It is arranged as something to do.

Sensor with test function (hereinafter referred to as sensor)
Reference numeral 10 denotes a fire detector such as a heat detector or a smoke detector to which a test function is added, and a plurality of fire detectors are installed in, for example, a room of each dwelling unit. A doorphone with a remote test function (hereinafter referred to as a doorphone) 12 is a doorphone to which a remote test function is added, which is installed outside each dwelling unit (outside the door) and has a sensor 1
It is connected to 0 and its operation signal is input and broadcasted as it is, and a tester is attached as described later, which functions as a repeater when testing the sensor 10 and outputs a test signal. The GP type third class receiver (hereinafter, referred to as a fire receiver) 14 is one type of fire receiver, and displays a fire or generates a fire alarm based on input of a detector operation signal, a test signal, and the like. It is assumed that the fire receiver 14 is built in (or is also used for) an intercom, and has an intern function. The relay 16 for a sensor intervenes between the fire receiver 14 and the living room receiver 24 and functions as an interface when transmitting and receiving signals between the two.

The pre-operation SP dedicated repeater 18 is
When a sensor operation signal is input from the intercom 12 through the doorphone 12, the signal is immediately transmitted to the fire receiver 14 and the living room receiver 24, respectively, and when a test signal is input from the intercom 12, the signal is output to the fire receiver 14. The pre-operation SP dedicated relay 18 receives the valve opening control signal and the valve closing control signal from the living building receiver 24 and outputs them to the flowing water detecting device unit 20, or a sensor as described later. 10
It has a function to detect abnormalities.

The flowing water detecting device unit 20 is a so-called valve rotation of a pre-operation valve MV provided in a water supply pipe to which a plurality of closed-type sprinkler heads S are connected. A control valve V1 arranged on the next side;
A paddle-type running water detection switch FD disposed on the secondary side of the pre-actuation valve MV, a bypass flow path SR having a check valve SV for bypassing these, a secondary pressure drop detection pressure switch PS, And a remote start valve PV for enabling the valve MV to be opened by a decompression opening method.
The control valve V1 is a valve that can manually close the water supply pipe, but is provided with a limit switch L1 that detects the open state by the position of the handle and the like.
The remote start valve PV is provided with a limit switch L2 that detects an open state by a motor position or the like that does not show the open state in detail, separately from the input of the open / close control signal. In addition, it goes without saying that fire extinguishing water is supplied to such a pre-actuation valve MV from a water storage tank (not shown in detail) by a pressurized water supply device such as a pump P.

The operation of the pre-actuation valve MV having such valve rotation will be briefly described.
The primary pressure and the secondary pressure are maintained at the same pressure by the bypass flow path SR, and the remote start valve PV is always closed, so that the piston chamber (not shown) of the pre-actuation valve MV is also maintained at the same pressure. Have been. In the event of a fire, the sensor 10 is first activated and the remote activation valve PV is opened accordingly. By opening the remote start valve PV, the piston chamber (not shown) of the pre-operation valve MV is depressurized by drainage, and the valve body (not shown) of the pre-operation valve MV is opened. And the closed type sprinkler head S is opened by the heat of the fire,
Fire extinguishing water starts to be discharged from the sprinkler head S via the pre-actuation valve MV. This water discharge causes water to flow in the water supply pipe, and the water flow detection switch FD operates to output a water flow signal. When only the detector 10 is operated as a non-fire condition, the pre-actuation valve MV is opened as in the case of the fire described above, but since the sprinkler head S is closed, no water is discharged and water loss is prevented. Is done. When only the sprinkler head S operates as a non-fire event, the pre-actuation valve MV
Although the residual water is temporarily discharged from the secondary side water supply pipe of the above, since the pre-actuation valve MV is closed, only a small amount of fire extinguishing water is continuously discharged through the bypass passage SR, and large No water damage. Here, a bypass flow path SR is provided around the valve of the pre-operation valve MV to enable the secondary side to be filled with water in the same manner as the primary side, and a so-called wet pre-operation system is used. The road SR may be deleted and a pre-operation type in which the secondary side conventionally used is a dry type may be used. Further, it is needless to say that the fire extinguishing water supplied to the secondary side may be regulated in pressure, and the pre-actuating valve MV may be of a pressurized and opened type instead of a reduced pressure and open type.

The terminal repeater 22 receives the running water signal, the control valve opening signal, the test signal, and the secondary pressure drop signal of the running water detecting device unit 20 and receives a living building receiver (R-type receiver). 24. The terminal repeater 22 is installed for each floor, and the above-mentioned running water detection device unit 2

(S4) The living room receiver 24 is also operated under a certain condition (for example, on condition that the test or inspection is not being performed).
Then, a valve opening control signal for opening the remote start valve PV is transmitted to the pre-operation SP dedicated relay 18, and the pre-operation SP dedicated relay 18 transmits a valve opening control signal for opening the electric remote start valve PV. Is output to the flowing water detection device unit 20. When receiving the valve opening control signal, the flowing water detection device unit 20 opens the remote start valve PV. Here, the valve opening control signal is an operation current application in the opening direction.
In conjunction with the opening of the remote start valve PV, the pre-actuation valve MV is also opened, and the primary side and the secondary side of the water supply pipe of the sprinkler fire extinguishing equipment become conductive.

(S5) When the running water detecting device unit 20 opens the remote start valve PV, the contact of the limit water L2 for detecting the opening is closed, and the valve indicating that the remote start valve PV is opened is opened. The signal is output, and the pre-operation SP dedicated repeater 18 transmits the signal to the living room receiver 24 by inputting the valve open signal. When receiving the valve open signal, the living room receiver 24 displays that the remote start valve PV has been opened and generates an alarm (the open signal in the flowcharts in FIGS. 2 to 7 indicates the valve open signal). ).

(S6) On the other hand, the fire receiver 14 continuously inputs a sensor operation signal for a predetermined time, for example, 2 minutes from the alarm of the sensor as a so-called accumulation operation, or a fire occurs when a person is present in the dwelling unit. When it is determined that the fire receiver 14 has been operated, a fire is displayed and an alarm is generated. Then, the fire receiver 14 transmits a fire signal to the dwelling receiver 24 via the sensor repeater 16 (the fire repeater in the flowcharts in FIGS. 2 to 7 indicates the sensor repeater 16). ing).

(S7) Upon receiving the fire signal, the living building receiver 24 displays a fire and issues an alarm.

An alarm signal is transmitted to. Upon receiving the alarm signal via the sensor repeater 16, the fire receiver 14 of the dwelling unit on the fire floor and the floor immediately above the fire floor displays a fire and generates an alarm.

(S9) When a fire occurs and the sprinkler head S is melted and opened, the pre-actuation valve MV is already opened at that time, and the primary side and the secondary side are brought into conduction. Therefore, water is discharged from the sprinkler head S, and fire extinguishing is started. By this water discharge, the paddle type running water detection switch FD of the running water detection device unit 20 is operated to output a running water signal, and the terminal repeater 22 inputs the running water signal and outputs it to the living room receiver 24 (FIGS. 2 to 3). The operation of the flowing water detection device in the flowchart in FIG. 7 indicates a flowing water signal output by the operation of the flowing water detection switch FD).

(S10) When receiving the running water signal, the living building receiver 24 displays the sprinkler head S open and issues an alarm.
