Fire safety is an important aspect of human life. Each of us, while studying at work, at home or elsewhere, must be protected from external threats, including fire. Timely detection of the source of danger can help to quickly find and eliminate it, protecting more than one life, as well as minimizing material costs. Aspiration detectors are an effective way to ensure the safety of people and premises, to protect them from fires. The features of these devices will be discussed in the article.
General information
The word "aspiration" has a Latin origin. Translated aspiro means "inhale." It is this word that gives an idea of the general mechanism of the device. In an aspiration fire detector, it consists in the selection of air masses within a certain controlled room. The extracted air is analyzed in order to timely detect threats and identify combustion products.
The main task for which specialists developed such a device is to search for areas where the fire has just begun to spread and has not yet managed to create a serious danger.
Latest technology
Aspirators, according to experts, currently account for 12% of the entire fire systems market in Europe. Their forecasts indicate that this indicator will only grow. The development of new types of aspirators makes it possible to more actively use the device, expanding the scope of its use, and also to fully realize in practice all the advantages of such systems in a wide variety of fields of activity.
The technology due to which the detector operates is one of the most advanced among similar devices aimed at early detection of a fire source. The idea is to create an air stream that the system absorbs directly from the controlled room, as well as its further transfer to a special optical fire detector. Thanks to this mechanism of operation, aspiration smoke detectors can detect a fire at the earliest stages of their occurrence - even before a person can sense or see smoke. The device will record the danger even in the process of smoldering objects, heating surfaces (evaporation of insulating substances on cables, etc.).
Principle of operation
Announcer fire aspiration IPA comprises a number of pipes combined into a system where there are special openings for air intake and an aspiration device equipped with a turbine to maintain air flow.
The principle of operation of the device is quite simple, but effective. Sensors that are installed in the system carry out optical control of the received air. Given the level of sensitivity required for the device, laser or LED detectors can be installed in it. The pipes are mounted in the room where the air analysis will be carried out , while the suction device, the control unit, is located in any other place from where it is convenient to maintain and control the system.
Application area
Today, the most successful fire protection is provided by suction detectors equipped with ultra-sensitive laser smoke detectors. Such systems are excellent for ensuring the fire safety of power plants with a different principle of energy production, large hangar rooms with aviation, automobile and other types of equipment, rooms intended for storing fuel and combustible mixtures, production areas of increased sterility, hospital buildings with diagnostic equipment and other premises with high-tech devices.
Initially, systems were developed specifically for objects of increased importance, the safety of which was a priority. The safety of material assets, large amounts of money, expensive equipment, the replacement of which can entail serious expenses, as well as stopping the entire production process, is the main goal of aspiration detectors. In such places, it is extremely important to find and eliminate the resulting threat as soon as possible at the moment when smoldering did not begin before open fire appeared.
It is equally important to ensure the safety of rooms with a large crowd of people. There systems should have a particularly high level of sensitivity compared to standard devices. It can be large exhibition centers, cinemas, stadiums, entertainment and shopping centers. At objects of this kind, a preliminary signal, which is received only by the building staff, makes it possible to eliminate the cause of the fire without resorting to mass evacuation, and, accordingly, to panic among visitors.
Benefits
The IPA aspiration detector has several advantages over traditional systems:
- To point-type devices installed in large areas, smoke may simply not reach. In this case, the aspirator ensures that air masses get through all openings from any part of the room. Ventilation, air conditioners will not be able to affect the quality of the system;
- This type of detector minimizes the effect of air stratification in a high room, where warm air, located closer to the ceiling, interferes with the flow of smoke and prevents a timely fire reaction.
- Often, designers face serious problems in decorating rooms where a fire safety system makes it impossible to implement an idea. The aspiration type of the device allows you to hide all the external structural elements. It is enough to make a couple of holes under the ceiling, the diameter of which is a couple of millimeters. It is impossible to make out even with their armed eyes.
conclusions
Ensuring the safety of valuable equipment and people at a high level will help the suction system.
Efficiency of work will allow avoiding serious material costs, stopping the production process and human casualties, without requiring complicated care or investing large amounts of money for its installation.
