The forward movement of mechanics and electronics, the development of technology could not but affect devices, mechanisms and methods of protecting people and property from fire. Once upon a time, in the reign of John IV, it was progressive to introduce round-the-clock duty on special towers - towers. Such a "warning system" helped to take timely measures and prevent the whole city from burning out from the fire, allowing the destruction of a few buildings to be limited.
Today, electronics play a key role in fire safety. Smart machines are able to not only detect a fire at the earliest stage and report it, but also start extinguishing it.
The "eyes" of any fire system are detectors - devices that directly respond to certain fire factors and generate an appropriate electrical signal. The DIP 34A device has a number of unique technical characteristics that make it possible to increase the efficiency of fire fighting systems by an order of magnitude.automatic systems.
Working principle
The very first detectors used in systems manufactured back in the days of the USSR reacted only to temperature. Soldered with fusible (about 60 ° C) solder, the elastic plates were separated 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 are especially sensitive to the slightest changes in the gas-air mixture. These physical properties are used by the DIP 34A detector for early fire detection.
Scope of application
The device basically consists of a 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 state of the protected object. The device in question is designed to continuously monitor the state of air inside enclosed spaces and issue a signal in case of any changes. By the way, DIP 34A can inform not only about the occurrence of a fire. The characteristics of this detector make it possible to distinguish between smoke in the room and dust entering the diffuser. Smart electronics, when processing a signal, distinguishes even fire smoke from cigarette smoke (careless smokers are a real scourge of fire systems, the source of 90% of allfalse positives).
Features and Specifications
The full characteristics of the DIP 34A device can be found when reading the instructions, here are just some of its distinguishing data:
- an intelligent signal processing system capable of distinguishing the occurrence of a fire from dust in the room, insects entering the diffuser, and the presence of tobacco smoke in the air;
- the widest temperature range (from 30 degrees below zero to plus 55 degrees) makes it possible to use the device both in heated rooms and in unheated ones;
- extremely small response inertia - no more than 10 seconds;
- small current consumption in operating mode - about half a milliamp;
- service life 10 years.
