Why Choose a Firefighter Safety Switch? What is the Function of the Firefighter Safety Switch?

        In the solar photovoltaic industry, there are major problems in the safety of fire extinguishing in buildings installed with solar photovoltaic systems. During the day, when solar panels generate direct current, it is necessary to quickly and safely isolate the photovoltaic panels from the rest of the system in the event of a fire. The Firefighter Safety Switch disconnects the DC cable from the voltage source and extinguishes the fire when there is no electrical hazard.

        The Firefighter Safety Switch provides maximum safety for firefighters who have installed solar photovoltaic systems. It works by disconnecting the photovoltaic panel from the rest of the system once the main AC circuit breaker trips or is switched by the firefighter. This is achieved by the inherent undervoltage release, which will automatically disconnect when the AC voltage is not present.

1. AC Power manually shut down

        The first step for any firefighter to put out a fire is to turn off the main AC power circuit. In this way, the actual fire can be extinguished without the risk of electric shock. Slocable has developed a Firefighter Safety Switch based on this standard international safety program. This prevents firefighters from taking any additional actions in the event of a fire, thereby maximizing their and your safety in the event of a fire.

2. Automatic DC Power Shut Down

        Once the firefighter shuts down the main AC circuit, the SRS will detect this. If this power failure continues, it will automatically switch to the OFF position within 5 seconds. Since the SRS is close to the photovoltaic module, the high-voltage DC current from the photovoltaic module will be completely isolated, which provides a safe environment for firefighters to extinguish a fire indoors.
