Hereinafter, this alarm processing is performed by the fire alarm receiver 2 and the voice alarm controller 3 and the relay unit C
1 to Cn.

First, the processing in the fire alarm receiver 2 and the voice alarm controller 3 will be described with reference to the flowchart shown in FIG.

The fire alarm receiver 2 is provided with each of the repeater units C1 to C1.
A transmission signal is exchanged with Cn, and it is checked whether or not a transmission signal received from each of the repeater units C1 to Cn includes a signal indicating the occurrence of a fire (step S1).

The fire alarm receiver 2 is connected to each of the repeater units C1 to C1.
If the transmission signal from Cn includes a transmission signal indicating the occurrence of a fire, the transmission signal recognizes that a fire has occurred (step S2), and analyzes the situation of the fire from the signal content indicating the fire. The analysis result is output to the voice alarm controller 3 as detection information (step S3).

The voice alarm controller 3 includes the fire alarm receiver 2
Based on the detection information from, a voice alarm corresponding to the fire condition is selected for each of the repeater units C1 to Cn (step S4), and the selected repeater units C1 to Cn are selected.
A voice information identifier corresponding to each voice alarm is generated, and the voice information identifier and the repeater identifier are output for each of the repeater units C1 to Cn (step S5).

Next, the processing in each of the repeater units C1 to Cn will be described with reference to the flowchart shown in FIG.

Each of the repeater units C1 to Cn determines whether or not a transmission signal is transmitted from the voice alarm controller 3,
Always check (step Q1), and when a transmission signal is sent, a repeater identifier is extracted from the transmission signal and whether the repeater identifier in the transmission signal matches the repeater identifier assigned to itself. It is checked whether it is (step Q2).

That is, each of the repeater units C1 to Cn
Converts the repeater identifier in the transmission signal into a repeater identification decoder 2.
In step 3, it is checked whether the decoded repeater identifier matches its own repeater identifier.

If the repeater identifier in the transfer signal does not match the repeater identifier assigned to itself at step Q2, the process returns to step Q1 to perform the same processing.
If they match, it is checked whether the command signal in the transmission signal is a restoration command or a rewriting command (step Q
3).

In step Q3, when the command signal is a restoration command, the speech information identifier is decoded by the speech information identification decoder 22, and speech data corresponding to the decoded speech information identifier is extracted from the speech data ROM 25, and the speech restoration processing is performed. Output to the unit 26 (step Q4). The extracted audio data is restored by the audio restoration processor 26,
Then, the signal is amplified at step 7 and output from the speaker B1 (step Q5).

That is, each of the repeater units C1 to Cn
When there is a transmission signal and the repeater identifier of the transmission signal matches its own repeater identifier, it checks whether the command signal is a restoration command, and when the command is a restoration command, it corresponds to the voice information identifier of the transmission signal. The voice data is read from the voice data ROM 25, and after the content of the voice data is restored, the voice data is output.

As described above, the voice data ROM 25 can store voice data having different contents for each of the repeater units C1 to Cn. Each repeater unit C1
To Cn are designated by audio information identifiers.

As the contents of the audio data, for example,
As a combination of the location and the information of the fire occurrence, "Fire has occurred on this floor. Please evacuate immediately according to XX.""Fire has occurred on the □□ floor. Evacuate immediately according to XX." Please do. "" A fire has occurred near here. Please evacuate immediately according to XX. "" A fire has occurred near □□. Please evacuate immediately according to XX. " A fire broke out on the lower floor. Please evacuate immediately according to XX. "" A fire broke out in the room. Please evacuate immediately according to XX. ""The aisle ahead is full of smoke and is dangerous. Please go around.""This stair is full of smoke and it is dangerous. "Please smoke in this room Is full and dangerous. Please do not enter. "" Room XX is full of smoke and dangerous. Please do not enter. "" This passage is full of smoke. Dangerous. Do not enter. "" The stairs are full of smoke and dangerous. Do not enter. "

Further, as information contents of the evacuation route, there are "Please evacuate using these stairs" and "Please evacuate using this passage".

Also, as the information content of the malfunction, "The fire on this floor was malfunction." "The fire on the floor was malfunction." "The fire near this was malfunction. "The fire near the □□ was a malfunction." "The fire on the floor below this was a malfunction." "The fire in the □□ room was a malfunction."

The symbols □□ and OO mean words whose contents are changed according to the installation status of each of the district units T1 to Tn.

Therefore, each of the repeater units C1 to Cn
By appropriately selecting the audio data stored in the audio data ROM 25, the respective repeater units C1 to Cn
It is possible to give a warning by sound with appropriate contents to the floor, ridge or block where is installed, and to encourage appropriate evacuation behavior.

The voice data in the voice data ROM 25 may be selected in combination as appropriate, and the voice may be output in the order of the selection. In this case, a more appropriate alarm can be issued. At the same time, the capacity of the audio data ROM 25 can be reduced.

If the command signal of the transmission signal is a rewrite command in step Q3, the voice data in the voice data ROM 25 is rewritten by the voice data included in the transmission signal (step Q6).

That is, each of the repeater units C1 to Cn is sent from the voice alarm controller 3 without going to the place where all the repeater units C1 to Cn are installed.
The content of the audio data in the audio data ROM 25 is changed according to the situation where each of the repeater units C1 to Cn is installed.
It can be written or rewritten as appropriate, and the content of the audio data can be made simple and easy to make it more appropriate.

In the example of the voice data described above, the alarm at the time of fire occurrence and the case of its malfunction are shown, but it goes without saying that the present invention is not limited to this. For example, when a fire is extinguished, sound data for notifying recovery may be stored in the sound data ROM 25 and notified.

In the above embodiment, the case where the present invention is applied to the fire alarm device 1 has been described. However, the present invention is not limited to this, and can be applied to, for example, an earthquake alarm device.

In the above embodiment, both the sensors P1 to Pn and the speakers B1 to Bn as alarms are connected to each of the repeater units C1 to Cn. However, the present invention is not limited to this. The devices P1 to Pn include speakers B1 to
Bn may be connected to a different repeater, or may be directly connected to the fire alarm receiver 2 without going through the repeater. The point is that appropriate audio data is stored for each of the repeater units C1 to Cn, and a sound alert corresponding to the occurrence of the abnormality is issued by a speaker B1 as an alarm connected to each of the repeater units C1 to Cn. -Bn as long as it can be generated.
