Fire Detector IP 212 45 - own fireman in the house

Repeatedly confirmed in the course of numerous experiments: a person in a dream does not smell smoke. According to the sad statistics of the Ministry of Emergency Situations, the overwhelming majority of people die in a fire in a dream. And it does not matter what causes a fire. Dropped from the hand asleep cigarette (about 80% of all dead in the fires), a faulty oven, a short circuit wiring (which all do not reach the hands to replace). There can be many reasons, but the result, alas, is one. Fire Detector IP 212 45 - a device that allows you to protect loved ones from the fire element, easy to operate and more than affordable.

Danger to human combustion products

During combustion of organic compounds, oxygen is oxidized in them and oxygen is released from CO 2 dioxide and carbon monoxide CO. At once we will specify, ИП 212 45 reacts equally effectively on both these connections.

With the normal combustion of hydrocarbons, the CO 2 carbon dioxide habitual to us is formed. Its normal content in the air is 0.03 ... 0.05%. When burning indoors with no ventilation, its concentration rises rapidly. And breathing in air with 30% CO 2 for at least an hour is a lethal dose for an adult healthy person.

More insidious carbon monoxide CO, better known as carbon monoxide. It has only one attached carbon atom, is formed when combustion occurs with a lack of oxygen. And in a fire occurring in an enclosed space, this is the norm. So, the concentration in the inspired air at least 0.4% leads to death in less than half an hour, a concentration of a percent or more kills almost immediately.

But this is not all "chemistry", present in a burning building. The combustion products of some polymers are chemical weapons in their composition.

Description of the device ИП 212 45

The shape of the device is somewhat like a flying saucer of aliens. Made of high quality plastic. The diameter of the disk is about 100 mm, the height is about 60 mm.

Detector IP 212 45 works by the principle of refraction of light rays when passing them through an optical medium. The appearance of smoke in the air, soot causes a change in the optical properties of the atmosphere. The sensor responds to this change and turns on the alarm.

Moreover, the FE 212 45 will not be bothered by the owners, reacting to changes in air humidity (evaporation from a boiling kettle). The photosensitive elements are tuned in such a way as to react to smoke, as well as the excess in air concentrations of CO and CO 2 .

Detector activation is a combination of light indication and a sound signal. And the sound signal is designed to cause maximum discomfort, so ignore the smoke in the house with IP 212 45 will not work. Even a person who sleeps in a sound sleep (and even in a state of intoxication) is guaranteed to be awakened by the signal being given.

Acquisition and installation

The purchase of this or similar device is not a problem today. You can buy it at almost any consumer electronics store. Popular online stores also have not bypassed 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. It is enough to place a toothpick, a rod from a fountain pen or other thin object into the center of the device (there is a small hole). The foreign body will play the role of smoke, and the device will work.

ИП 212 45 works from a food element 9В - "Crones". It is worth to look at the date of the battery life, so you do not have to immediately change it.

A detector is installed on the ceiling. First two self-tapping screws (if the ceiling is wooden) or a small dowel-nail is attached a special plate. Then the device itself is pressed against it lightly and fixed by an easy turn of the body by about 30 °. The flashing of the LED indicator once in about 40 ... 50 seconds indicates that you are already under reliable protection of the stand-alone fire detector.

Rules of operation

No trouble to the owner of the house, the smoke detector IP 212 45 will not deliver. Once at about 3 months, he will start without any apparent reason to issue one short "squeak" per minute. Thus, the appliance signals that a power change is necessary.

Anyone who at least once changed the batteries in the remote control of the TV, will be able to change it in the detector. When replacing the battery, it is recommended to blow out the bottom of the appliance (grill) with compressed air thoroughly or to vacuum it.

An autonomous fire detector will not become superfluous in the family, especially with young children or elderly relatives.
