Commercial Fire Protection

Best Fire Sprinkler Contractors in Raleigh

Fire sprinkler systems are a key component of most commercial Fire Protection protocols. They have been effective in fighting fires since the 1800s. The Center for Disease Control and Prevention (CDC) and National Fire Protection Agency (NFPA) reference many studies that conclude that civilian fire death and injury rates are lower when fire sprinklers are present in buildings where fires break out.

The concept of how fire sprinkler systems work is quite easy to understand. A sprinkler head is hooked up to a water system and when smoke or fire is detected they activate to suppress the fire. Simple as that may sound, it still requires the right fire sprinkler technician to install it correctly. Raleigh Fire Protection Services’s fire sprinkler contractors are trained and certified experts in the installation, maintenance, and repair of fire alarm systems.

Types of Fire Sprinkler Systems

Designing a fire sprinkler system starts by determining what kind of fire sprinkler system should be installed. NFPA 13, standard for the installation of sprinkler systems, lists the types of sprinkler systems that are acceptable for use in commercial buildings today. Acceptable sprinkler systems include, wet, dry, pre-action, and deluge.

Wet Pipe Sprinkler Systems
This is the most common type of sprinkler system, because it is effective and affordable. The term “wet pipe” refers to the piping that is connected to the sprinkler being constantly filled with water or pressurized with water. Sprinklers that are located on the ceiling have a glass bulb or fusible link in them. Once the heat near that sprinkler head gets hot enough, the bulb or link breaks, and water free flows out of the sprinkler head immediately. There are some important considerations as to whether wet pipe sprinkler systems are the best fit for the application you are considering. For  example, wet pip sprinkler systems can only 

be installed in places where the temperature is going to be 40°Fahrenheit or greater. Otherwise the system pipes can burst in the water freezing inside of them. There are other options that are discussed next that may be better if there is a risk of water in the pipes freezing.

Dry Pipe Sprinkler Systems
A key difference between a dry pipe and a wet pipe sprinkler system is that dry pipes are not constantly filled with water. Just like with a wet pipe system, the sprinkler heads of a dry pipe system have a fusible link or a glass bulb that breaks when the temperature at the ceiling reaches a certain temperature. Except with a dry pipe system, the water does not immediately disperse on flames because it has to travel from where it is being released. When the glass bulb breaks, the sprinkler head opens, and air is released. This drops the pressure in the pipes and opens the valve to allow water to fill the sprinkler system. Dry pipe systems are great options where freezing temperatures may impact sprinklers systems.

Preaction Fire Sprinkler Systems
This is the most complicated sprinkler system. There are three different types of preaction sprinklers: non-interlock, single interlock and double interlock. The main difference between preaction sprinkler systems and dry and wet pipe sprinklers is that activation of a preaction sprinkler is predicated on some other type of device that triggers the system. An example would be a heat detection system that triggers the sprinklers system to activate and fill with water. The benefit of preaction systems is that they don’t activate if there is an accident that breaks the glass bulb or linkable fuse; the system will not fill with water and go off because the other detection condition (high heat detection) has not been met.

Deluge Fire Sprinkler Systems
Deluge systems are most-like preaction systems. The primary difference is that the system uses open sprinkler heads. This means that once the water fills the deluge system, it will flow out of all the sprinkler heads. Deluge sprinkler systems still rely on a detection system that need to be activated in order for the system to fill with water.
