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

Place of installation of the fire protection switch
Pursuant to fire safety regulations, certain categories of buildings require the installation of power switches. Thanks to them, the power supply can be quickly cut off in an emergency situation, e.g. when a fire breaks out, to limit the risk of its spread.
A fire extinguisher is an element that can be installed where safety is paramount. 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 included in various special installations. This term refers to installations with a particularly high fire risk.
The fire protection switch should be installed 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 situation. Most often it is placed near the main entrance. In the case of a building with more than one entrance , a fire protection switch must be located at each of them.
What is a CNBOP-certified fire protection switch?
CNBOP is a certificate issued by the Central Fire Protection Laboratory. It is issued to products that have been subjected to strict 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 applicable safety standards.
In the case of PWP fire safety switches, the following aspects are checked before issuing the certificate:
- fire resistance, as well as structural strength in the event of a fire;
- safety of installation and use;
- product compliance with applicable fire regulations and standards.
A strict assessment 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
For the PWP fire protection switch to work properly, it must be properly connected. The set of instructions provided by the manufacturer on the packaging or in a special description should be carefully followed to ensure safe use. Depending on the model, the selected variants may require specific guidelines to be taken into account.

As a rule, the switch is equipped with connectors allowing the connection of power supply circuits and fire detectors. The approved models also have two green and red diodes. When installing the switch, remember that the red diode should indicate normal operation when the device is connected to the electrical network.
When the green light is on, it means that the button has been turned on and the electricity supply to the facility has been cut off. The power supply connection diagram for fire-fighting devices determines the method of mounting the device and the selection of electrical cables. Always follow the manufacturer's instructions, as only then will the protective function be maintained. In public buildings, installation and control of the proper operation of the switch is the responsibility of the administration.
When is a fire protection switch required?
The rules governing the installation of the PWP fire protection switch are specified in the law on fire protection of buildings. An important issue is that the device must have appropriate certificates to be approved for use. The currently applicable regulations are:
Regulation of the Minister of Infrastructure and Construction of November 17, 2016 on the method of declaring the performance properties of construction products and the method of marking them with a construction mark and the Regulation of the Minister of Development, Labor and Technology of December 4, 2020 amending the regulation of November 17, 2016 on the method of declaring the performance properties of construction products and the method of marking them with a construction mark.
Installing appropriate protection is obligatory in some situations. An example would be a photovoltaic fire protection switch , because every installation above 6.5 kW must be properly protected.
Switching off the power supply must also be used in fire zones whose volume is larger than 1000 m3, and explosion hazard zones also require special protection. Controlling the protection system for circuit breakers is simple and intuitive.
Fire protection switches at the Onninen wholesaler
At the Onninen electrical wholesaler , we have a wide range of switches that will help 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 switches . This is a manual button that allows you to quickly disconnect electricity to the entire facility when there is a risk of fire. Its task is to disconnect all installations, except those necessary for the proper functioning of systems used during rescue and fire-fighting operations. There are two diodes in the button panel - green and red. The first one indicates that the button has been activated, and the second one indicates the supervision status. This model has all the necessary certificates confirming its safe use.
In the Onninen wholesaler, we also have other variants of fire protection switches, such as the EATON 30A, MC4 fire protection switch for PV . This model, equipped with an optional shunt release, with a frontal protection class of IP 65, is intended for mounting on a board. Simple to use and easy to install, in practice it provides effective protection of property.
A special variant are switches dedicated to solar installations, such as the EATON 2R M22-SOL-PVT45PMPI02Q 150645 PV fire protection button . Generating electricity in photovoltaic panels creates a special zone that must be particularly protected. 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.
