Nowadays, no security security is complete without special devices. Buy a smoke sensor means to be sure that at the time of the appearance of smoke, the device will notify the approaching danger. The most widespread fire smoke sensors are currently widespread. After all, smoke is the main sign of a flaring fire, and such devices are designed to catch it. The fire detector transmits an alarm to the device of centralized observation, as a result of which a siren is turned on at the facility. The principle of operation of such sensors is as follows: the device is equipped with a special camera with a receiver, as well as an infrared emitter, which is the main link warning about the danger. As soon as the smoke gets into the camera, the penetration of the ik beam to the receiver is difficult. As a result, the IR sensor announces the appearance of smoke in the room. Fire alarm sensors (photo) by type of power such devices are divided into wired and autonomous. They can be either 2 wired or 4 wire. The former are equipped with a sensitive element in the form of an infrared ray, which is radiated by the transmitter with the subsequent processing of the receiver. Autonomous sensors are equipped with built -in siren and food (battery). The controlled area of one warner can reach 1000 kV. m. The area of control of the point fire sensor is 85 square meters. m. Fire alarm sensors are needed to determine the focus of fire with subsequent warning about the fire. Therefore, it is advisable at the facility to install a firewear device, which will allow timely the danger. Many models of sensors are designed for continuous work. Some of them are equipped with two independent sensors that control the state of air near the suspended ceiling and indoors.

This device protects the dwelling from the “fiery invasion”. The original sensor will become a decoration of the apartment, which will observe the situation in the district. Когда появляется дым, срабатывает мощная звуковая сирена, достигающая 90 дБ, при этом происходит частое мигание красного светодиода. In the photo, the art alarm sensor of the artillery and.
