The forward movement of mechanics and electronics, the development of technology could not but touch upon devices, mechanisms and methods of protecting people and material assets from fire. Once in the reign of John IV, the introduction of round-the-clock duty on special towers - kalanchs was progressive. Such a “warning system” helped to take measures in time and prevent burnout of a whole city from burning, allowing to limit the destruction of several buildings.
Today, electronics plays a key role in ensuring fire safety . Smart cars are able to not only detect a source of ignition at an early stage and report it, but also begin to extinguish it.
The "eyes" of any fire-fighting system are detectors - devices that directly respond to certain fire factors and form an appropriate electrical signal. The DIP 34A device has a number of unique technical characteristics that can significantly increase the efficiency of automatic fire systems.
Principle of operation
The very first detectors used in systems manufactured back in Soviet times reacted only to temperature. Soldered by fusible (about 60 ° C) solder, elastic plates were disconnected when heated, the electrical contact disappeared, which was recorded by the receiving device.
Modern detectors, in particular the considered DIP 34A, work differently. It is known that the optical properties of gases strongly depend on the presence of impurities in them, as well as on temperature.
Infrared rays react especially subtly to the slightest changes in a gas-air mixture. These physical properties are used by the DIP 34A detector for early detection of tanning.
Application area
By and large, the device consists of an LED - a source of infrared radiation and a receiver - a special system of lenses and a photosensitive element. A small air gap between them is all that DIP 34A needs in order to monitor the status of the protected object. The device in question is intended for continuous monitoring of the state of air inside enclosed spaces and issuing 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 make it possible to distinguish between smoke in the room and dust entering the diffuser. Smart signal processing even distinguishes fire smoke from cigarette smoke (negligent smokers are a real scourge of fire systems, the source of 90% of all false positives).
Features and Specifications
You can familiarize yourself with the full characteristics of the DIP 34A device when reading the instructions, here are just some of its distinguishing data:
- An intelligent signal processing system that can distinguish the occurrence of a fire from dusting a room, insects entering the diffuser, and the presence of tobacco smoke in the air;
- the widest temperature range (from 30 degrees of frost to plus 55) makes it possible to use the device both in heated rooms and in unheated;
- extremely small response inertia - not more than 10 seconds;
- a small current consumption in operating mode - about half a milliampere;
- service life of 10 years.
