The fire expander is an element of efficiently operating fire protection systems. These are installations composed of a number of cables, sensors and detectors. Their task is to detect a fire from the very first moments, warn, and often start extinguishing it. These systems are used in industrial facilities, warehouses and IT devices. In such places it is easy to catch fire, and its consequences can be disastrous. Which expander should I choose?

How does a fire system expander work?
The fire expander is an element of the early fire detection and extinguishing system. These are fire extinguishing installations consisting of compatible smoke and elevated temperature detectors, sound alarms, hoses for drawing water from the hydrant and automatic notification systems for emergency services. These types of systems are installed in industrial halls, shopping centers, chemical plants, transhipment warehouses and server rooms. They also increasingly operate in large office buildings and similar places, where numerous computer equipment emit heat and burden electrical cables. Fires caused by short circuits develop quickly and are difficult to extinguish, hence the need to detect and automatically activate fire extinguishing systems as early as possible. Especially since it is impossible to extinguish fires in the above-mentioned facilities using powder fire extinguishers.
How does the expander protect in the event of fire?
Basically, there are passive and active fire protection systems . Passive methods of preventing fire development include fire doors and the use of non-flammable building materials. Active protection includes automatic systems for extinguishing with inert gas, cutting off the oxygen supply to the fire site, and extinguishing with water mist and water taken from a hydrant or from the facility's installation through a system of pipes and wires designed for this purpose. The task of the expander is to regulate the pressure and temperature in these lines, because they expand as a result of water intake. Moreover, a fire is associated with an increase in temperature in the installations, and the expander equalizes the temperature difference between the pipes and the cold water taken in. That is why an efficient expander ensures the proper operation of the fire protection system and enables effective extinguishment, even before the arrival of the fire brigade.
