Fire safety is not lost and, probably, notwill soon lose its relevance. Despite the constant updating of the list of building materials, the improvement of their characteristics (including flammability, as well as the toxicity of products formed during combustion), a significant part of them is combustible. In addition - it is unlikely that a person is ready to completely abandon the everyday life of natural organic materials, such as wood, paper, all kinds of natural fabrics, etc. And even on the contrary: the tendency of the last decades is a massive rejection of synthetics in favor of everything "real".
In any instructions and recommendations onsecurity, in the internal guidance documents of the fire department, you can read that saving people is a priority task, both for rescue services and for the administration of the facility. As practice shows, most of the tragic results of fires in buildings with massive people stay are due to untimely carried out evacuation measures.
Rescuing people from the roofs of buildings with the help ofhelicopters, from windows of buildings with the help of high-altitude ladders - special cases. Such activities require time for preparation, attraction of special equipment, the delivery of which is also not instantaneous.
The most effective way of saving is stillis a timely evacuation. The account in the literal sense of the word can go on for a second. And then the correct operation of the warning system plays the most important role.
One of the requirements of fire safety inSoviet time was the presence in the settlements of any device to alert residents. In the villages near the house the elders hung a piece of rail on a chain and, in case of an alarm, pounded it with a piece of iron. Today there are much more opportunities to alert people about a fire. Typically, this is a combination of the following ways:
Manual fire detectors (in fact this is the "alarming" fire button) are the very first link (along with automatic) in the alarm signal. Automation is not always ahead of a person.
The detector IPR 513-10 is fixed to the wall with the help oftwo threaded fasteners. A dowel, a nail, an anchor - will do anything. The marking for fastening is extremely simple - the holes are located on one horizontal line at a distance of 55 mm from each other.
The height of mounting the device above the floor, recommended by the manufacturer, is about one and a half meters.
Before installation on the wall, the front part is removed -at the top are two locks (lock), pressing on which, it can be easily dismantled. After that, the base is attached to pre-prepared holes, and the alarm loop (AL) is connected to the terminals.
The last strokes are snapping in place of the top cover, and sealing the protective screen (the sealing is usually done after checking the operability of the system).
How exactly is connected to the circuit of the IPR 513-10?The connection scheme depends on the device with which the detector is to operate. The fact is that the current in the "Fire" mode, passing through the manual detector, should not exceed 20 mA. To such systems as PPK-2, "Nota", "Ray", "Rainbow" and some other (voltage in the loop 9 ... 30V, the resistance of the detector when it is operated does not exceed 1000 Ohm). The IPR 513-10 is connected directly.
Operation of the device with other systems requires connection via shunts (compensating resistors).
