In such a water discharge type fire extinguishing system 100, generally, a fire occurrence position and direction are specified from detection of a fire, and directions (turning) of the water discharge type heads 111a and 111b.
A series of water discharge preparation operations such as control are automatically performed, and a monitor present at the monitoring center 120 (hereinafter, referred to as a center monitor) confirms a fire occurrence state, a water discharge preparation state, and the like with the CRT monitor 122. By performing a water discharge operation by the central console 123, or by a monitor (hereinafter referred to as a local monitor) near the fire occurrence site performing a water discharge operation by the local manual consoles 112a and 112b,
Water is discharged from the water discharge heads 111a and 111b to the fire occurrence position.

Here, in the water discharge type fire extinguishing system 100, as described above, even if a relatively large space such as the arena or the hall 110 is used as the caution area,
Further, even if a relatively small space is used as the caution area, the central console 123 or the local manual console 11 may be used.
The water discharge heads 111a, 111b can be operated and controlled only from the side having the operation right to control the water discharge, either of 2a and 112b. In addition, the on-site manual consoles 112a and 112b are installed at positions where the operation state including the water discharge of the water discharge type heads 111a and 111b outside the guard area can be directly checked. In recent years, as described in JP-A-10-258136 and the like,
There is also known a water discharge type fire extinguishing system that automatically performs everything from detection of a fire to control of a water discharge direction of a water discharge type head and discharge of fire extinguishing water according to a predetermined logic.

On the other hand, among fire extinguishing equipment, the most common equipment is a fire hydrant device 3 as shown in FIG.
00, and it is obligatory to install it at a required location in a building based on the provisions of the Fire Service Law. As shown in FIG. 8, a general configuration of a fire extinguishing system to which the fire hydrant devices 300a and 300b are applied includes an indicator light 311a and a fire alarm transmitter 3.
12a, an automatic fire alarm system including an alarm bell 313a, etc. (also referred to as a self-fire alarm integrated panel), and a hydrant valve 3
Fire hydrant boxes 310a, 310 each having a hose storage section for storing a hose 14a, a hose 315a, a water discharge nozzle 316a, and the like.
b and a self-fire alarm receiving board 320 that receives a fire signal output when the fire alarm transmitter 312a of the self-fire alarm comprehensive panel is operated.
And a start push button 3 provided in the fire hydrant box 310a.
Start the pump by operating 17a, or
Based on the fire signal output when operating the fire alarm transmitter 312a of the self-fire alarm comprehensive panel, the pump is started by the transfer signal output from the self-fire alarm reception board 320, and is transmitted through the fire extinguishing pipe. A pump control panel 330 for supplying fire extinguishing water from the fire extinguishing water tank to each of the fire hydrant boxes 310a and 310b, a pump facility 350 including a pump 340 and the like are provided.

The criterion for installing such a fire hydrant device stipulates that the facility be installed so that each part of the facility is covered by a predetermined horizontal distance L from the fire hydrant devices 300a and 300b. For example, it is stipulated that the first hydrant should be provided within 25 m, and the second hydrant should be provided within 15 m, so that the fire hydrant devices 300a and 300b complement the guard area. It has become. However, when a relatively large space such as the above-described arena or hall is used as a guard area, the water discharge type fire extinguishing system alone has a limited fire extinguishing range, and may not be able to cover the entire guard area. Therefore, a configuration that complements each other by being used in combination with a fire hydrant device is adopted.

[0011]

In the water discharge type fire extinguishing system described above and the fire extinguishing system to which the fire hydrant device is applied, mutually complementary arrangements and the like are adopted so as to cover the entire area of the guard area. Since the fire extinguishing system and the fire hydrant device are installed separately and independently, there are the following problems. In other words, the conventional water discharge type fire extinguishing system and the fire extinguishing system to which the fire hydrant device is applied are both fire extinguishing facilities, but in the water discharge type fire extinguishing system, the self-standing type On the other hand, in the case of a fire hydrant device, the fire hydrant box and the fire hydrant box (housing) of the wall mount type and the wall mount type are installed separately from each other by different designs and constructions. Therefore, the number of man-hours required for design and construction is doubled, and depending on the structure and type of the building, the installation space, etc., there are problems such as many restrictions for installation and deterioration of the aesthetics of the facility.

[0012] Furthermore, fire was extinguished by operating a local manual console of a water discharge type fire extinguishing system, and fire extinguishing activities were performed. However, when the fire extinguishing situation was insufficient, a fire hydrant device had to be used. If an attempt was made to operate the local manual console of the fire extinguishing system to discharge water, but it was determined that fire extinguishing by the fire hydrant device was more effective, the local manual console and the fire hydrant device would be functionally functional. However, since little consideration has been given to the coordination of fire extinguishing activities, it is necessary to search for a fire hydrant device, and there is a problem that the initial fire extinguishing becomes insufficient. Therefore, the present invention aims to solve the above-described problems, and simplifies the design and construction of sprinkler equipment and a fire hydrant device using a water discharge type head and the like, and saves installation space,
In addition, the present invention provides a fire extinguishing facility capable of performing an efficient fire extinguishing activity by linking a sprinkler facility using a water discharge type head or the like and a fire hydrant device.

[0013]

According to a first aspect of the present invention, there is provided a fire extinguishing equipment in which a local manual operation section of a fire extinguishing system capable of controlling a water discharge operation by manual operation at least at a fire occurrence site is stored in a housing of a fire hydrant device. It is characterized by having done.
