Smoke detector optic-electronic address-analogue DIP-34A

The movement ahead of mechanics and electronics, the development of technology could not but affect the devices, mechanisms and ways to protect people and property from the fire. Once upon a time in the reign of Ioana IV, the introduction of round-the-clock duty on special towers - calancers was progressive. Such "warning system" helped to take timely measures to prevent burnout of the whole city, allowing to limit the destruction of several buildings.

Today, a key role in providing fire safety belongs to electronics. Smart machines are in a position not only to detect the source of ignition at the earliest stage and to report this, but also to begin extinguishing it.

"Eyes" of any fire-fighting system are detectors - devices that directly react to certain fire factors and form the corresponding electrical signal. The device DIP 34A has a number of unique technical characteristics, which makes it possible to increase the efficiency of fire-fighting automatic systems by an order of magnitude.

Principle of operation

The very first detectors used in systems produced in the Soviet times reacted only to temperature. Fused with low-melting (about 60 ° C) solder, the elastic plates were separated when heated, the electrical contact disappeared, which was fixed by the receiving device.

Modern detectors, in particular the DIP 34A under consideration, work differently. It is known that the optical properties of gases strongly depend on the presence of impurities in them, as well as on the temperature.

Particularly sensitive to the slightest changes in the gas-air mixture are infrared rays. These physical properties also use the DIP 34A detector for early detection of a fire.

Application area

The device consists mainly of an LED - a source of infrared radiation and a receiver - a special lens system and a photosensitive element. A small air gap between them is all that DIP 34A needs to monitor the state of the protected facility. The device under consideration is intended for continuous monitoring of the air inside the enclosed premises and the issuance of a signal in case of any changes. By the way, not only about the occurrence of a fire can inform DIP 34A. The characteristics of this detector allow you to distinguish between smoke in the room from getting into the diffuser of dust. Intelligent electronics in the processing of the signal is distinguished even by the smoke of a fire from cigarette smoke (negligent smokers are a real scourge of fire-fighting systems, the source of 90% of all false alarms).

Features and specifications

With the full characteristics of the device DIP 34A can be found by reading the instructions, here are just some of its distinctive data:

- an intelligent signal processing system capable of distinguishing the occurrence of a fire from dusting a room, getting into a diffuser of insects, and also the presence of tobacco smoke in the air;

- the widest temperature range (from 30 degrees below zero to 55 degrees Celsius) makes it possible to use the device both in heated rooms and unheated rooms;

- extremely small inertia of operation - no more than 10 seconds;

- a small current consumption in the operating mode - about half a milliampere;

- service life 10 years.
