Such a system also deserves to be improved to respond as quickly as possible to an incident, such as an accidental fire affecting the premises, a water leak or the like.

An aim of the present invention is to provide a device for securing a premises, such as a home, in particular a detached house, apartment, craftsman's workshop or the like, which is simple to install on a water supply pipe. equipping the premises, this device not only makes it possible to alert a user of the premises as quickly as possible after detection of an incident, particularly fire or water leak, but also to act very quickly to stop the incident, before it spreads, for example by rapidly increasing the temperature of the place, creating an effect of panic, burns, poisoning caused by the inhalation of vapors released by burning elements, or even sometimes the death of the people present, or by weakening the structure of the premises.

Another aim of the present invention is to propose a method of implementing such a device which is simple, rapid and effective to thwart the incident as quickly as possible, even before the arrival of emergency services, firefighters. , or even before emergency services are contacted.

Another aim of the present invention is to provide security for the premises, housing or other before human intervention. This way, emergency services can be contacted without panic.

The present invention fits into this context and proposes a security device as well as a method for securing a premises which generally comprises a plurality of steps.

More particularly, the security device of the present invention is a device for securing a premises. The security device comprises a water supply pipe in fluid relationship with a water pipe which extends between a water inlet equipping the water supply pipe and a water outlet.

According to the present invention, the water pipe is in fluid relationship with a extinguishing agent pipe which extends between a mixer and a reserve of an extinguishing agent. The extinguishing agent is preferably a foaming agent suitable for daily interventions by firefighters, such as small hydrocarbon fires, car fires, agricultural machinery, apartments, buildings or the like.

The security device advantageously comprises at least one of the following technical characteristics, taken alone or in combination:

The power circuit breaker is preferably a main differential circuit breaker which supplies secondary power circuit breakers, which in turn individually supply the equipment connected to the sockets and cable outlets in order to secure the premises, or an individual power circuit breaker a water heater as well as an associated means of communication confirming and notifying their trigger opening, such as feedback, equipping the premises.

- the home automation center is equipped with means of actuating a solenoid valve fitted to the water pipe supplying the premises.

- the security device comprises an electronic card linked to at least one temperature sensor and the home automation system.

Even more particularly, the present invention proposes a method for implementing such a security device.

The method includes a first step which consists of measuring a value of a physical quantity using a sensor. The sensor is advantageously a flow sensor fitted to a water pipe in the premises. The water pipe is for example a pipe which is in fluid relationship with the water supply pipe of the premises and which is intended to deliver water into the premises to stop a fire affecting the latter. The water pipe is, for example, still a drain pipe equipping a water heater housed in the room. Note that the number of pipes and diffusers depends on the intrinsic capacity of a regulator, pressure reducer of the water network in terms of flow rate and a minimum section of the water supply line. This line or pipeline must be identified and dedicated solely to this use.

The method comprises a step of comparing the measured value of the measured physical quantity with a set value of the physical quantity. According to a preferred embodiment, if the measured value is greater than the set value, it is deduced that an incident has occurred. The comparison step is for example carried out by calculation means, comprising for example an integrated intrinsic algorithm, which equip an autonomous electronic card powered by a battery. The variation in the original physical quantity therefore makes it possible to deduce that an incident has occurred. The comparison step is for example carried out by the electronic card constituting the local security device. The flow sensor is in fact a stand-alone connected flow alarm that can be used in a large number of areas, such as confirmation of recirculation in periods of frost and, in other circumstances described below.

The method comprises a first step of transmission via first means of communication equipping the electronic card with an incident indication via a wireless protocol to a home automation center equipping the home or premises.

The method comprises a second step of transmission via second intrinsic communication means equipping the home automation center with the incident indication to a relay antenna of a remote communication network.

The method comprises a third step of transmitting via the remote communication network the incident indication to one or more receiving terminals, such as a telephone or several mobile telephones, including the user or users of the local are in possession. These provisions are such that the users of the premises, whether owners and/or tenants, are informed in real time of the incident, and of the nature of it, fire, flooding in particular, and are able to act to prevent accidents in particular. adequate relief.

The method also includes a connected sound warning step during which the home automation center broadcasts a sound alert relating to the incident via at least one connected alarm siren fitted to the home or the premises, the alarm siren being capable of generating a sound alert of more than 90 decibels equipping the home or premises.

The method also includes a connected digital warning step, during which the home automation center activates the provision of various pictograms in relief, and with subtitles written in Braille which are intended to indicate the incident in progress to a user partially sighted or blind.

The method also includes a connected visual warning step during which one or more visual signs and anti-panic lighting in the middle of the night, and for example while the occupants are sleeping, are activated to inform the user of the incident. in progress and provide him with safety instructions.

The method also includes a step of isolating an electrical power circuit equipping the premises from an electrical power failure instruction transmitted by a trigger connected to the main power supply of the power circuit. We understand that a power circuit control panel is equipped with said trigger which is connected by non-wired network to the home automation center. When the home automation center receives the incident indication, the latter is able to immediately transmit to the trigger an instruction to cut off the electrical supply to the power circuit. These arrangements are such that as soon as the home automation center receives an indication of a fire type incident, the home automation center is able to instantly disconnect the electrical power circuit so that water is delivered to extinguish the fire. therefore possible without hazards.

This same connected trigger is also mechanically connected to an auxiliary contact module connected to the connected independent electronic card which notifies the user of the incident, via the home automation center and the relay antenna, such as the opening of the circuit breaker. This connected auxiliary contact also has another role, namely, during the absence of the user, if the circuit breaker opens, either by overcurrent or by insulation fault coming from one of the electrical equipment in the premises, the The user is immediately informed, notified and is not surprised by the incident and the user knows its duration, that is to say the time elapsed between the incident and his return to the premises. Furthermore, for a room equipped with a gas pipe, a solenoid valve could be installed upstream in order to isolate and cut off this risky supply.

The method also comprises a step of mixing a fire extinguishing agent, emulsifier such as an emulsifier, in particular foaming and/or wetting, of the type used by firefighters, inside the water pipe intended to stop a fire affecting the premises. This effect is achieved from a mixer, a mixer comprising a Venturi type device which equips the water pipe, this device, which only operates in one direction of liquid circulation, being itself in fluidic relationship with a extinguishing agent pipe which houses a return member associated with a ball. The arrangement of the mixer is such that when water circulates inside the water pipe, a vacuum is generated inside the extinguishing agent pipe, such that the return member is compressed by the movement of the ball. Such a movement frees a passage that the ball was obstructing, which allows circulation of the extinguishing agent inside the pipe of external agent which mixes inside the water pipe. As soon as the circulation inside the water pipe is stopped, the return member pushes the ball against the passage which prevents the circulation of extinguishing agent towards the water pipe. So when no water circulation occurs inside the water pipe, no mixture of water and extinguishing agent is possible. This Venturi mixer/mixer due to its internal design only works in one direction. An arrow engraved on the exterior of the body indicates the direction of circulation and installation. In the event of a loss of pressure inside the water supply pipe, no vacuum is generated so it is impossible for the extinguishing agent to enter the pipes of other devices. On standby or outside of an incident, the extinguishing agent pipe is blocked and the water pipe cannot be emptied. Any maneuver upstream of the mixer has no influence on the movement of the ball held against the passage.

Here we recall the operation of a Venturi type device: water enters and penetrates this device through the largest section of the cone. The fluid therefore moves towards the smaller section, which increases its speed and reduces its static pressure (pressure exerted on the surface of the wall). At the narrowest section of the cone, the fluid speed is at a maximum and its static pressure at a minimum. Just beyond this restriction of the cone is a small chamber or chimney whose section is much greater than the inlet section of the cone. This sudden change of section is such that it creates depression. This depression applies to each square millimeter of its surface. In this same chamber, there is a ball resting against its seat with the help of a spring. The speed is generated solely by the flow from a section restriction, which in turn generates a depression which also applies to this ball. When the flow and/or the speed and/or the depression is sufficient, that is to say a depression greater than the stress pressure of the spring occurs, the ball compresses the spring sufficiently to make this ball take off from its seat and thus free the orifice, that is to say the passage blocked by this ball. This depression will propagate in the pipe which blocked this passage, pipe connected to the tank where the foam concentrate is located. A vent on the tank allows it to be permanently at atmospheric pressure. The foam concentrate is therefore sucked in, and allowed to circulate to knead, mix with the water in the pipe then head towards the outlet of the Venturi type organ. As the flow decreases, then stops, the speed decreases, then stops; depression decreases, then stops; the suction of the extinguishing agent decreases, then stops; this same depression exerted on the surface of the ball decreases, then stops; the spring decompresses and returns to reposition itself and hold this ball against its seat; blocking and preventing the circulation of the extinguishing agent towards the water pipe of the circuit. In service and out of flow, this ball is pressed against its seat partly by the pressure of the fluid but also by the pressure exerted by the spring. Thus, without sufficient flow, without sufficient speed, without sufficient water circulation, circulation does not occur inside this water pipe located downstream or in a Venturi type device, unidirectional, no mixing of water and extinguishing agent is not possible. On standby or outside of an incident, the pipe being blocked, the water pipe cannot empty in the event of a loss of pressure in the water network.

The installation of a tap, connection with a quarter-turn valve on this water pipe placed upstream of the Venturi type device and downstream of the autonomous connected flow sensor allows a monthly or quarterly test, without risk of water mixing /emulsifier, the proper functioning of actions such as safety and signaling. Depending on the characteristics of the water network, approximately 20 centiliters are sufficient for this test. This is drinking water which can therefore be consumed.

According to a first variant, the detection of the incident is carried out using an autonomous and remote connected temperature sensor because it is connected to a telephone type cable which allows it to be effective anywhere. This temperature sensor is discreet due to its small size, of the order of a small coin, which also offers a wide range of temperature choices both very suitable for premises/housing in places with moderate temperatures as well as in places where the temperature is often normally high, such as professional restaurant kitchens with significant steam production, workshops with significant production of smoke and/or dust, laundries/dry cleaners and others. It can be installed in an environment close to a heat source, the origin of a possible fire and thus transmit an abnormally high temperature in order to act as quickly as possible. This autonomous connected temperature sensor is therefore not disturbed by smoke, dust or vapors.

According to a second variant, the water pipe is equipped with a thermal fuse, such as a sprinkler type diffuser which is for example placed on the ceiling of the room, to detect a fire inside the room. The thermal fuse comprises a thermal bulb whose melting and/or rupture temperature is between 58°C and 70°C. Depending on the location to be protected, a cover can be installed for aesthetic or discreet reasons on the thermal fuse. For example, it is of plant origin and self-disconnects as soon as the temperature reaches 53°C or 60°C depending on the fuse installed. In other words, the thermal bulb breaks when the thermal bulb reaches its rupture threshold, which releases the shutter which causes a dispersion of water and extinguishing agent in the room.

The method also includes a step of opening a solenoid valve fitted to the water pipe, the solenoid valve being movable between a closed position in which the solenoid valve prohibits the circulation of water inside the pipe, and an open position in which the solenoid valve allows water circulation inside the water pipe to the thermal fuse. The solenoid valve can preferably be controlled remotely via the home automation center. This solenoid valve is located downstream of the Venturi type organ mentioned above. Downstream of this solenoid valve, there is a diffuser (without bulb/thermal fuse) allowing watering, spraying of water and emulsifier. Depending on the location to be protected, a cover can be installed for aesthetic or discreet reasons on this diffuser. It is also of plant origin and self-decomposes on contact with water pressure.

The water pipe is for example connected to a reserve comprising two compartments, including a first compartment housing water and a second compartment housing antifreeze and/or vehicle coolant. The first compartment is in fluid relationship with the water pipe. The second compartment is connected to the water pipe which is provided with a diffuser, a thermal fuse housed at the top of the chimney flue. The compartments are separated from each other by a partial partition and an air buffer. Breaking the thermal fuse releases the shutter which will release the circuit including the antifreeze. The pressure exerted by the water inside the first compartment pushes, expels and evacuates the air buffer, so that the antifreeze liquid flows inside the water pipe towards the diffuser. The circuit self-bleeds, creates a flow rate, a speed and a flow which consequently activates the Venturi type organ by suction of extinguishing agent located in the small tank. The autonomous connected flow sensor immediately informs the home automation center which in turn activates the various signals (audible, visual, digital, SMS), or even activates such as a closing electromagnet, and/or the shutter/valve. combustion air inlet.

Also, for regions or countries where outdoor temperatures are extreme in winter, the chimney flue can be equipped with a connected temperature sensor which is in no way influenced by extreme cold. The temperature sensor is connected to an independent electronic card which is offset several meters, therefore easily accessible, via a telephone type cable, in order to be able to replace a battery without having to access the roof of the premises with a risk of falling. This independent and autonomous electronic card which includes both an intrinsic algorithm and a wireless communication protocol which communicates permanently with the home automation system. The electronic card indicates, as soon as a temperature threshold is crossed, for example during an abnormally high smoke temperature, typically greater than 120°C, 160°C or 200°C, or even more, signifying a fire in the chimney flue not visible from inside the premises or accommodation, or even during the user's sleep or absence and risking the spread of the fire to the roof. The water pipe is for example connected to a reserve comprising an anti-freeze liquid, vehicle coolant for example. The anti-freeze liquid is mixed with the water circulating inside the water pipe as soon as the home automation control unit commands the opening of the solenoid valve to move towards the prototype diffuser, described below, however without thermal bulb and quickly extinguish the start of a fire in the chimney flue, quickly in a few seconds, knowing that there is no draft since the combustion air damper/valve is closed and the watering is in progress. The independent and autonomous connected flow sensor confirms the opening of the solenoid valve with a notification such as “chimney flue watering in progress”. Depending on the network of the receiving terminal, it is very likely that said chimney flue fire notification will be received by the user even though the fire has already been extinguished. It is then possible to view on the receiving terminal the status of the connected thermal contact which returns to its normal threshold, excluding alert, and normal temperature.

This independent and autonomous connected temperature sensor which is remote can therefore easily be installed in any place where access is difficult or even dangerous, for example close to controlled mechanical ventilation installed under a roof, a storage room, a frame or others.

The method also includes a step of setting in motion a linkage equipped with a shutter or valve for closing a combustion air inlet inside the chimney, the shutter being actuated by the linkage provided with an electric actuator and being movable between a closed position in which the shutter prevents a circulation of fresh air through the fresh air inlet of the chimney, and an open position in which the shutter allows a circulation of fresh air through through the fresh air inlet from the chimney. The actuator can preferably be controlled remotely via the home automation center.

These arrangements are such that when the thermal bulb breaks under the effect of an incident such as a fire in the premises or a chimney flue fire, the water under pressure at approximately 2.5 bars or more at the The inside of the water pipe begins to circulate to be evacuated and directed inside the flue.

Note that the thermal fuse includes an enclosure which houses the thermal bulb and a grid. The thermal bulb is housed inside an upper portion of the enclosure which is delimited from a lower portion via the grid. The grid is designed to accommodate a shutter as well as the thermal fuse which holds it in place and which obstructs a passage as long as the thermal bulb is not broken. As soon as the latter breaks, these elements fall by gravity and are pushed by the pressure of the water inside the enclosure to the grid. Consecutively, the antifreeze and/or vehicle coolant and/or water flows inside the enclosure to an evacuation to allow watering and/or diffusion on an internal wall of the ignited smoke pipe and thus extinguish the fire in a few seconds.

On the , a room 1 is equipped with a water supply pipe 2 which is intended to supply water to the room 1. Typically, a water pressure prevailing inside the water supply pipe 2 is greater at 2 bars. The room 1 is also equipped with a smoke evacuation conduit 3 which equips a heating installation 4. The heating installation 4 is indifferently a fireplace, an insert, a stove, a boiler or any other installation designed to burn fuel to heat room 1.

The premises 1 is advantageously provided with a security device 5 for the premises 1. The security device 5 comprises a water pipe 6 which extends between a water inlet 6a equipping the water supply pipe 2 and a water evacuation 6b equipping the smoke evacuation conduit 3 and more particularly a high point 3a of the smoke evacuation conduit 3. It is understood that a high point 3a of the smoke evacuation conduit 3 is a point culmination of the latter.

The water pipe 6 is provided with a mixer 7 which is in fluidic relation with a extinguishing agent pipe 8 which extends between the mixer 7 and a reserve 9 permanently at atmospheric pressure which contains an extinguishing agent 9a . The mixer 7 is able to authorize or prohibit circulation of the extinguishing agent 9a inside the extinguishing agent pipe 8. More particularly, the mixer 7 is movable between an open position in which the mixer 7 authorizes prohibit circulation of the extinguishing agent 9a inside the extinguishing agent pipe 8 via a ball 54 to mix with the water present inside the water pipe 6 with a view to being evacuated inside the smoke evacuation conduit 3 via the water evacuation 6b, and a closed position in which the mixer 7 prohibits such circulation.

The security device 5 also includes an electronic card 10 which is connected with a telephone type cable 10a with a temperature sensor 11 housed inside the smoke evacuation duct 3 to measure a smoke temperature T1. The electronic card 10 is provided with means 12 for comparing the smoke temperature T1 measured with a threshold temperature T2. If the smoke temperature T1 exceeds the threshold temperature T1, communication means 13 fitted to the electronic card 10 communicate remotely with a home automation unit 14 which is capable of remotely opening a solenoid valve 15 fitted to the water pipe 6. L The solenoid valve 15 is placed on the water pipe 6 downstream of the mixer 7, that is to say between the mixer 7 and the water outlet 6b. In this assembly, it is the same diffuser 31, as that illustrated on the but not equipped with thermal bulb 31a. The opening of the solenoid valve 15 causes a circulation of water inside the water pipe 6 so that a depression appears in the mixer 7. The mixer 7, described below on the , advantageously comprises a Venturi type device, such as a pressure-producing member with conical internals which, by its design, can only operate in one direction of circulation 16, that going from the mixer 7 towards the water discharge 6b, and in fact creates suction only in the event of circulation of water in the water pipe 6. This results in a mixture of the extinguishing agent 9a and the water inside the water pipe 6, this mixture circulating inside the latter until the water drain 6b, to extinguish the fire.

The security device 5 comprises a flow sensor 33 which is remotely connected to the home automation unit 14 equipping the water pipe 6. The flow sensor 33 is able to detect and notify a circulation of water inside of the water pipe 6, such water circulation being caused by the opening of the solenoid valve 15.

The home automation center 14 is equipped with means 17 of transmitting a first piece of information 17a relating to an occurrence of an incident to a receiver 18 of which the user is in possession. The receiver 18 is for example a mobile telephone connected to the home automation center 14 via a telephone relay antenna.

The home automation center 14 is equipped with information means 19 which are capable of transmitting second information 19a of the sound, digital, light or similar type to a location 20 distant from the smoke evacuation conduit 3, such as a bedroom, a living room or the like.

The home automation unit 14 is also equipped with means 21 for actuating a motor member 22 capable of moving an operating member 23 into the closing position of a combustion air intake flap 24 inside the heating installation 4. It is understood that the intake flap 24 is movable between a closed position in which the intake flap 24 allows an entry of air inside the heating installation 4 and a position closure in which the intake flap 24 prohibits such an entry of air.

The home automation unit 14 is also equipped with actuation means 44 on the solenoid valve 15 causing a flow rate, a speed and therefore a depression in the mixer 7. Thus, the flow rate inside the water pipe 6 is confirmed , and notified to the user by the flow sensor 33.

These arrangements are such that the fire inside the smoke evacuation duct 3 is quickly extinguished from the inlet of water and the extinguishing agent 9a inside the smoke evacuation duct 3 via the water drain 6a and from the operation of the inlet flap 24.

These provisions are also such that the user is quickly warned of the occurrence of the fire from the implementation of the means of transmission 17 and the means of information 19.

On the , a room 1 is equipped with a water supply pipe 2 which is intended to supply water to the room 1. Typically, a water pressure prevailing inside the water supply pipe 2 is greater at 2 bars. The room 1 is also equipped with a smoke evacuation conduit 3 which equips a heating installation 4. The heating installation 4 is indifferently a fireplace, an insert, a stove, a boiler or any other installation designed to burn fuel to heat room 1.

The premises 1 is advantageously provided with a security device 5 for the premises 1. The security device 5 comprises a water pipe 6 which extends between a water inlet 6a equipping the water supply pipe 2 and a water evacuation 6b equipping the smoke evacuation conduit 3 and more particularly a high point 3a of the smoke evacuation conduit 3. It is understood that a high point 3a of the smoke evacuation conduit 3 is a point culmination of the latter.

The water pipe 6 is provided with a mixer 7 which is in fluidic relation with a pipe of extinguishing agent 8 which extends between the mixer 7 and a reserve 9 of an extinguishing agent 9a. The mixer 7 is able to authorize or prohibit circulation of the extinguishing agent 9a inside the extinguishing agent pipe 8. More particularly, the mixer 7 is movable between an open position in which the mixer 7 authorizes prohibit circulation of the extinguishing agent 9a inside the extinguishing agent pipe 8 to mix with the water present inside the water pipe 6 with a view to being evacuated to the interior of the smoke evacuation conduit 3 via the water evacuation 6b, and a closed position in which the mixer 7 prohibits such circulation. Note that the extinguishing agent pipe 8 is equipped with a ball 54 to prevent the admission of water from the water pipe 6 into the reserve 9 which, via a vent, is permanently at atmospheric pressure .

The water pipe 6 is connected to a tank 100 comprising two compartments, 101, 102 including a first compartment 101 housing water and a second compartment 102 housing antifreeze and/or vehicle coolant. The first compartment 101 is in fluid relationship with the water pipe 6. The second compartment 102 is in relation with the water pipe 6 which is provided with a diffuser 31, such as a thermal fuse housed at the top of the conduit chimney 3. The compartments 101, 102 are separated from each other by a partial partition 103 as well as an air buffer 104. As illustrated below, the rupture of a thermal fuse of the diffuser 31 releases a shutter which will release the water pipe 6 including the antifreeze. The pressure exerted by the water inside the first compartment 101 pushes, expels, evacuates the air buffer 104, such that the antifreeze liquid flows inside the water pipe 6 towards the diffuser 31. The circuit self-purges, creates a flow rate, a speed and a flow which consequently activates the mixer 7 by suction of extinguishing agent 9a located in the reserve 9. The flow sensor 33 connected autonomously, immediately informs the home automation unit 14 which in turn activates the various signals (audible, visual, digital, SMS), or even activates such as a closing electromagnet, and/or the combustion air inlet shutter/valve.

The security device 5 comprises a flow sensor 33 which is linked to the home automation unit 14 equipping the water pipe 6.

These arrangements are such that the fire inside the smoke evacuation duct 3 is quickly extinguished from the inlet of water and the extinguishing agent 9a inside the smoke evacuation duct 3 via the water drain 6a and from the operation of the inlet flap 24.

These provisions are also such that the user is quickly warned of the occurrence of the fire from the implementation of the means of transmission 17 and the means of information 19.

The premises 1 is advantageously provided with a security device 5 for the premises 1. The security device 5 comprises a water pipe 6 which extends between a water inlet 6a equipping the water supply pipe 2 and a water drain 6b equipping a ceiling 30. The water drain 6b is equipped with a diffuser 31 which is capable of diffusing water after opening the solenoid valve 15 when a fire appears in the room 1 The diffuser 31 is for example provided with a cover 32 made in particular from a plant material and which is likely to be of varied colors.

On the , the mixer 7 comprises a Venturi type device 50 which equips the water pipe 6. The Venturi type device 50 only operates in one direction of circulation of liquid 51. The Venturi type device 50 is itself in relation fluidic with the extinguishing agent pipe 8 which is in fluidic communication with a chamber 52 housing a return member 53 associated with a ball 54. The arrangement of the mixer 7 is such that when water circulates inside the water pipe 6, a depression is generated inside the chamber 52 and subsequently the extinguishing agent pipe 8, such that the return member 53 is compressed by the movement of the ball 54. Such a movement frees a passage 55 that the ball was obstructing, which allows circulation of the extinguishing agent 9a inside the pipe of external agent 8 which mixes inside the water pipe. As soon as the circulation inside the water pipe 6 is stopped, the depression is stopped, disappears, the return member 53 pushes the ball 54 against the passage 55 which prevents circulation of extinguishing agent 9a towards the water pipe 6. Furthermore, when no circulation of water occurs inside the water pipe 6, no mixture of water and extinguishing agent is possible. The mixer 7 only operates advantageously in the direction of liquid circulation 51. In the event of a loss of pressure inside the water pipe 6, the line downstream of the mixer 7 being obstructed either by the thermal bulb 31a of the thermal diffuser or by the solenoid valve 15 no flow, no depression is therefore generated in the chamber 52 therefore it is impossible for the extinguishing agent 9a to be able to enter the chamber 52, and consecutively in the water pipe or in network conduits.

On the , the diffuser 31 includes an enclosure 60 which houses the thermal bulb 31a. The thermal bulb 31a is interposed between a shutter 61 and a grid 62. When the temperature is high, the thermal bulb 31a breaks, which causes the shutter 61 of the water pipe 6 to fall onto the grid 62 which retains it, while allowing the water and the extinguishing agent 9a to flow through orifices 63 which equip the diffuser 31. Preferably, the orifices 63 are provided in a direction forming an angle A with the normal which is of the order of 15°, and which depends on the distance from the cap of the smoke duct as well as the diameter of the duct. Note that a screw 64 is tightened to a determined torque, and passes through a lower wall 65 of the diffuser 31 in order to maintain the thermal bulb 31a resting against the shutter 61 obstructing the fluid passage of the pipe 6.
