Are All Fire Sprinkler Heads Interchangeable?

If you’ve ever had a sprinkler head break, you may have wondered if you can just replace it with any old head. The answer is no.

All fire sprinkler heads are not interchangeable. In order to maintain the proper flow rate and water pressure, you need to match the new head to the old one. Make sure your sprinkler system works properly in case of a fire by finding the right replacement head.

What Are the Parts of a Fire Sprinkler Head?

Fire sprinkler head types

The fire sprinkler heads are the part of the fire extinguisher that is most visible. It is usually what is activated in a fire, releasing the water that puts out the fire.

But have you ever wondered what exactly is inside fire sprinklers? Below are some of the parts that make up a typical fire sprinkler head:

Sealing Assembly/Plug: This piece is located at the bottom of the fire sprinkler head, and its purpose is to keep water from entering and damaging the internals of the head. 

Heat-sensitive Activator (glass bulb): The glass bulb sits on top of the sealing assembly/plug and contains a liquid that expands when heated. When the temperature gets high enough, the enlarging liquid breaks the glass bulb and allows water to flow into the deflector. 

Deflector: The deflector forces water out of the fire sprinkler head in a downward spray pattern. 

Frame: The frame holds all the other parts together and also provides a way to attach the head to piping. 

Escutcheon and/or Cover: The escutcheon (a metal ring) or cover (a plastic cover) provides a finished look to the fire sprinkler head and also protects it from damage.

What Is the Flow Rate of a Fire Sprinkler Head?

Pendent fire sprinkler

One of the most important aspects of a fire sprinkler system is the flow rate of the sprinkler heads. This measures how much water is released by the sprinkler head per minute.

Flow rates from residential fire sprinklers range between 13 and 15 gallons per minute, while those from fire hoses range from 95 to 200 gallons per minute. The high pressure from a fire hose can quickly extinguish a fire, but it can also cause significant property damage.

A fire sprinkler system is designed to release moderate water over an extended period, which can help prevent property damage while effectively extinguishing a fire.

How to Choose the Best Fire Sprinkler Heads?

How to Choose the Best Fire Sprinkler Heads

When it comes to choosing fire sprinkler heads, there are a few things you need to consider:

Material of Head

The fire sprinkler heads are generally made of brass or aluminum. Brass is more durable and corrosion-resistant, while aluminum is lighter and less expensive.

Some are made of copper, which is also corrosion-resistant. It is more expensive than brass and aluminum. But it is a better conductor of heat, so it responds quickly to fire.

Coverage Area

The coverage area is the area the sprinkler head can reach with water. Choose a head with a large coverage area so that it can extinguish the fire quickly. The larger the coverage area, the more expensive the head will be.

If you are not sure about the coverage area, you can ask the manufacturer or fire sprinkler installer. Their experts will be able to assist you in choosing the right head.

Type of Head

There are two types of fire sprinkler heads: standard and quick response. Standard heads have a delayed response time, while quick response heads respond quickly to fire.

The other two types are upright and pendants. Pendent heads, also called drop heads, are installed on the ceiling down, while upright heads are mounted on the ceiling up.

Temperature Rating

The temperature rating is the highest temperature the head can withstand before it activates. Glass bulbs have a higher temperature rating than fusible links.

Fusible links are made of metal and have a lower temperature rating. They are cheaper than glass bulbs but are not as reliable. You can determine the temp rating of a head by looking at the manufacturer’s datasheet.

Flow Rate

The flow rate is the amount of water the head can supply per minute. It is essential to choose a head with a high flow rate in order to extinguish the fire as quickly as possible..

If the water pressure is low, you will need a head with a higher flow rate. The flow rate is usually mentioned on the product’s label or in the manufacturer’s datasheet.

Thread Size

The thread size is the diameter of the thread at the end of the head. It is important to choose a head with the correct thread size so it can be installed properly.

The most common thread sizes are 3/4″, 1″, and 1-1/2″. While 3/4″ is the most common size, some heads come with a larger thread size so that they can be installed on thicker pipes. Check your pipe’s diameter to make sure you choose the right head.

Pressure Rating

The pressure rating is the maximum pressure the head can withstand. It can depend on the type of system you have.

If you have a standard gravity system, the head should be able to withstand at least 175 psi. If you have a pre-action pump, its head must withstand 200 psi. And if you have a dry pipe set up, the head should handle 250 psi.

Safety Certification

When choosing a fire sprinkler head, it is important to make sure it is certified by a reputable safety organization. The most common certifications are  FM and UL/CUL.

FM certification means that the head has been tested and approved by Factory Mutual. UL/CUL means the head has passed Underwriters Laboratories.

These are just a few things to remember when choosing fire sprinkler heads. If you have any questions, ask the manufacturer or your fire sprinkler installer. They will be able to help you choose the right head for your needs.

How Does a Fire Sprinkler Head System Work?

How Does a Fire Sprinkler Head System Work

Now that you know a little more about fire sprinkler heads let’s take a look at how they work.

A fire sprinkler system is made up of a series of interconnected pipes that run throughout the building. Each pipe is filled with water under pressure from the municipal water supply. There are also several heat-activated sprinkler heads located throughout the building.

This allows water to flow from the sprinkler head and onto the fire. 57°C/135°F Orange, 68°C/155°F Red, 79°C/174°F Yellow, 93°C/200°F Green, 141°C/286°F Blue, 182°C/360°F Purple are different colors used to identify different temperatures.

When a fire breaks out, the sprinkler head closest to the fire will begin to spray water onto the flames. This will help extinguish the fire and control it until the firefighters arrive.

The sprinkler system is monitored by a sensor located in the sprinkler riser room. If water begins flowing from one or more sprinkler heads, an alarm will go off at the fire panel, notifying the alarm company and the fire department.

Fire departments can then connect to the building’s exterior water supply to provide additional pressure and volume. This will help to extinguish the fire more quickly.

How to Stop a Fire Sprinkler Head?

How to Stop a Fire Sprinkler Head

If you need to stop the flow of water from a fire sprinkler head, there are two methods you can use. First, you can purchase or make sprinkler stops. These are wedges of wood that fit into the head and block water flow.

Alternatively, you can unscrew the sprinkler head and attach fire sprinkler pipes. Both methods will get you wet, so be prepared. Shutoff valves for fire sprinklers are usually hidden in locked rooms or closets, making them difficult to reach.

How Often Should a Fire Sprinkler System Be Inspected?

Most people know that fire sprinkler systems are designed to activate in the event of fire automatically, but what they may not realize is that these systems require regular maintenance in order to function properly.

According to the National Fire Protection Association (NFPA), building owners should inspect sprinkler systems four times a year by experienced fire protection system experts. In addition to these annual inspections, the owner or occupant can conduct monthly and weekly inspections.

While this may seem like a lot of work, it’s important to remember that a working fire sprinkler system could mean the difference between life and death in the event of a fire.

How Long Are Fire Sprinkler Heads Good For?

How Long Are Fire Sprinkler Heads Good For

Typically inspected and maintained fire sprinkler heads have a good life expectancy. That said, fire sprinklers have a limited lifespan and need to be replaced every five years. This may seem daunting, but ensuring that your fire sprinkler system is working correctly is essential.

Luckily, many companies specialize in fire sprinkler maintenance and replacement. By working with a reputable company, you can be sure that your fire sprinkler system will be up to code and can protect your property from fire.

Do Fire Sprinkler Heads Detect Smoke?

Surprisingly, the answer is no. Fire sprinkler heads are designed to activate when they reach a certain temperature. So if the smoke from a fire is hot enough, it could trigger the sprinkler head to discharge.

Only heat can tell the sprinkler head if smoke is present, not the smoke itself. Some sprinklers use smoke detectors to trigger water flooding them through solenoids.

But even in these cases, water still needs heat to discharge from the sprinkler head. So while smoke detectors can be an essential part of a fire safety system, they alone will not activate a fire sprinkler head.

Why Install a Fire Sprinkler System?

Why Install a Fire Sprinkler System

A fire sprinkler system is one of the essential safety equipment in a home. In the event of a fire, the sprinkler heads will activate and help to extinguish the flames. This can minimize property damage and, more importantly, help to save lives.

It is important to remember that fire sprinkler systems must be installed appropriately to be effective. It is therefore important to use the best fire sprinkler heads and have them installed by a professional.

When done correctly, a fire sprinkler system can provide peace of mind in knowing that your home is better protected against the threat of fire.
