The lock shield valves are installed usually in the fire hose reel and the valve can be opened only by the key. and the key shall be kept with the maintenace team not in the valve. So the valve cannot be closed by the other people.
The fire main isolation valve is a critical component in a fire protection system, designed to control the flow of water within the fire main network. Its primary purpose is to isolate sections of the fire main for maintenance, repair, or during emergencies without disrupting the entire system. By allowing for targeted control, it helps ensure the reliability and effectiveness of fire suppression efforts while maintaining safety for personnel and property.

There is evidence that the Egyptians (yes, those nice folks who built the pyramids) and the Romans, both cultures of the ancient world, had organized fire fighting groups. That makes fire fighting a very old tradition as well as an essential public service. Use the link below to read more.
The FM-200 system is a clean agent fire suppression solution widely used to protect sensitive areas like server rooms, data centers, and electrical equipment. It works by quickly releasing a chemical gas that suppresses fire without leaving any residue, so it won’t damage electronics or documents. FM-200 is safe for occupied spaces when used correctly, as it extinguishes flames by removing heat and interrupting the chemical reaction of fire. The system is fast-acting, environmentally friendly, and requires minimal cleanup, making it a preferred choice for critical facilities where water-based sprinklers could cause serious damage.
Normally it is filled with compressed air. A dry sprinkler system is used in areas exposed to temperatures that would freeze water. When a fire is sensed the soft metal link of a sprinkler head melts , releases the compressed air which in turn opens a valve to a fire main allowing the system to flood with water and extinguish the fire. Parking ramps in the northern US have dry systems, for example, because of the weather.

It's type of valve used in fire water system for fire protaction.
A sprinkler bell valve in a fire protection system controls the flow of water to sprinkler heads. It opens when the system detects a fire, allowing water to flow and extinguish the fire.
The function of a sprinkler pressure valve in a fire protection system is to regulate and control the water pressure within the system to ensure that the sprinklers operate effectively in case of a fire.

we have to distinguish between firefighting and fire alarm system. fire fighting is mechanical work (either sprinkler system or Foam or CO2 or FM200) and there is fire alarm or detection system this is an electrical thing that includes ( detectors an fire alarm system) for electrical control building we use FM200.
Yes, fire sprinkler systems often have a bypass valve, which allows for maintenance or testing of the system without disrupting water flow to the sprinklers. This valve enables technicians to isolate certain sections of the system while ensuring that others remain operational. It is essential for ensuring the reliability and functionality of the fire protection system during routine checks or repairs. Proper installation and maintenance of the bypass valve are crucial for overall system effectiveness.
Fighting Fire with Fire was created in 1991.
deluge valve work from close position to open position to release the material to shut off the fire once it receive a signal from fire detector, installed in a system.
The Inspector's Test Valve in a fire sprinkler system is designed to facilitate routine testing and inspection of the system's water flow and pressure. It allows for the simulation of a fire event by enabling a controlled discharge of water, which helps ensure that the system is functioning properly. Additionally, it aids in verifying that the alarm system is operational, providing essential data for maintenance and compliance with safety regulations. Regular testing through this valve helps to identify any issues before they become critical.
On a ship certain decks/areas are assigned fire zones to aid in firefighting if such an event occurs. Additionally it helps the crew locate the fire use the internal fire fighting system (if available) such as a C02 extinguisher system to put out the fire.
The kinetic energy of the water is being converted into pressure energy and thus pressurised water kept in pipeline in fire fighting system.
