Fire protection systems are part of your building’s safety plan. It’s your job as a building manager to fulfill these plans without cutting corners. It doesn’t matter what kind of facility you have, it’s important that you place this protection system in your building. You can protect the lives of those inside your building during emergencies. Fire protection systems are also designed to protect the building. If you’re not knowledgeable about different types of fire protection systems, scroll down to learn more about them.


Wet Fire Sprinkler System

Wet Fire Sprinkler System

Wet pipe systems are connected to overhead sprinkler piping that’s filled with water under pressure. When a fire causes one of the connected sprinklers to activate, water is immediately discharged from the sprinkler head. It’s usually the heat of the fire that activates this system, not the smoke. Wet fire sprinkler systems are the most common and simplest of the fire protection systems. These are reliable and it tends to be much easier to install and maintain. As your first choice, sprinkler systems like these can be easy to work with, easily modified, and can be your building’s main lifeline.

Unfortunately, the wet sprinkler system can’t be used in all environments. You cannot install this system in environments where temperatures reach below 4 degrees Celsius. You could also damage your property significantly because of accidental leaks and malfunctions caused by faulty piping. It’s recommended that you avoid installing wet fire sprinkler systems in areas with sensitive equipment and documents to avoid property damage.


Dry Pipe Systems

Dry pipe systems are much different from your typical wet fire sprinkler systems. These systems don’t have water in the piping. Instead, the system uses pressurized air or nitrogen to suppress the fire. The pressurized air will hold back the water supply at the main dry-pipe valve. When a fire is detected and the sprinkler activates, the air pressure significantly drops and the main dry-pipe system valve releases water into the piping system to discharge water from the sprinklers.

If you have a freezing environment, dry pipe systems are a perfect choice. These systems are designed to work well in walk-in refrigerators, warehouses, and loading docks. The special air pressure requires a lot of attention as it’s much more complex than wet fire sprinkler systems. It’s also much more expensive and requires a lot of maintenance.

The fact that water needs to travel from the piping and sprinklers, there can be a delay of 60 seconds. Dry pipe systems also have design restrictions which makes it hard to upgrade or modify the system. However, if you have areas with freezing temperatures and important documents or equipment, you can install this with the regular wet fire sprinkler system for total coverage.


Special Hazard Fire Protection Systems

Special fire hazards can happen at any time and anywhere. A special fire hazard can be in your building, in a specific room or piece of equipment. This can be your data center, power generators, manufacturing, healthcare, and telecommunications. These areas can be sensitive to fire and hard to manage with ordinary systems. The systems mentioned above may not be suitable for controlling and suppressing fire in these areas. That’s why special hazard fire protection systems are created.

Your line of defense in these sensitive areas starts with your special hazard fire protection system. These are designed to quickly detect fire and heat. It’s designed to work where sprinklers can in order to protect your building occupants and prevent business interruptions. If you’re afraid to lose assets, information, and revenue, this is the system you need. Luckily, there are trained, qualified personnel that can help you design, install, service, and maintains your special hazard fire system. This system makes use of chemical agents such as inert gases, water mist, foam, and dry chemicals.


Dry Chemical Fire Suppression Systems

For industrial settings, dry chemical fire suppression systems are used when water is inaccessible. Dry chemical systems use different dry chemical compounds to extinguish the fire when there’s no water. These systems are rechargeable and can be easily installed in many commercial and industrial settings. It’s easy to access and efficient to use if you have no other means of fire suppression. These are nonconductive and can be used to suppress ordinary fires but also liquid fires when it involves live electric equipment.


Key Takeaway

There’s a slim chance that you’ll encounter a fire. But when you do, it’s important to have all the safety measures ready when it happens. There are so many types of fire protection systems out there and they all offer a wide variety and scope of protection for different types of situations.

Choosing the right system depends on the type of institution and the requirements you have. If you want to protect the integrity of your building and prevent any accidents, installing a fire protection system can increase the chances of survival for your employees in case of emergencies.
