergency notification operation for reporting equipment failure or abnormality is carried out normally without being suppressed, the same effect as in the above embodiment will be obtained.

〔Effect of the invention〕

As described above, according to the present invention, there is a setting switch that can be used to switch between the maintenance inspection work state and the monitoring operation state in the emergency notification device that makes an emergency report of a failure or abnormality in equipment in the monitored building. is provided, and when this setting switch is set to the maintenance/inspection f'l"chestnut state, the maintenance/inspection P'
I: The system is configured to suppress all emergency notification operations that notify all failures or abnormalities of equipment that are in the same state as a failure or abnormality, and to perform regular notification operation sound normal VC even during maintenance and inspection work. This has the effect of preventing false notifications of equipment failure or abnormality that are in the same state as the failure or abnormality, and preventing the receiving center from erroneously determining that the emergency notification device has failed.
