An automatic fire-extinguishing system can be operated in three ways:
1) through termoshnura, steer fire in the protected space;
2 2) through special sensors mounted on the inside of the hood;

Magee against fire
Under the hood Volga fire breaks out.But why none of the people gathered around to the trunk thrown in search of a fire extinguisher?
Just a couple of seconds after the start of the fire engine compartment showing white smoke.Fire extinguished!He coped Mag automatic fire extinguishing system, the tests that we have just attended.
. For the first time, the effectiveness of firefighting theme, we asked six months ago (see AR № 23, 2000). During comparative test road extinguishers revealed that of the nine samples tested, only two have coped with the task of extinguishing the fire podkapotnom space in the car. The remaining seven have worked or not, or should allocate poisonous gases, or reinforce burning!
But even with intact suddenly emerged extinguisher to extinguish the fire in the engine compartment is not easy. Imagine - it must still be able to open the car hood when gasoline flames beneath it. But firefighters contend that in a few tens of seconds after the start of the fire locking bonnet can to wedge from overheating.
Automatic fire extinguishing system is, of course, better than conventional hand-held fire extinguishers. But familiar with such systems is it that professionals. For example, since 1998, automatic fire-extinguishing systems should necessarily be equipped with armored vehicles, all-not just cash machines, but also the so-called hidden booking cars. They podkapotnom space, according to the requirements of the normative documents, should be installed at least two automatic fire extinguishers.
And is there a similar system, which can use "civil" motorists?
Specialists located in the center of Moscow, Federal Union of "double technologies created its" automatic fire extinguishing system for installation in Mag podkapotnom space and in the boot of cars. . During our tests, two Mag system was installed under the hood normal Volga. Your choice agregatonositelya" specialists "Union" explained simply: "We already had a case where Volga fire with 406-m vpryskovym" engine ". Normal history - weakened artery clamps fuel and gasoline spilled directly to the exhaust manifold. . Well, that all of our cars are equipped with Mag and on the car system worked immediately ... "
The method of firing tests "Alliance" was close to the one on which we have conducted comparative tests of fire extinguishers in St. Petersburg. The only difference was that Bader specialists burned gasoline, not poured in a round, and two rectangular protivnya. But with fuel tanks exactly the same set at the level of the engine, and gasoline okutereka the same one liter.
So the test be held. Petrol in protivnyah styles of the torch, after which zahlopyvaetsya hood. Here Magi come into play. Sinister sizzles and machine-okutyvaetsya dense white smoke.All the fires destroyed. But professional pozharnye-ispytateli from St. Petersburg lab for a time only failed to capture extinguisher.And how quickly the average driver will be able to find any in his car extinguisher?
The final scene firing tests and does the ability to hit the majority of motorists. After razveyalos cloud of white smoke, the driver sat for the rudder Volga, the engine has started, and left the car alone "battlefield"! Raging gasoline was redeemed Maga so quickly that in podkapotnom space is not affected, no wire or sleeve!
« "Topping" this device-aerozoleobrazuyuschy composition, the components of which specialists described as "the Union" refused. Breakwater, the military secrecy. Indeed, such a system originally designed precisely to the needs of the military for fighting fires missile at the compound and armored equipment.
It is simple, but interesting: extinguishing agent with the composition of putting out the fire ... wolf begins! In doing so, he devotes a large number of special spray, saturated with carbon dioxide gas. Gas fills the space podkapotnoe or car trunk and fire drowning. That is why the most effective Magi work in confined volumes, and while putting out a fire in the engine compartment hood is not open Volga-Magov "magic", ie aerosol salvation will volatilize.
Automatic detection of fire in the current Mag like this. Inside the volume, "which is responsible for" fire extinguisher, special paving termoshnur, reacting to an open flame or a rise in temperature.With 170 degrees sensor material "and" samovosplamenyaetsya like fuse cord, a fraction of a second message to the working fire extinguisher tel. Termoshnura The main drawback is that he is very sensitive to oil and gasoline under their impact cord becomes friable, and the speed of propagation of flame falling. So now, the developers of such systems using special sensors. If the temperature in the protected amount they give the electric impulse from the built-in condenser primers, in a special slot vvinchennomu extinguisher. This primers, as appropriate, and vosplamenyaet uglekislotnogo aerosol generator.
Incidentally, the concentration of carbon dioxide, according to the creators Maga, it is about as low in the exhaust car. All the rest protivoognevaya veil is a special powder, which, incidentally, is not aggressive towards the rubber, plastics and coatings paintwork. And after activation extinguisher powder can be easily remove wet cloth. Therefore, like automatic fire extinguishers is designed for installation in the cabin.
How much does it cost "magic" protection of the car? Specialists recommend that "the Union" to mount two Maga under the hood and one in the boot: that with the installation kit depending on the type of car would cost from 1000 to 1300 rubles. Lots of it or little? . Let us count. The most effective fire extinguisher our autumn tests cost 190 rubles. The term of service-2 years. Automatic fire extinguishers need to serve more than 5 years. Issued that automatic fire-extinguishing system is expensive roughly double the normal fire extinguishers.
НBut when it comes to keeping a car costing thousands or tens of thousands of dollars, these amounts seem ridiculous. Incidentally, now manufacturers of automatic fire extinguishing systems are trying to lobby for mandatory equipping all cars with automatic fire extinguishers. Their main argument is that such systems work quickly, operate independently of the surrounding skills and with a guarantee to put any ignition. Anyone who has never seen a car near the front, in response to such arguments pozhmet shoulders. But after our tests, we are inclined to support domestic producers of such systems. Incidentally, the import pozharnye-avtomaty much more expensive ...
