Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire alarm device for a housing complex, which monitors a fire in a housing complex such as a high-rise apartment provided with a housing information panel and an intercom for each dwelling unit.

[0002]

2. Description of the Related Art Conventionally, in an apartment house such as a high-rise condominium, for example, a housing information board as shown in FIG. 5 is installed in each dwelling unit to monitor the inside of the dwelling unit for abnormalities such as fire and gas leakage. I have to. In FIG. 5, reference numeral 1 denotes a house information board, which is installed in a dwelling unit and connected with a fire detector 2, a gas leak detector 3 and an emergency push button device 4. Fire detector 2,
Signals from the gas leak detector 3 and the emergency push button device 4 are received by the fire reception unit 5, the gas reception unit 6, and the emergency reception unit 7,
The received signal is given to the CPU 8.

For example, when a fire reception signal is obtained, the CPU 8 activates the display unit 9 to display a fire, and activates the voice synthesis unit 10 to output a voice signal of a voice message, for example, "Woo fire." Then, the amplifier 11 supplies the speaker 12 with a voice alarm. Here, an intercom master unit 15 is provided integrally with or in the vicinity of the house information board 1 so that an intercom call can be performed with an intercom slave unit (intercom slave unit) 16 installed at the entrance of the dwelling unit. .

Since the intercom sub-unit 16 is provided with a speaker for communication, an outdoor alarm interface 18 is provided on the house information board 1, and the CPU 8 drives the relay 14 by the transistor 13 when a fire is detected. By switching the relay contact 14a from the intercom master unit 15 side to the outdoor alarm interface 18 side, the voice synthesis unit 1
The audio signal from 0 is supplied to the speaker of the intercom subunit 16 so that the intercom subunit 16 also outputs an alarm sound indicating a fire.

By the way, as a fire alarm device installed in an apartment house equipped with such a house information board 1, it is installed in a common area such as a fire signal from a fire detector connected to the house information board 1 or a corridor. When a fire signal from a fire detector or transmitter is received by the receiver, the receiver rings the main bell to give a fire alarm, and the district bell installed on each floor is also run to alert the fire. I try to let you know.

[0006]

However, in the conventional fire alarm device for an apartment house, the alarm sound is output by the intercom subunit of the dwelling unit where the fire occurs and the ringing of the area bell by the original fire alarm device occurs. Since it is done individually, even if the alarm sound is output from the intercom subunit of the fire occurrence dwelling unit when the area bell of the fire alarm device rings, the output of the alarm sound itself has much meaning. Absent.

In addition, even if the area bell stop switch is still turned on at the receiver and the area bell does not ring when a fire is received, the output level of the alarm sound from the intercom subunit of the fired dwelling unit is still high. Since it is not so large, it is not sufficient as a warning for the entire fire floor. That is, in the conventional device, the original alarm of the fire alarm device by the ringing of the area bell and the alarm by the output of the alarm sound from the housing information panel using the intercom subunit are considered separately, and when both are present. There is a problem that the voice alarm using the intercom sub-unit of the housing information board cannot be fully utilized without considering the alarm form.

The present invention has been made in view of such conventional problems, and effectively utilizes an intercom sub-unit equipped with an interphone speaker installed in each dwelling unit to provide a sound from a fire alarm device. It is an object of the present invention to provide a fire alarm device for an apartment house that can appropriately give an alarm.

[0009]

To achieve this object, the present invention is constructed as follows. First of all, the present invention is an assembly including an intercom sub-unit installed in each dwelling unit and having a speaker for intercom communication, and a central monitoring panel for receiving a fire signal from a fire detector installed in a warning area to give an alarm. Intended for residential fire alarm systems.

In the present invention as such a fire alarm device for an apartment house, speaker input switching means for switching the speaker input to the intercom subunit of each dwelling unit from the call signal input from inside the dwelling unit to the signal input from the outside. On the other hand, the central monitoring panel is provided with switching control means for controlling the speaker input switching means of the intercom sub-unit to switch the speaker input to the external signal input when a fire is received, and the switching control means switches to the external signal input. And a voice synthesizing means for sending a voice signal to the speaker to output an alarm message.

Here, the switching control means of the central monitoring panel switches the speaker input means of the intercom subunit on the fire floor and the floor immediately above to an external signal input to output the voice signal from the voice synthesizer from the speaker. Provide a circuit. In addition, a speaker is installed on the fire alarm board (self-report board) installed in common areas such as corridors, and when the central monitoring board receives a fire, the speaker of the fire alarm board installed on the fire floor and the floor immediately above. A voice signal is sent from the voice synthesizing means to output a warning message.

Further, the voice synthesizing means is configured to output a voice signal of a voice message including a fire occurrence location.

[0013]

According to the fire alarm system for an apartment house of the present invention having such a configuration, when a fire is received by the central monitoring panel having a function as a fire receiver, the conventional district bell ringing will take place. In addition, for example, the speaker of the intercom sub-units installed in the dwelling units on the floor where the fire occurred and the floor directly above the floor output a voice message indicating the fire occurred by an alarm sound all at once. You can take action.

Next, the processing operation of the present invention according to the embodiment of FIG. 2 will be described with reference to the processing flow of FIG. Here, FIG.
For example, a case where the fire alarm system of the present invention shown in FIG. 4 is installed in a five-story apartment house having 10 dwelling units on each floor as shown in FIG. In FIG. 3, assuming that a fire has occurred in room 103 on the first floor as shown in step S1, the fire detector 2 installed in room 103 is activated in step S2, and the fire reception in the repeater 20 is received in step S3. Is done. The result of reception by the repeater 20 is transmitted to the central monitoring panel 24 and the housing information panel 1 as shown in steps S4 and S5, and a fire alarm is issued respectively.

At this time, in the central monitoring board 24, as shown in step S6, the voice synthesizing circuit 33 is activated, and at the same time, the power amplifier 34 is activated, and a voice message indicating the occurrence of a fire, for example, a voice of "Woo fire" Output a signal. At the same time, as shown in step S7, the switching control signal according to the diode matrix of the matrix circuit 35 is output. At this time, the relay contact 11 of the matrix circuit 35 is closed due to the fire on No. 103 on the first floor,

FIG. 4 shows the output state of the alarm sound from the speaker SP of the intercom sub-unit 16 of each dwelling unit when a fire breaks out in room 103 on the first floor of FIG.
The alarm message will be output simultaneously from the two intercom slave speakers on the first floor and the upper floor.
In this audio output state of the alarm message from the intercom subunit, although the audio output from the speaker 22 of each one of the intercom subunits 16 is not so large, it is sufficiently heard at the location where the adjacent intercom subunit is installed. Since such speaker output is performed simultaneously from the speakers of all intercom subunits, it is possible to reliably hear the alarm message by voice output regardless of the location of the fire floor or the floor directly above. .

In the above-mentioned embodiment, the warning message "Wooh is a fire" is output, but since the fire floor is known in the central monitoring panel 24, the location of the fire is indicated. It is desirable to output the voice message shown, for example, "Woooo is on fire." Further, in addition to a voice message for informing a fire, an appropriate voice message for instructing evacuation guidance or initial fire extinguishing, and further for informing a fire department or the like may be combined.

If a warning message is output by voice due to a false report, an operation from the central monitoring board 24 may output a voice message indicating that the report is false. Furthermore, in order to ensure that the voice output from the speaker of the intercom sub unit is routinely used to ensure the voice output in the event of a fire, it is possible to use broadcast output such as hourly output and appropriate notification.

Furthermore, although the above-described embodiment is described as an example when a fire is received, the speaker of the intercom sub-unit is also used at the time of a gas leak or an emergency such as theft in the same manner as when a fire is received. It is possible to output a warning of the voice message used.

[0034]

As described above, according to the present invention, it is possible to promptly and appropriately notify the occurrence of a fire by changing the fire alarm, which was conventionally performed by ringing a bell, to a voice alarm by a voice message. . In addition, a more appropriate response can be taken by outputting an alarm of a voice message including information such as a fire occurrence location. In addition, it is necessary to install a speaker dedicated to the fire alarm device for each dwelling unit in order to output a voice alarm when a fire is received using the speaker of the intercom door device for intercom provided in the housing information board. It can be saved and the equipment cost can be significantly reduced by using it together with the intercom subunit.

Furthermore, since the voice signal is sent from the voice synthesizing means provided on the central monitoring board to output the alarm message all at once, it is not difficult to hear even if the alarm message is output from a plurality of speakers.
