Fire safety has not lost and, probably, will not soon lose its relevance. Despite the constant updating of the list of building materials, the improvement of their characteristics (including the combustibility, 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 natural organic materials, such as wood, paper, all kinds of natural fabrics, etc. in everyday life. And even vice versa: the tendency of recent decades is the mass rejection of synthetics in favor of the whole “present”.
To know is to survive
In any safety instructions and recommendations, in the internal firefighting guidance documents, you can read that rescuing people is a top priority for both emergency services and the facility’s administration. As practice shows, most of the tragic results of fires in buildings with a massive stay of people are due to untimely evacuation measures.
Rescue people from the roofs of buildings using helicopters, from the windows of buildings using high-rise stairs - special cases. Such events require time to prepare, attract special equipment, the delivery of which is also not instant.
The most effective way to save is still timely evacuation. The score in the literal sense of the word can go for seconds. And here, the proper operation of the warning system plays the most important role.
Fire alert methods
One of the requirements for fire safety in Soviet times was the presence in the settlements of some kind of device to alert residents. In the villages near the house, the headmen hung a piece of rail on a chain and, in case of alarm, pounded it with a piece of iron. Today, there are much more ways to alert people about a fire. This is usually a combination of the following methods:
- The sound signal (sometimes coupled with lighting effects) so that it can be heard in all rooms of the building.
- Voice messaging using loud-speaking devices.
- Turning on the illumination of exit direction signs, as well as lighting of the evacuation paths themselves.
- Opening doors, locks and hatches of emergency exits, carried out remotely.
Manual fire detectors (in fact, this is the "alarm" fire button) are the very first link (along with automatic) in the alarm. Not always automation is ahead of man.
Technical Specifications of Model 513-10
- protection against accidental switching on of the system (protective transparent screen, the design of which provides for the possibility of sealing);
- You can turn on IPR 513-10 only with a force of more than 15 N (about one and a half kg), after activating the "alarm" remove your finger from the button, the contact is saved;
- operating voltage 9 ... 30 volts;
- current consumed in sleep mode, 0.05 mA;
- the inclusion of the IPR 513-10 button provides a resistance of 0.5 kOhm;
- III class of protection against dangerous factors of electric current;
- to connect the device to the system using a two-wire cable (alarm loop);
- to visually determine the specific detector from which the signal is supplied, a red backlight is provided, which lights up in the "Fire" mode;
- IPR 513-10 has a shockproof housing.
How does it connect
The IPR 513-10 detector is attached to the wall using two threaded fasteners. An anchor , a nail, an anchor - anything will do. The marking for mounting is extremely simple - the holes are located on one horizontal line at a distance of 55 mm from each other.
The mounting height of the device above the floor, recommended by the manufacturer, is approximately one and a half meters.
Before mounting on the wall, the front part is removed - at the top there are two locks (locks), clicking on which, it can be easily removed. After that, the base is attached to pre-prepared holes, and an alarm loop (AL) is connected to the terminals.
The final touches are snapping into place of the top cover, and sealing the protective screen (sealing is usually done after checking the system’s operability).
How exactly is connected to the IPR 513-10 circuit? The connection scheme depends on the device with which the detector will have to work. The fact is that the current in the "Fire" mode passing through a manual detector should not exceed 20 mA. To such systems as PPK-2, Nota, Luch, Rainbow and some others (voltage in the loop 9 ... 30V, the detector resistance during operation does not exceed 1000 Ohms) IPR 513-10 is connected directly.
Operation of the device with other systems requires connection through shunts (compensating resistances).
