First things first, there are different types of fire sprinkler systems, including dry and wet fire sprinklers. In the case of wet systems, the system discharges water to put out a fire, while a dry system uses pressurized air or nitrogen. In general, fire sprinkler heads contain a certain liquid that can come in different colors and serves an important function.
Knowing what kind of function this liquid has is essential for noticing certain problems with your sprinkler system. This way, you’ll know when to contact specialists offering fire sprinkler service and protect your employees and business in the San Diego area and throughout Southern California.
What is the red liquid in fire sprinklers?
In general, an automatic fire sprinkler system consists of sprinkler heads that have a small ampule or bulb. This bulb contains a colored liquid, which is typically a mixture of water and either glycerin or alcohol. This entire bulb is used to regulate the sensitivity of fire sprinklers, meaning that it activates at a certain temperature and prevents accidental discharge of water.
At a certain temperature, this liquid expands and causes the ampule to break. This will then activate the fire sprinkler system, triggering water discharge in the event of a fire.
As for the red color, it’s added to the liquid to indicate at what temperature the system should activate. Red means that your fire sprinkler will activate at 155° F. Additionally, the color enables you to visually inspect the sprinkler head and identify if the ampule is still in good condition.
Why is fire sprinkler water black?
As we already mentioned, the liquid within the ampule is often colored, which serves a specific purpose. It indicates the temperature at which your sprinkler system will activate. If the liquid is black, it means that you have a high-temperature system that will activate at 440°F.
Here’s an overview of fire sprinkler colors and temperatures:
- Black – 440° F
- Purple – 360° F
- Blue – 286° F
- Green – 200° F
- Yellow – 174° F
- Red – 155° F
- Orange – 135° F
How much water comes out of fire sprinklers?
A great number of individuals believe that fire sprinklers discharge so much water that the damage they cause is far greater than fire damage. However, this is one of the most common misconceptions about fire sprinkler systems.
In fact, each fire sprinkler head activates separately, so not all fire sprinklers will discharge water upon detecting a certain temperature. Only those sprinklers in the area where the temperature reaches the required level will activate and discharge water.
In general, a single sprinkler uses a flow of 15 to 20 gallons of water per minute, while the entire sprinkler uses around 340 gallons to put out a fire. When compared to a fire hose that uses around 150 gallons of water in a single minute, this is definitely not a lot and not enough to cause irreparable damage to your office.
Of course, it’s important to mention that there are different types of fire sprinklers that feature different capacities. This is one of the important considerations to keep in mind when choosing fire sprinklers for your commercial property.
