A typical fire alarm system is not such a simple complex of peculiar technical means that are simply necessary and serve to detect a fire in time, as well as generate control signals intended for fire warning and fire extinguishing systems in automatic mode. It consists of elements such as:

• PKP. Control panel.

• Remote control to control it (if necessary).

• Equipment dedicated to the operator center.

• Fire detectors and various warning devices (signal lamps, sirens, etc.).

Control and receiving devices are designed to power this system. Alarms generated by stand-alone fire detectors generate messages and transmit to the operator center. In addition, alarm signals are generated, after which the control of external systems is triggered (fire extinguishing device, warnings aboutfire, supply and exhaust ventilation, smoke removal).

The control panel, which is equipped with smoke fire detectors, is used to make it easier to control devices that are part of the fire system from a local point of the object. Sometimes without them it is simply impossible to manage such systems. Depending on how they operate, smoke, heat, ionization, light, combined, gas and many other fire detectors can be used.

Types of fire fighting systems:

• Non-address systems. The detectors have a fixed sensitivity threshold. In addition, a group of such detectors is instantly included in the general loop of the alarm system, in which, after the operation of only one of the detectors, a generalized alarm signal will be generated in the loop.

• Address systems. In them, the notice contains information about the address where fire detectors are installed. Thanks to this, it is possible to determine the source of fire with an accuracy of the place where the fire detector is installed.

Sometimes it is necessary not only to find the place of fire, but also to localize this fire in a very short time.

There are more than one type of fire extinguishing systems: powder, water, gas. In order to extinguish a fire caused by electronic equipment, gas extinguishing systems are mainly used. The principle of their operation is based on lowering the oxygen concentration in a closed room usingspraying carbon dioxide and freon. But sometimes this is simply not enough, you have to contact the fire department.

However, fire detectors will always be able to warn that danger is imminent. In this regard, most fire departments recommend installing such warning systems. In any case, fire systems increase the safety of people. That is why they are currently so popular among consumers. They are installed not only in city apartments, but also in houses outside the city. You can also meet them in summer cottages.
