Smoke detectors are devices designed to detect a fire in a room. From a technical point of view, it is more correct to talk about fire detectors, since as a result of combustion, gas and flames are also formed.
In our review, we will provide recommendations on what to look for in order not to make a mistake when choosing which company is better to buy a product, we will give a description of popular models, and determine average prices.

The design can be analog (shows the level of the measured value, its concentration formed during a fire) or digital (they detect the presence of smoke, but cannot determine the level). There are 3 types of systems:
Inside buildings, a fire detection system detects the presence of danger, through detectors, activates the necessary alarms for appropriate action. In addition to automatic systems, there are manual emergency buttons (IPR). The most commonly used detectors are described below, based on various physical principles of operation, consider what they are:
Depending on the type of room, the criteria for choosing a detector change, products with different design features are purchased, some of them are more sensitive to pollution and can lead to false alarms.
The best technological solution available today is a system using impulse or jet fans to ensure efficient operation in the event of a fire. Axial, centrifugal models are placed along the perimeter of the site. They distribute fresh air while carrying away any pollution or smoke.
For flat ceilings, without obstructions, the distance between the detectors should not exceed 9 m. Considering that protected areas are square or rectangular in shape, a sensor located in the center of the room will cover an area with a diameter of 13 m.In practice, there are ceilings of different levels, protruding beams, partitions that prevent the passage of smoke in the direction of the sensors. Then the distance between the devices should vary, the multi-point principle of placement is applied.
In order for the detector to be 100% effective, the maximum height must be no more than 3 m. The performance of a sensor placed on a 6-meter ceiling must be multiplied by 0.64, which reduces the distance between the detectors. The distance from the unit to the wall must be at least 0.5 m, they should be placed as close as possible to the center of the room, since more smoke and heat accumulate in this area. Avoid installing detectors:
Temperature sensors and gas detectors are installed in rooms where smoke is generated (garages, kitchens). Manual notification buttons (MP) are placed in such a way that they can be easily found visually at emergency exits. The location of the alarm should correspond to the physical zone of the fire in order to quickly identify the place from which it was activated.
It is necessary to take into account the most likely development of a fire at its initial stage, the height of the ceiling, environmental conditions and all possible sources of false alarms within the protected areas. The number and location of the detectors depends on their type, the geometry of the protected area and the environment in the controlled area. The choice of product is based on two main assumptions:
As a rule, you can install the kit at home or work by contacting a security company. Professionals will offer the unit best suited to your needs. Important elements of the fire system:
Having a fire alarm at home is not required, but desirable. Depending on the type of room, one or another type of product may be useful. In hazardous industries, it is better to install linear explosion-proof models made of durable materials.
Inexpensive new items can be purchased from companies involved in the trade of security systems. Managers will tell you about the best manufacturers, the popularity of models, how much they cost. Employees will provide: advice on the use of product functions; step-by-step instructions on how to install the detector yourself at home. The battery-powered budget detector can be ordered online in the online store.
