DE2345910A1 - Anti-fire spreading alarm systems - use thermostats with appropriate leads in conduits, which can accelerate warning of fire break-out - Google Patents

Abstract

The placement of fire alarm thermostats, the general properties of the circuits they feed, and the best arrangements for supplying them with power are described in a very general way. The thermostats may be enclosed in capsules or open, and are mounted at various points in a room or building. The leads associated with them are mounted in fireproof conduits and are of large cross-sectional area. The circuits fed by the thermostats consists generally of a relay, which in turn drives an optical or acoustic warning system. These should in both cases be standardized to ensure that their meaning is quickly appreciated.

Alarm system c ^e 0 eii Damage ^{vacation extension «}

Lumer again shocked us by the news! "" Your disasters. After a detailed study of the causes and effects it was predominantly decisive that the developing fires were not perceived in the initial stage. The preventive measures such as hand fire extinguishers, jfeuerv / honor, existing extinguishing water pipes, rescue operations for people etc. were mostly too late to be used. Comments like, "With timely use, the great expansion could probably have been avoided" are then an Eesume that is no longer useful. Particularly in the case of small collections or in the ITacn-t, those affected are sometimes made aware of the flames and ualms surrounding them, in which they can not help a little but rather cause damage or death themselves, especially for them The room for movement is missing or is cut off for them! Escape route is cut off, which is why when they realize no.ch panic ^{arises with their evil J 1} OIren.

in temperatures of the free atmosphere and their admixtures, for example Q, ualm and flames, as well as in contact with the aforementioned elements Surrounded by building materials and furnishings are installed and the thermostats are opened when a temperature to be determined is reached or closing a circuit to activate an alarm system «· It is well known that even the smallest amount of fire generates heat and heat. the the initially harmless heat of a damaging fire is replaced by the smoke, the flames, the atmosphere, the structures, the furnishings and the like. completely transferred to the affected premises or location.

As guards and receivers, thermostats wait for these changes in heat, in a recommended version, for example, which are encapsulated in housings with good thermal conductivity and which are ideally integrated into the atmosphere of the premises and locations protrude somewhat, which are about in Thermostats of this type are a good prerequisite for smoldering or flaming fires to transfer their temperature to them the earliest

The temperature transfer, which took place as quickly as possible, causes the through. '/ poor controlled contact or contacts of the thermostats the electrical Circuit of a relay opens or closes and the relay in turn switched the alarm system on and off. It is then done Alarm provided that the meaning of the './arming is generally known through appropriate publication ο

To be effective, it is also necessary that the thermostats

and the optical and acoustic warning devices in a sufficient number of corresponding 'resp. clearly visible and easily audible points are attached _o The special warning character of the alarm system can be improved by the color and sound tone, so that it does not lead to confusion with everyday light panels or rattle workers, that is, you have to choose a uniform color for the optical warning signs and a special uniform tone for the acoustic!

If necessary, there is the possibility that the alarm will go off on request at the same time or alone at the public fire station. »This may apply in special cases where buildings or other systems are unguarded during the holiday season or at night, which is common at Now that the damage fire is reported early enough, someone is always there to help after assessing the situation report to the fire brigade etr. passes on what In a certain sense, the early detection of fewer firefighting operations is the result should be.

Care must be taken to ensure that the relays and warning devices leading connection lines have a large cross-section and Are fire-proof insulated or fire-proof piped, as well as the warning devices should have fireproof caps. In observance of such details it was known previously not planned or worked for premises and locations, because the idea of early fighting of damaging fires never applies to the Evaluation and reporting of the first heat of the fire was considered or addressed, which according to the invention is the basis of the solution as a whole.

But this is the only way to prevent the "chaotic fires that have caused damage, which have so far been frequent and largely prevent fires.

In individual cases it must be carefully checked that the alarm system is your Electric power supply only from bra, secure supply lines of the public Electricity network, i.e. from cellar connections, otherwise obtained primarily from a separate power source.

Me invention provides security against fire surprises for everyone in your own home and those of others and protects you from unnecessary excitement after a fire has been reported, because after a fire reported by the alarm system has been extinguished or through premature manual operation, an automatic interrupter switches the warning devices on and off for a short time , after which the alarm system switches itself back to use. A manual switch can be used to check at any time whether the alarm system is reacting, in technical terms whether the system is armed »

The schematic drawing shows, for example, a room in which the Thermostats are attached to the walls, ceiling and floor o The metallic holder box 1 contains the line connections and conducts the heat of the building materials to part 2 where at a distance from the wall, ceiling and the thermostat with its contacts is built in from the floor. The recommended protrusion of part 2 into the atmosphere of the room gives a better guarantee for the sensitive transfer of the temperature from the room atmosphere without the transfer from, for example, the masonry

door adjusted or can also be temperature adjustable for adjustment to the respective land or weather conditions. At the set temperature, the thermostat opens or closes accordingly heat-influenceable device, the contacts of a circuit, whereby a relay is actuated, which in turn the alarm system turns on. The electrical conductors of the alarm system as a whole are fireproof insulated or laid in fireproof pipes. The alarm device has a fireproof cap. The power supply is provided from a fire-proof mains connection or from a separate power source. After deletion the alarm system automatically gives the all-clear via a breaker. The same process can be carried out if it is expedient initiate a shutdown of the alarm system manually. By means of a hand switch you can check that the alarm system is intact at any time

The advantages of the invention are that there is an early source of fire for everyone Those present in the local area are reported and, if necessary, they are woken up in good time at bedtime. If you are absent, the Brandmaldung can be switched to every third .. For children's and old people's homes, Hotels, dance halls, assembly rooms UoS. Where is the invention evaluation particularly important? This includes the costs for an alarm system of the kind described in no relation to the suffering and pain as to the annihilations of the increasing large fires on an ongoing basis and so far without a real preventive measure.
