Then, in the water supply system, a foreign matter removal filter 12 is arranged on the upstream side of the pipe branching in the water supply device 1 to remove foreign matter contained in the water supplied to the house. Then, the tap water that has passed through the filter is branched and connected to the header box 3 pipe and the sprinkler pipe 10. Further, the header box pipe 3 and the sprinkler pipe 10 are connected to the respective connection ports arranged in the casing 17. And, between the sprinkler pipe 10 and the connection port,
A valve for controlling the opening and closing of the flow path according to an instruction from the control board 15 is provided.

Next, the operation of stopping the water sprinkling from the sprinkler for disaster prevention when the extinguishing of the fire is completed in the early stage will be described with reference to the operation flow chart of FIG. First, when a fire occurs (step S1), the disaster prevention sprinkler senses a temperature equal to or higher than a predetermined temperature (step S2), and the disaster prevention sprinkler head falls to start water spraying (step S).
3). At that time, the temperature sensor provided directly or in the vicinity of the sprinkler always detects the ambient temperature. When the user presses the switch that stops watering from the sprinkler in the operation panel (step S
In 4), if the temperature detected by the temperature sensor is equal to or lower than the predetermined temperature (step S5), the valve is operated in the direction of cutting off the water flow to the sprinkler side (step S6). Further, when the temperature sensor is equal to or higher than the predetermined temperature, the control board controls the water spray from the sprinkler so that the water is not stopped, so that the valve maintains the stopped state without changing the current position (step S7). Even if the switch is pressed to close the valve when the temperature is lower than the predetermined temperature (step S6), if the fire occurs again and the temperature sensor detects the temperature higher than the predetermined temperature (step S8), the valve is automatically opened again. Start watering in the open state. Therefore, it is possible to prevent water from being damaged after the fire is extinguished.

Here, this switch is provided on the operation panel as the water stop switch 13b of FIG. It is preferable to display in the operation panel that the water flow to the sprinkler side is stopped. Here, a mark is displayed beside the still water display in FIG. 2 to notify the user that the water flow to the sprinkler side is stopped.

When it is desired to stop watering even when the temperature detected by a temperature sensor provided directly or near the waterproof sprinkler is higher than a predetermined temperature, the switch is continuously pressed for a predetermined time (for example, 5 seconds) or more. It is advisable to operate the switch by changing the way of pressing the switch from the normal way of pressing the switch, such as continuing or pressing twice within a predetermined time (2 seconds).

In addition, a switch is provided on the operation panel that allows water to flow through the sprinkler piping when the disaster prevention sprinkler returns and remains in a water-stop state after shutting off the water discharge of the disaster prevention sprinkler. Is preferred. In particular, when the control board receives a signal that the disaster prevention sprinkler has been restored and is still in a water-stopped state after the disaster prevention sprinkler cuts off water flow, when the control board receives a signal from the disaster prevention sprinkler, It is preferable to open the valve in response to a signal from a switch that allows water to flow. In this case, this switch is the release switch 13a shown in FIG.

Next, when the recovery of the disaster prevention sprinkler 9 is completed after the completion of extinguishing the fire, the operation flow of water to the disaster prevention sprinkler will be described again with reference to FIG. After the completion of extinguishing the fire (step S10), the water stop switch 13b is operated as described above to stop the water in the disaster prevention sprinkler with the valve closed (step S11). In this state, even if the release switch is pressed by the user, if the signal indicating that the disaster prevention sprinkler keeps the water still does not come to the control board (step S12), the valve is connected to the disaster prevention sprinkler. Prevents water from being damaged even if the user accidentally presses the release switch even if the sprinkler has not finished recovering so that the water cannot be shut off. it can. Further, when the signal that the disaster prevention sprinkler has been restored comes to the control board, the user pushes the release switch (step S1).
By 3), the valve can move so that water can be passed to the sprinkler for disaster prevention (step S14). Further, whether or not the disaster prevention sprinkler has been restored can be confirmed by receiving a signal from the disaster prevention sprinkler that the sprinkler head is attached and that the setting is completed from the disaster prevention sprinkler.

In the event that the operator forgets to operate the release switch, even if a fire occurs, the valve will open due to the detection of the temperature sensor, so water must be sprayed from the sprinkler for disaster prevention and must be extinguished. You can In addition, it is preferable that the valve described above is provided with an operation handle that can be opened and closed manually. Further, in addition to the temperature sensor described above, a smoke detection sensor that detects smoke from a fire may be used. However, the operation of the smoke detection sensor is
Used when opening and closing the valve with a switch after the sprinkler is activated. Specifically, by detecting smoke after sprinkler sprinkling water, it is detected whether the fire is extinguished or whether the fire has reignited after extinguishing and the signal from the switch is received by the control means. It is preferably used to determine whether or not. In addition, although the above-described embodiment has been described with reference to an example applied to a house, the present invention is not limited to this and can be applied to an office building, a condominium, a department store, or the like.

In this embodiment, tap water is used as the water supply to the water supply system installed in the house, but not limited to tap water, purified water or purified water is used as the water supply. It can also be used.
