Description

Title of the invention: Device for securing a premises and method for implementing such a device

[0001] The invention relates to a device for securing a premises. Its purpose is such a device. It also relates to a method of implementing such a device.

[0002] Document FR 3050119 describes a device for external detection of a movement of water or a leak inside a supply pipe. The device comprises a removable fixing around the supply pipe, a sensor with a value of a physical quantity representative of a movement of water in the supply pipe, a detector of the triggering of a sprinkler or a fire valve configured to detect the triggering according to the evolution of the sensed value and a transmitter of a signal representative of the sensed value when the triggering is signaled by the detector.

[0003] Such a device deserves to be improved to optimize the detection of an incident of any nature, in particular a fire or water leak, likely to affect a premises, such as a dwelling, in particular an individual house, an apartment, individual garage, craftsman's workshop or similar.

[0004] Such a device 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.

[0005] Such a device deserves to be improved to respond as quickly as possible to a natural event, such as an earthquake, in order to avoid secondary accidents, asphyxiation, fire, explosion or other.

[0006] An aim of the present invention is to propose a device for securing a premises, such as a dwelling, in particular a single-family house, apartment, craftsman's workshop or the like, which is simple to install on a pipe. water supply adapted to the pressure of the network of an individual 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, fire or water leak in particular, 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 of the respiratory tract caused by the inhalation of vapors released by burning elements, or even sometimes the death of people feelings, the psychological trauma of survivors or witnesses, without forgetting the impact of mechanical resistance, the weakening of the structure of the premises. During combustion in a fireplace hearth, fire, the infrared radiation generated by the flames combines with the vapors of burned particles, carbon-rich burned gases and forms soot during incomplete combustion. This incomplete combustion, producing thick and toxic smoke because it is loaded with soot, comes from a lack of oxygen in relation to the carbon particles contained in the fuel. As a result, this incomplete combustion also forms carbon monoxide which is invisible and very toxic.

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 depending on the case.

Another aim of the present invention is to provide security for the premises, housing or other before human intervention. This way, stress is kept at a low level and help can be contacted without panic.

[0009] Another aim is to allow any people with reduced mobility to be able to evacuate the place as a precautionary principle.

[0010] Another goal is to make it possible to alert a user in the event of an earthquake.

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.

[0012] 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. The water pipe is in fluid relationship with a extinguishing agent pipe which extends between a mixer and a reserve of an extinguishing agent.

According to the present invention, the mixer comprises a Venturi type device.

[0014] 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.

[0022] - the home automation center is equipped with means for triggering an individual power circuit breaker, a position transmitter module connected to a circuit breaker or a main power differential circuit breaker supplying the premises. The power circuit breaker is preferably a main differential circuit breaker which supplies secondary power circuit breakers or fuses, which in turn individually supply the various equipment connected to the sockets and/or via connectors on cable outlets in order to secure the premises. , or an individual power circuit breaker for a water heater as well as an associated means of communication confirming and notifying their tripping opening, such as feedback, equipping the premises.

[0023] - the home automation center is equipped with means for triggering an individual power circuit breaker of a connected auxiliary module and/or a main power differential circuit breaker of a connected auxiliary module or connected position transmitter supplying the local.

[0024] - the home automation center is equipped with means for actuating a solenoid valve fitted to the water pipe supplying the premises and/or an electronic valve fitted to the gas pipe supplying the premises,

[0025] - the security device comprises an electronic card linked to the home automation center,

[0026] - the electronic card is linked to at least one temperature sensor.

[0027] - the electronic card is linked to a seismic sensor.

[0028] - the seismic sensor comprises a transparent enclosure and an electrically insulating plate, the transparent enclosure housing a conductive ball, the electrically insulating plate comprising a calibrated hole capable of supporting the conductive ball, an- even concentric conductive rings and odd concentric conductive rings.

[0029] Even more particularly, the present invention proposes a method for implementing such a security device.

The method comprises a first step which consists of measuring a value of a physical quantity using a sensor. The sensor is advantageously a connected flow sensor fitted to a local water pipe. 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 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. It can be connected to an inverter as it does not have a power supply intrinsically rescued.

[0034] The method comprises a third step of transmitting the incident indication via the remote communication network to one or more receiving terminals, such as a telephone or several mobile telephones, including the user or the users of the premises 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.

[0035] The method also includes a connected sound warning step during which the home automation center activates a broadcast of a sound alert relating to the incident via at least one connected alarm siren equipping the home or premises, the alarm siren being able to generate a sound alert of more than 90 decibels equipping the home or premises.

[0036] The method also includes a connected sensory warning step allowing recognition of an event by touch, during which the home automation center activates the internal circuit of a box, specific support including an update provision of various selectable raised pictograms, and depending on the configuration of the location, additional information, instructions or other subtitles, written in Braille which are intended to indicate the incident in progress to a visually impaired or blind user.

[0037] The method also includes a connected visual warning step during which one or more visual signs and/or usual lighting acting as an anti-panic in the middle of the night, and for example while the occupants are sleeping, or else in the middle of the day for the hearing impaired or in a noisy environment, are activated to inform the user of the incident in progress and provide them with safety instructions.

[0038] 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 and mechanically linked to the circuit breaker of the main power supply of the power circuit. This trigger is an electromechanical element which acts following a simple impulse that it receives and which will immediately release its mechanism, which is connected to the circuit breaker to open it and therefore electrically isolate the power circuit that it supplies. Resetting the circuit breaker or differential circuit breaker can only be done after a return to the normal situation, and by manual action on this circuit breaker. We understand that a circuit control panel power 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 only. 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. Furthermore, for a room equipped with a gas pipe, a solenoid valve could be installed upstream in order to isolate it and cut off this risky supply.

[0039] This same connected trigger is also mechanically connected to an auxiliary module, connected to an independent connected 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 module or connected position transmitter 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 equipment electrical of the premises, the user is immediately informed, notified and is not surprised by the incident and the user knows the duration, that is to say the time elapsed between the incident and his return to the local.

[0040] The method also includes a step of mixing an emulsifying extinguishing agent, stored in an easily concealable tank of approximately 20 liters, depending on the number of diffusers, the surface area, the geometry and the layout of the room. . The foaming extinguishing agent, in particular foaming and/or wetting, is 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 pipe. water station. 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 in no way influences the movement of the ball held against the passage.

[0041] We recall a principle of the dynamics of liquid or gaseous fluids: in a pipe of constant section at constant flow rate the static pressure, dynamic pressure and kinetic energy are constant.

[0042] Thus, it was demonstrated by the physicist Venturi that a fluid circulating in a pipe, at the level where the section is reduced, the flow speed increases and causes a depression to appear. More precisely, we recall here the operation of a Venturi type device, which is a pressure-producing organ with conical internals which has been improved, optimized and adapted in many fields such as industry, agriculture and others. In general, it is an element machined and inserted in a pipe. Inside, there is a flow inlet on the main circuit, in our case a water circuit, its circulation section has a converging narrowing up to a calibrated section diameter allowing an optimal reduction in static pressure, an optimal increase in kinetic energy, an optimum flow speed in order to obtain depression, optimal suction. At the end of the calibrated shrinkage, a sudden change in section is carried out, an enlargement, caused by a cavity, a cylindrical chamber perpendicular to the direction of the fluid generates an expansion, inducing a depression, a suction. At its end, behind the ball acting as a non-return valve, there is a secondary pipe which is connected between this valve and the tank in order to suck up, in our case, the foam concentrate. This vacuumed emulsifier will mix with the water to move towards the divergent outlet of the Venturi type device. The water enters and penetrates this device through the largest section of the cone. The fluid moves towards and therefore converges towards the smaller calibrated section, which increases its flow speed and reduces its static pressure (pressure exerted on the surface of the wall). At the narrowest section of the cone, the fluid flow speed is then at a maximum and its static pressure at a minimum. Just after this restriction of the cone, where the section enlarges suddenly there is a small cylindrical chamber perpendicular to the main pipe. This sudden change of section is such that it creates, generates and amplifies relaxation and depression. This depression applies to each square millimeter of its surface and each cubic millimeter of the volume of this chamber. At the end of this same chamber, there is a ball resting against its seat with the help of a stainless spring. The flow speed is generated solely by the flow passing through a restriction of calibrated section, 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 into the secondary pipe which blocked this passage, a connected pipe plunging into the tank where the foam concentrate is located. A vent on the tank allows it to be permanently at atmospheric pressure preventing it from collapsing while its contents are being suctioned. The foam concentrate is therefore sucked in, and allowed to circulate to mix, mix with the water in the pipe and then head towards the outlet of the Venturi type device. As the flow decreases, then stops, the flow speed decreases, then stops; relaxation, depression decreases, then stops; the suction of the extinguishing agent decreases, then stops; this same depression, force 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 on the one hand by the pressure of the fluid but also by the pressure exerted by the spring. Thus, without sufficient flow, without sufficient flow speed, without sufficient water circulation, circulation does not occur inside this water pipe located downstream or in a Venturi type device, unidirectional, no mixing water and extinguishing agent is not possible. On standby or outside of an incident, the pipe being blocked, the extinguishing water pipe cannot be emptied in the event of a loss of pressure in the water network.

[0043] 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/emulsifier mixture, the correct functioning of the selected actions such as safety and signaling. Depending on the characteristics of the water network, approximately 20 centiliters are sufficient for this test. As this installation is on a drinking water network, it can therefore be consumed. [0044] According to a first variant, the detection of the incident is carried out using an autonomous connected temperature sensor with its remote electronics 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 few millimeters, which also offers a wide range of temperature choices as well as very suitable for premises/dwellings 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 such as a boiler room, laundry room, individual kitchen and other, workshops with production of welding fumes or engine exhaust thermal and/or sanding or cutting dust. 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 or affected by smoke, dust, volatile powders or vapors. Its design therefore makes it also suitable and effective for connected fire detection for DIY workshops, craftsmen, bars, homes and other premises even occasionally having this type of specific environment. There is a certain technology of fire sensor by optical detection called smoke detector based on the physical phenomenon of air opacity, compared in a dark room with multiple openings provided with deflectors preventing the penetration of light or radiation from the sun while by allowing ambient air to circulate between an emitting LED and an unaligned receiving photodiode reacting to UV or IR. However, this technology does not make it possible to differentiate and distinguish steam, cooking smoke, welding or other smoke generated by a fire. Optical detectors are therefore not suitable for all types of premises. A fire in a room causes its ambient temperature to increase, which will be identified and signaled by the connected temperature detector. It is therefore important to choose the right fire detection technology to act as quickly as possible and protect the premises, the people present and the neighborhood.

[0045] 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 is a thermal bulb with a melting and/or rupture temperature of between 58°C and 70°C. Depending on the area to be protected, a cover with a truncated conical or cylindrical or other geometric shape and a color similar to the ceiling can be installed for aesthetic or discretionary reasons on the diffuser. It is, for example, of plant origin and under the effect of high temperature will self-disconnect as soon as the temperature reaches dyed approximately 53°C or 60°C depending on the fuse installed. The mixture of this plant cover is adapted to the thermal fuse used. In other words, the thermal bulb breaks when it reaches its breaking point, which releases the shutter which causes a dispersion of water and extinguishing agent in the room.

[0046] 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 circulation of water inside of 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 is preferably 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 with a truncated conical or cylindrical geometric shape or hexagonal prism or other and in a color similar to the ceiling can be installed for aesthetic or discretionary reasons on this diffuser. It is also of plant origin and self-decomposes quickly upon contact with irrigation water.

[0047] 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 a 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 as well as an air buffer at network pressure. Breaking the thermal fuse releases the shutter which will release the circuit comprising the antifreeze pushed by the pressure of the air buffer. The pressure exerted by the water inside the first compartment pushes, pushes, in turn evacuates the air buffer, so that the antifreeze liquid flows inside the water pipe towards the Streamer. The circuit self-purges, creates a flow rate, a flow speed which therefore activates the Venturi type device 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 selected signals (audible, visual, digital, SMS), or even activates such as a closing electromagnet, and/or the shutter/valve. combustion air inlet from the fireplace.

[0048] Also, for regions or countries whose exterior 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 a 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 of the fireplace is closed and that 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 is received by the user when the fire has already been extinguished. It is then possible to view on the receiver terminal the status of the connected thermal transmitter which returns to its normal threshold, excluding alert, and normal temperature.

[0049] 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.

[0050] 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 or flap prevents circulation of fresh air through the fresh air inlet of the chimney, and an open position in which the shutter allows circulation of fresh air through the fresh air inlet from the chimney. The actuator is preferably controlled remotely by via the home automation center.

[0051] These arrangements are such that when the thermal bulb breaks under the effect of an incident such as a fire in the room or a chimney flue fire, the water under pressure at approximately 2.5 bars or further inside the pipe of the extinguishing circuit begins to circulate to be evacuated and directed inside the smoke duct.

[0052] 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.

[0064] [Fig. 11] represents a detailed view of the variant illustrated in Figure 10.

[0065] In Figure 1, 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 pipe d The water supply 2 is greater than 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.

[0066] 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. water 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 highlight 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 a 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 comprises 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 TL The electronic card 10 is provided with comparison means 12 of the smoke temperature Tl measured with a threshold temperature T2. If the smoke temperature Tl exceeds the threshold temperature Tl, communication means 13 fitted to the electronic card 10 communicate remotely with a home automation unit 14 which is able to remotely open 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 in Figure 7 but not equipped with a 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 in Figure 6, 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 evacuation 6b, and fact creates a suction only in the event of sufficient water circulation 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.

[0069] 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 to inside 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.

[0071] The home automation center 14 is equipped with information means 19 which are capable of transmitting second information 19a of the sound, digital, luminous or similar type to a location 20 distant from the smoke evacuation conduit 3, such as a bedroom, living room or the like.

[0072] The home automation center 14 is also equipped with means 21 for actuating a motor member 22 capable of moving a maneuvering member 23 into the closing position of a combustion air intake flap 24 to the interior of 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 the heating installation 4 and a closed position in which the intake flap 24 prevents such an entry of air.

[0073] The home automation center 14 is also equipped with actuation means 44 on the solenoid valve 15 causing a flow rate, a flow speed and therefore a depression, suction in the mixer 7. Thus, the flow inside the the water pipe 6 is confirmed, and notified to the user by the flow sensor 33.

[0074] These arrangements are such that the fire inside the smoke evacuation conduit 3 is quickly extinguished from the inlet of water and the extinguishing agent 9a inside the exhaust conduit. smoke evacuation 3 via the water evacuation 6a and from the operation of the intake flap 24.

[0075] These provisions are also such that the user is quickly informed of the occurrence of the fire from the implementation of the transmission means 17 and the information means 19.

[0076] In Figure 2, 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 pipe d The water supply 2 is greater than 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.

[0077] 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. water 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 highlight 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 only to the inside the smoke evacuation conduit 3 via the evacuation water 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 .

[0079] 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 a coolant of vehicle. 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 sufficient flow speed which consequently activates the mixer 7 by suction of extinguishing agent 9a located in the reserve 9. The flow sensor 33 connected autonomously, informs immediately 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 fireplace.

[0080] The security device 5 comprises a flow sensor 33 which is linked to the home automation unit 14 equipping the water pipe 6. The flow sensor 33 is capable of detecting and notifying a circulation of water to the interior of the water pipe 6, such water circulation being caused by the rupture of the thermal bulb 31a, release of the shutter 61 which are located in the diffuser 31.

[0082] The home automation center 14 is equipped with information means 19 which are capable of transmitting second information 19a of the sound, digital, luminous or similar type to a location 20 distant from the smoke evacuation conduit 3, such as a bedroom, living room or the like. [0083] The home automation unit 14 is also equipped with means 21 for actuating a motor member 22 capable of moving a maneuvering member 23 into the closing position of a combustion air intake flap 24 at the interior of the heating installation 4. It is understood that the intake flap is movable between a closed position in which the intake flap allows an entry of air inside the heating installation 4 and a closed position in which the intake flap 24 prohibits such air entry.

[0084] These arrangements are such that the fire inside the smoke evacuation conduit 3 is quickly extinguished from the inlet of water and the extinguishing agent 9a inside the smoke evacuation conduit. smoke evacuation 3 via the water evacuation 6a and from the operation of the intake flap 24.

[0085] These provisions are also such that the user is quickly informed of the occurrence of the fire from the implementation of the transmission means 17 and the information means 19.

[0086] In Figure 3, 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 pipe d The water supply 2 is greater than 2 bars.

[0087] 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. water 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 of 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.

The water pipe 6 is provided with a mixer 7 which is in fluid relationship 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 only to the inside the room 1 via the water drain 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 avoid admission of water coming from the water pipe 6 into the reserve 9 which, via a vent, is permanently at atmospheric pressure.

[0089] The security device 5 also comprises an electronic card 10 which is connected via a telephone type cable 10a with a temperature sensor 11 equipping the room 1 to measure a temperature of the room T' 1. The electronic card 10 is provided comparison means 12 of the temperature of the room T' 1 measured with a threshold temperature T2. If the temperature of the room T' 1 exceeds the threshold temperature T2, communication means 13 fitted to the electronic card 10 communicate remotely with a home automation unit 14 which is able to remotely open a solenoid valve 15 fitted to the water pipe 6 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. 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 in Figure 6 , 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 sufficient water circulation 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 6a, to extinguish the fire.

[0090] 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 to inside the water pipe 6, such water circulation being caused by the opening of the solenoid valve 15.

[0092] 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 in a distant location, such as a bedroom, a living room, office or similar.

[0093] The home automation center 14 is also equipped with means 44 for actuating the elec- trovalve 15 causing on the water pipe 6 a flow rate, a speed and therefore a depression in the mixer 7. Thus the flow rate is confirmed, and notified to the user by the flow sensor 33.

[0094] The home automation center 14 is also equipped with triggering means 25 of a main power differential circuit breaker 35 as well as a connected auxiliary module or connected position transmitter 35a supplying the room 1 which confirms and notifies the user the opening of the main power differential circuit breaker 35 via the home automation unit 14.

[0095] These arrangements are such that the fire inside the room 1 is quickly contained, or even extinguished, from the admission of water and the extinguishing agent 9a inside the room 1 by the intermediate water evacuation 6a.

[0096] These provisions are also such that the user is quickly informed of the occurrence of the fire from the implementation of the transmission means 17 and the information means 19.

[0097] In Figure 4, 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 pipe d The water supply 2 is greater than 2 bars.

[0098] 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. water 2 and a water drain 6b equipping a ceiling 30 of the room 1. The water drain 6b is equipped with a diffuser 31 which is capable of diffusing water when a fire appears in the room 1. The diffuser 31 notably comprises a fuse bulb 31a which breaks when an ambient temperature reaches a limit temperature. 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.

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 room 1 via the water drain 6b, and a closed position in the which the mixer 7 prohibits such circulation. The mixer 7, described below in Figure 6, advantageously comprises a Venturi type device, such as a pressure-generating member with conical internals which, by its design can only operate in one direction of circulation 16, that going from mixer 7 towards the water discharge 6b, and in fact creates suction only in the event of water circulation 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 to the water outlet 6a, to extinguish the fire. 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 .

[0100] The security device 5 also comprises a home automation center 14 which is remotely connected to a flow sensor 33 fitted to the water pipe 6. The flow sensor 33 is able to detect and notify a circulation of water inside the water pipe 6, such water circulation being caused by the rupture of the fuse bulb 31a.

[0101] 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.

[0102] 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 remote location 20, such as a bedroom, a living room, an office or the like.

[0103] The home automation center 14 is also equipped with trigger means 25 of a main power differential circuit breaker 35 as well as a connected auxiliary module or connected position transmitter 35a confirming the triggering supplying the room 1.

[0104] These arrangements are such that the fire inside the room 1 is quickly contained, or even extinguished, from the diffusion of water and extinguishing agent 9a in the room 1 via the diffuser 31.

[0105] These arrangements are also such that the user is quickly warned of the occurrence of the fire from the implementation of the transmission means 17 and the information means 19, as described previously.

[0106] These arrangements are such that the flow sensor 33 informs the user as soon as the fire occurs. Instantly, the home automation center 14 notifies the user and acts on the various alarms. Preferably, the home automation unit cuts off the electrical supply to the premises 1. The home automation unit 14 preferentially activates the trigger of the main power differential circuit breaker 35. The connected auxiliary module or connected position transmitter 35a confirms and notifies the user of the opening of the main power differential circuit breaker 35 via the home automation unit 14.

[0107] In Figure 5, 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 pipe d The water supply 2 is greater than 2 bars.

[0108] 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. water 2 and a water outlet 6b corresponding to the inlet fitted to a water heater 40. The safety device 5 comprises a safety group 41 which includes a safety valve 42 equipped with a flow sensor 33. The sensor flow rate 33 equips for example a drain pipe 43 of the safety valve 42.

[0109] The security device 5 also comprises a home automation unit 14 which is remotely connected to the flow sensor 33 fitted to the safety valve 42. The flow sensor 33 is capable of detecting a circulation of water at the interior of the drain pipe 43, such water circulation being caused by an excessive flow caused by the malfunction of the safety valve 42 of the safety group 41 either by wear or by the excess presence of calcium carbonate, limescale affecting the water heater 40.

[0110] 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.

[0111] 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 room 1, such as a bedroom, a living room , an office or the like.

[0112] The home automation center 14 is also equipped with means 44 for actuating a solenoid valve 45 equipping the water pipe 6, so as to cause a closure of the the solenoid valve 45 in the event of detection of a leak, excessive drain flow affecting the water heater 40. The home automation center 14 is also equipped with actuation means 25 of a trigger 46 equipping the individual power circuit breaker supplying the water heater 40.

[0113] These arrangements are such that the flow sensor 33 informs the user as soon as the flow is significant and/or excessive. Instantly, the home automation center 14 notifies the user and acts on the various alarms. Preferably, the home automation center cuts off the individual electrical supply to the water heater 40 and can also cut off its water supply via the solenoid valve 45. A connected auxiliary module 46a confirms by notification the electrical isolation of the water heater 40. The connected auxiliary module or connected position transmitter 46a as well as the connected trigger 46 are connected, mechanically hooked to the individual power circuit breaker. Thus, a significant saving of water and electricity is achieved for installations where the safety valve 42 has been defective for months due to a sneaky leak, sometimes visible only on the invoice.

[0114] These arrangements are also such that the user is quickly informed of the occurrence of the consequent leak from the implementation of the transmission means 17 and the information means 19.

[0115] We note at this stage of the description that the security device of the present invention is capable of comprising at least one of the variants described above, taken alone or in combination.

[0116] In Figure 6, 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 liquid circulation 51. The Venturi type device 50 is itself in fluidic relation 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 the 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 of 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 water circulation occurs inside of 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 3 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.

[0117] In Figure 7, the diffuser 31 includes an enclosure 60 which houses the thermal bulb 3 la. The thermal bulb 3 la 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 of the cap from the flue as well as the diameter of the flue. 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 hold the thermal bulb 3 la in support against the shutter 61 obstructing the fluid passage of the pipe 6.

[0118] In Figure 8, 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 pipe d The water supply 2 is greater than 2 bars. Its aim is to create a water curtain 6c from a higher point giving access to room 1 which can be a staircase, a corridor, a chemical storage room, reserve, archives, office or other which not only makes it possible to avoid a propagation towards another room, a passage but also to considerably reduce the infrared radiation generated by the flames which in turn degrade, decompose in the form of vapors and/or gases the elements transformed into fuel. This reduction in infrared radiation by this water curtain 6c cools the combustion vapors, preventing the formation of gases, the expansion of soot, preserves the adjoining room 1 and the evacuation of possible occupants without risk of serious burns in passing behind this curtain of water.

[0119] In Figure 9, a diffuser 31 is shown which constitutes the security device 5 of the room 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 the room 1 on a wall 38 or a ceiling in the case where the access does not have a lintel. The water drain 6b is equipped with a diffuser 31 which is capable of diffusing water after opening of the solenoid valve 15 when a fire appears in room 1. According to this variant, the diffuser 31 is cylindrical and is obstructed at its two ends. It is equipped in the upper part with a water inlet 80 and is provided in the lower part with an alignment of calibrated orifices 70 of approximately 0.9 mm in diameter making it possible to diffuse water forming a water curtain 6c , in other words a water barrier, on a 60' access communicating with room 1. It is also likely to be of varied colors for discretion if necessary.

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 a 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 only above of access 60' to room 1 via the water drain 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 .

[0121] The security device 5 also comprises an electronic card 10 which is connected via a telephone type cable 10a with a temperature sensor 11 equipping the room 1 to measure a temperature T'2 of the room 1. The electronic card 10 is provided with means 12 for comparing the temperature T'2 of room 1 measured with a threshold temperature T2. If the temperature T'2 of room 1 exceeds the threshold temperature T2, communication means 13 fitted to the electronic card 10 communicate remotely with a home automation unit 14 which is able to remotely open a solenoid valve 15 fitted to the water pipe 6. 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. 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 in Figure 6, 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 evacuation 6b, and actually creates suction only in the event of sufficient water circulation in the water pipe 6. It there results a mixture of the extinguishing agent 9a and the water inside the water pipe 6, this mixture circulating inside the latter until the water evacuation 6a, to limit , or even stop the propagation of infrared radiation originating from the spread of fire.

[0122] 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 to inside the water pipe 6, such water circulation being caused by the opening of the solenoid valve 15.

[0123] 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.

[0124] 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 remote location 20, such as a bedroom, a living room, office or similar.

[0125] The home automation center 14 is also equipped with means 44 for actuating the solenoid valve 15 causing a flow rate, a speed and therefore a depression in the mixer 7 on the water pipe 6. Thus the flow rate is confirmed, and notified to the user by the flow sensor 33.

[0126] The home automation center 14 is also equipped with triggering means 25 of a main power differential circuit breaker 35 as well as a connected auxiliary module or connected position transmitter 35a supplying the room 1 which confirms and notifies the user the opening of the main power differential circuit breaker 35 via the home automation unit 14.

[0127] These arrangements are such that the fire inside the room 1 cannot propagate towards the room 1 by the creation of the water curtain 6c from the water inlet and the agent fire extinguisher 9a inside room 1 via the water drain 6a.

[0128] These provisions are also such that the user is quickly informed of the occurrence of a barrier against the spread of fire from the implementation of the transmission means 17 and the information means 19.

[0129] Furthermore, in the event of an earthquake, the priority is to protect yourself. Insulate equipment powered by gas such as boilers, ovens, gas stoves and others or the electricity supplied installing ceiling fans, soldering or ironing irons, household appliances, workshop machines and others are also a priority in order to avoid accidents, explosions and fires. Power plants are equipped with seismic sensors to isolate the high-voltage distribution network. The shock wave travels approximately 100 km in several tens of seconds. Room 1 is probably much closer to the epicenter than the power plant. An earthquake can rupture a gas line, move electrical equipment, tear out live wires and cause other property damage. However, some excess accidents are avoidable. For individuals, these actions can be carried out very quickly using a connected seismic sensor. Acting as quickly as possible is important. The following equipment therefore makes it possible to act instantly and therefore to avoid further accidents. By design it is fun.

[0130] Also, a support fixed to a wall on which an electrically insulating horizontal plate on which several rings of approximately 1.2 mm in section, concentric and electrically conductive are fixed and positioned, the even ones of which are only connected to each other and the odd ones are also linked only to each other. On the first even calibrated ring, the plate is pierced with a calibrated hole allowing a ball of a given mass, conductive, approximately 20 mm in diameter to be placed. This ball will come out of its housing as soon as it undergoes movements caused by the plate which are that of the wall of the room on which it is fixed which only reflects the wave of the movement of the wall generated by an earthquake greater than approximately 4 on the RICHTER scale as a precaution. In order to optimize the slightest contact of the ball between two rings during an earthquake or similar, they are spaced so that the ball cannot touch the plate, thus avoiding possible parasitic rebounds, and, due to its properties intrinsics associated with the force of gravity to allow touching only, very quickly and simultaneously an even and odd ring regardless of its random movement. These changes in position relative to the initial position are analyzed and compared immediately by the autonomous electronic card, which will immediately transmit the movement of the ball, corresponding to reaching the alert threshold, to the home automation center with which it communicates in permanence. Instantly, the home automation center will trigger the actuators, preselected orders. Safety of the electrical circuit, gas, unlocking/locking of doors, and others is established. The occupants of the premises do not have to worry about a possible risk of further accident, at this moment the only concern is to get to a safe place.

[0131] Thus, in Figure 10, a room 1 is equipped with a gas supply pipe city or natural or other 2a which is intended to supply gas to the room 1. Typically, a gas pressure reigns inside the gas supply pipe.

[0132] The premises 1 is advantageously provided with a security device 5 for the premises 1. The security device 5 comprises a gas pipe 2a which extends between a gas inlet equipping the gas pipe 2a and a gas pipe 2a. corresponding gas 6d equipping equipment 95, 95a, such as a boiler 95a, and/or a gas cooker 95, and/or a fireplace or the like. The security device 5 comprises an electronic valve 45a capable of isolating and closing the gas circulation on the gas pipe 6d. The electronic valve 45a can also be a 3-way valve allowing the gas contained in the gas line 6d to be evacuated and depressurized towards a vent 6e.

[0133] The security device 5 also includes a home automation control unit 14 which is remotely connected to an electronic valve 45a or the electromagnet control allowing release by a door opening or closing mechanism or other.

[0134] 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.

[0135] 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 room 1, such as a bedroom, a living room , an office or the like.

[0136] The home automation center 14 is also equipped with means 44 for actuating the electronic valve 45a fitted to the gas pipe 6d, so as to cause a closing and tilting of the electronic valve 45a in the event of detection of an earthquake. The home automation center 14 is also equipped with means 25 of actuation of a main power differential circuit breaker 35 equipping the general power circuit breaker supplying the room 1.

[0137] These arrangements are such that a seismic sensor 91 informs the user as soon as the alert threshold is reached. Instantly, the home automation center 14 notifies the user and acts on the various alarms. Preferably, the home automation center cuts off the electrical power supply to the main power differential circuit breaker 35 and can also cut off its gas supply via the electronic valve 45a. A connected auxiliary module or connected position transmitter 35a confirms by no- tification the electrical insulation of the premises 1. The main power differential circuit breaker 35 or connected position transmitter 35a as well as the main power differential circuit breaker 35 are connected, mechanically hooked to the power supply circuit breaker. Thus, excess accidents, risks of fire outbreaks and explosions due to possible gas leaks associated with damaged electrical equipment under voltage are automatically and quickly eliminated.

[0138] The security device 5 also comprises an electronic card 10 which is connected directly with the seismic sensor 91 equipping the room 1 to measure a movement of the wall 38 of the room 1. The electronic card 10 is provided with comparison means 12 d 'a position of the wall of the room P' 1 measured with a threshold position P2. If the position of the wall of the room P' 1 exceeds a threshold position P2, communication means 13 fitted to the electronic card 10 communicate remotely with a home automation center 14 which is able to remotely close the electronic valve 45a fitted to the pipeline. gas 2a. The electronic valve 45a is placed on the gas pipe 2a upstream of the equipment 95, 95a. Closing the electronic valve 45a causes the gas circulation to stop inside the gas line 6d.

[0139] These arrangements are also such that the user is quickly warned of the occurrence of the level being reached, the earthquake alert threshold resulting from the implementation of the transmission means 17 and the means of information 19.

[0140] We note at this stage of the description that the security device of the present invention is capable of comprising at least one of the variants described above, taken alone or in combination. Power plants are equipped to isolate the electrical distribution, however, the earthquake does not necessarily occur very close to the power plants and it is therefore important to act quickly.

[0141] In Figure 11, a sectional view of the seismic sensor 91 includes a transparent enclosure 75 which may be of plexiglass material placed on an electrically insulating plate 90 which may be of the bakelite type. The transparent enclosure 75 houses a conductive ball 47 of substantial mass in order to promote its movements in the horizontal direction. The electrically insulating plate 90 includes a calibrated hole in its center as well as even concentric conductive rings 49 and odd concentric conductive rings 50 with a section of approximately 1.2 mm. The odd concentric conductive rings 50 are electrically connected to each other by an odd conductor 50a in the same way as the even concentric conductive rings 49 are connected to each other by an even conductor 49a. The conductors 49a and 50a are connected to the electronic card 10. The rings 49, 50 are spaced so that when the conductive ball 47 comes to move to a position 47' and does not bounce off the electrically insulating plate 90, without touching it in a space 92 and there is systematically contact between the odd concentric conductive rings 50 and the rings even concentric conductors 49. In a normal situation, the conductive ball 47 is placed in a calibrated orifice 51 combined with the section of the first odd ring which is in connection with the even conductor 49a, creating contact with the conductor a connection 48 positioned under the conductive ball 47. As soon as a vibratory movement of the wall 38 and therefore of the seismic sensor 91 appears generated by a tremor, earthquake exceeding a threshold greater than 4 on the Richter scale, the conductive ball 47 will exit the orifice calibrated 51 and therefore elimination of contact with the connection 48. The conductive ball 47 will move randomly to position 47' for example on the horizontal plane and very quickly and automatically bring into contact an odd concentric conductive ring 50 and a concentric conductive ring even 49. The possible amplitude of the vertical movement of the conductive ball 47 is also limited by the height of the transparent enclosure 75. The position 47', however brief it may be, of the conductive ball 47, for example, goes through the conductors 49a and 50a be recognized by the electronic card 10. This electronic card 10 will instantly signal the reaching of the alert threshold to the home automation center 14 to activate its connected actuators and secure the premises 1.
