Repeatedly confirmed in the course of numerousexperiments: a person in a dream does not smell the smell of smoke. According to the sad statistics of the Ministry of Emergency Situations, the vast majority of people die in a fire in a dream. It does not matter what causes the fire. A cigarette that fell out of the hands of a fallen asleep (about 80% of all those who died in the fires), a malfunctioning stove, a short circuit in the wiring (which all hands cannot replace). The reasons may be many, but the result, alas, is one. Fire detector IP 212 45 is a device that allows you to protect loved ones from fire elements, easy to operate and more than affordable.
During the burning of organic compounds, the carbon they contain is oxidized by oxygen and the release of CO dioxide.2 and carbon monoxide CO. At once we will specify, PI 212 45 reacts equally effectively to both these compounds.
During normal combustion of hydrocarbons, carbon dioxide CO, which is familiar to us, is formed.2. Its normal content in air is 0.03 ... 0.05%. When burning in a closed room with lack of ventilation, its concentration is rapidly increasing. And inhalation of air with 30% CO2 for at least an hour - a lethal dose for an adult healthy person.
More insidious carbon monoxide CO, moreknown as carbon monoxide. It has only one attached carbon atom, is formed when the combustion occurs with a lack of oxygen. And in a fire that occurs indoors, this is the norm. So, the concentration in the inhaled air of at least 0.4% leads to death within less than half an hour, the concentration in percentage and more kills almost immediately.
But this is not all "chemistry" that is present in the burning building. The composition of the combustion of some polymers in its composition is a real chemical weapon.
The shape of the device is somewhat similar to a flying saucer of aliens. Made from high quality plastic. The disc diameter is about 100 mm, height - about 60 mm.
The FE 212 45 detector works according to the principlerefraction of light rays when passing them through the optical medium. The appearance in the air of the premises of smoke, soot causes a change in the optical properties of the atmosphere. A sensitive sensor responds to this change and triggers an alarm.
Moreover, FE 212 45 will not be wastedowners, reacting to changes in air humidity (evaporation from a boiling kettle). The photosensitive elements are set up in such a way as to react to smoke, as well as the CO and CO concentrations in air2.
Detector triggering isset of light indication and sound signal. Moreover, the sound signal is designed to cause maximum discomfort, so ignoring the smoke in the house with IP 212 45 will not work. Even a person who is sleeping soundly (and even intoxicated) will be awakened with a given signal.
Purchase of this or similar devicetoday is not a problem. You can buy it at almost any consumer electronics store. Recently popular online stores also have not avoided this product.
When buying, you need to check the device.In order to test the detector, it is not necessary to fumigate it with smoke. Enough in the center of the device (there is a small hole) to put a toothpick, a rod from a pen or other thin object. The foreign body will play the role of smoke, and the device will work.
IP 212 45 is powered by a battery 9V - "Crown". It is worth looking at the expiration date of the battery so that you do not have to immediately change it.
Install the detector on the ceiling.First, a special plate is fixed with two self-tapping screws (if the ceiling is wooden) or small dowels-nails. Then, the device itself is slightly pressed against it and fixed by a slight turn of the body approximately 30 °. Blinking of the LED indicator once in about 40 ... 50 seconds indicates that you are already under reliable protection of the autonomous fire detector.
No trouble to the owner of the house smoke detector212 45 will not deliver. Once in about 3 months, he will begin, for no apparent reason, to publish one short “squeak” per minute. In this way, the device signals that a power supply is required.
The one who at least once independently changed the batteriesin the TV remote control, can change it in the detector. When replacing the battery, it is recommended to thoroughly blow the lower part of the device (grate) with compressed air or vacuum it.
An autonomous fire detector will not become redundant in a family, especially with young children or elderly relatives.
