A fire protection switch is an element that helps ensure the safety of facilities where electrical installations operate. In the event of a fire, it is very important to cut off the power source, except for the power supply to fire equipment and installations important for controlling the threat situation. In what situations should a switch be installed and what is its correct location?

Fire protection power switch installation location
According to fire safety regulations, certain categories of buildings are required to have power switches installed. These allow the power supply to be quickly cut off in a dangerous situation, such as when a fire breaks out, to limit the risk of it spreading.
A fire switch is an element that can be installed where safety is most important. In houses and apartments, e.g. in the kitchen or garage, technical room. Often, these elements are also installed in places such as: public buildings, e.g. shops, offices, hospitals and industrial facilities. They are placed in the main switchboards. Especially in factories, industrial and production halls. Additionally, properly matched protection must be found in various special installations. This term refers to installations with a particularly high fire risk.
The installation of a fire power switch should be carried out in accordance with applicable regulations. The device must be located in a publicly accessible place so that it can be easily used in an emergency. It is most often placed near the main entrance. In the case of a building with more than one entrance, a fire power switch must be located at each of them.
What is a CNBOP certified fire protection circuit breaker?
CNBOP is a certificate issued by the Central Fire Protection Laboratory. It is issued to products that have undergone restrictive tests and then approved as meeting the safety requirements that buildings should meet. Products that have received a certification certificate meet the highest safety criteria. The certificate confirms the compliance of the tested product with the applicable safety standards.
In the case of PWP fire safety switches, the following aspects are checked before issuing a certificate:
- fire resistance and structural strength in a fire situation;
- safety of installation and use;
- product compliance with applicable fire safety regulations and standards.
A strict evaluation of the device by the CNBOP Laboratory and obtaining an appropriate certificate of conformity guarantees that the selected product guarantees reliability and effectiveness.
Fire switch connection diagram
In order for the PWP fire protection current switch to function properly, it must be connected correctly. The set of instructions placed by the manufacturer on the packaging or in a special description should be carefully followed so that the whole ensures safe use. Depending on the model, the selected variants may require taking into account specific guidelines.

As a rule, the switch is equipped with connectors that allow for the connection of power circuits and fire detectors. In models approved for use, there are additionally two diodes in green and red. When installing the switch, remember that the red diode should indicate normal operation when the device is connected to the mains.
When the green light is on, it means that the button has been turned on and the electricity supply in the facility has been cut off. The power connection diagram for fire protection devices specifies the method of installing the device and the selection of electrical cables. The manufacturer's instructions should always be followed, because only then will the protective function be maintained. In public utility facilities, the installation and inspection of the correct operation of the switch is the responsibility of the administration.
When is a fire safety switch required?
The rules governing the installation of the PWP fire protection current switch are specified in the law on fire protection of buildings. An important issue is that the device must have the appropriate certificates for approval for use. The currently applicable regulations are:
Regulation of the Minister of Infrastructure and Construction of 17 November 2016 on the method of declaring the performance of construction products and the method of marking them with a construction mark and Regulation of the Minister of Development, Labour and Technology of 4 December 2020 amending the regulation of 17 November 2016 on the method of declaring the performance of construction products and the method of marking them with a construction mark.
Installing appropriate protection is mandatory in some situations. An example would be a photovoltaic fire switch , because any installation above 6.5 kW must be properly protected.
Power supply disconnection must also be used in fire zones with a volume greater than 1000 m3, and explosion hazard zones also require special protection. Controlling the protection system in the case of switches is simple and intuitive.
Fire protection power switches at the Onninen wholesaler
At Onninen electrical wholesaler we have a wide range of switches that will help to effectively ensure the safety of installations, buildings and therefore the people inside them.
One of the most frequently chosen solutions are SPAMEL PWP1-W01-A-11-2LED7/M fire protection power switches . This is a manual button that allows you to quickly disconnect the power in the entire facility when there is a risk of fire. Its task is to disconnect all installations, except those that are necessary for the proper functioning of systems used during rescue and firefighting operations. The button panel has two diodes - green and red. The first one indicates that the button has been activated, and the second one - the supervision state. This model has all the necessary certificates confirming the safety of use.
In the Onninen wholesaler we also have other versions of fire switches, such as the EATON 30A, MC4 PV fire switch . This model is equipped with an optional voltage release, with a frontal protection class of IP 65 and is designed for mounting on a board. Simple to use and easy to install, in practice it provides effective property protection.
A special variant are switches dedicated to solar installations, such as the EATON 2R M22-SOL-PVT45PMPI02Q 150645 PV fire button . The generation of electricity in photovoltaic panels creates a special zone that must be protected in a special way. In accordance with the applicable regulations on technical conditions, the use of an installation whose power is greater than 6.5 kW must be equipped with an appropriate safety switch to avoid damage.
