Our Most Asked Questions About Fire Sprinkler Systems
what the costs of installation of a fire sprinkler system in Australia in 2022?
Fire sprinkler systems are a necessity in Australia, with fire safety rules requiring installation in buildings built after 1 January 2013. This means that there is a large number of buildings that need to be retrofitted with fire sprinkler systems.
Looking at the high costs of installing these systems, it’s understandable why many business owners are hesitant to invest in them. It can take up to $2800 or more per square meter (or 100 sq ft) to install a fire sprinkler system on every floor of a building.
The first step to deciding if you should install a fire sprinkler system is determining how much each square meter will cost you. Here is a breakdown of what each component costs:
Sprinklers cost $150 per square meter for commercial products and $300 for industrial-grade sprinklers
Riser pipes cost $55 per square meter
Ducting and connections cost $30 per square meter for wet pipe systems, and $55 per square meter for dry pipe systems
Damage from water leakage can cost thousands of dollars, and even more if your employees or customers get hurt by the water. But it’s possible to avoid these significant costs by installing a fire sprinkler system on your own.
Are fire sprinkler systems effective for electrical fires?
“Electrical fires” are not really what most people understand. They are thinking electricity is ‘burning’ and needs to be extinguished.
Typically, an electrical short or overheating of the wires or electrically-powered device (because of overloading) is the incipient cause of an “electrical fire.”
But, as soon as the electrical source/flow is stopped – a wire disconnects, a breaker pops, etc. – it is no longer an ‘electrical fire.’ Ergo, most ‘electrical fires’ are actually Class A – conventional wood, paper, etc.; or Class B – POL (petroleum, oil, lubricant) fires.
Stated another way – if there is no active circuit – flow of electricity to the site of the burning – it is no longer an ‘electrical fire.’
So, the sprinkler connection is this. Sprinklers are ineffective if/when used on charged (hot) electrical circuits – in fact they’re dangerous. The only ‘advantage’ to them is that they might promote a short circuit and tripping of the power-source breaker.
But once the inflow of electricity is stopped, sprinklers can be hugely effective on the resulting/remaining Class A fire. Class B is a bit different, as the inflow of water could cause the spread of fire as it floats on the water.
What are the best pipeline system for fire sprinkler?
The fire sprinkler industry is becoming more complex, and thus requires a system that can adapt to changing demands. The most successful systems for fire sprinkler companies are ones that can be customized to meet individual company goals and needs.
All fire sprinkler systems should be considered as a pipeline system, since they are all designed to transport water from one location to another. These water transport systems need to accomplish two basic goals: delivering the correct amount of water to the desired area, at the right time, and in a consistent manner. Ideally, they do this while using the least amount of water possible.
The best way to accomplish these goals is by using an automated fire sprinkler system that features an advanced control panel. An automatic control panel allows for water pressure adjustments, and can help ensure that no water is wasted when it’s not necessary. This helps reduce unnecessary waste and makes sure more water gets where it needs to go.
Key components of an effective pipeline system include:
What type of pipe is used for fire sprinkler systems?
In Australia, the fire sprinkler system uses a special kind of pipe called fire sprinkler pipe. Fire sprinkler pipe is made of polymer-coated steel, so it’s lightweight and easy to work with. It’s also impact-resistant, which makes it perfect for the hostile environments that it comes into contact with in a fire sprinkler system. The pipe is made in a helix-like pattern, so that when the water just a little bit of water comes through the pipe, it can cool off and be slowed down before it hits the floor. This helps to prevent damage to electronics, wiring, and other elements that might be in the area.
Fire sprinklers are made up of two parts: one part that is on the ceiling/wall and one part that is attached to a pipe in the ceiling/wall. The part on the ceiling/wall is called an orifice, while the part attached to the pipe is called a head. The orifice fits over an opening at the end of what’s known as a coupling nut, which secures the orifice to the ceiling/wall. The coupling nut then connects to another coupling nut on what’s known as an outlet fitting. The outlet fitting has threads on top to attach it to another outlet fitting
Are fire sprinkler systems pressurized?
There are two basic types of fire sprinkler systems. The first is the wet system. A wet system has water in it under pressure all the time. When a sprinkler head is broken, the water flows through it. The advantage to this system is that the water is delivered more quickly, and only the heads that have been affected by high heat will open up. Thus there is less water damage done.
In a dry system, there isn’t any water in it at all. Dry systems are dry! But when a fire sets off the alarm, a pump gets started that fills the sprinkler risers and lines with water. The sprinkler heads aren’t sealed, so every line that water flows into will cause water to spill out onto the floor regardless whether there was ever a fire there or not. There can potentially be severe water damage to locations that were never endangered by fire.
How do you service a fire sprinkler system?
In Australia, the standard of fire safety equipment is determined by AS1851- 2012 This standard sets out a number of procedures that need to be followed when servicing fire sprinkler systems. In order to ensure the best and most effective care for your fire sprinkler system, it is important to follow these procedures closely.
The most basic way to service your fire sprinkler system is by having an expert check and ensure the system is working properly. Every month, they will inspect it again, making sure all the parts and components are in proper working condition. They will also make sure that the water levels and pressure are adequate, as well as check if staffing needs to be increased for your business.
The following are some more detailed ways you can have your fire sprinkler system serviced:
Check the piping for leaks and other issues
Check for potential problems with the fuses, valves, and gauges. If any of these components have been damaged, you will need to replace them immediately
Check if there is any rust or corrosion on the sprinklers themselves. Rust or corrosion can cause damage to the sprinklers if left unchecked
Inspect the alarm system that activates when there’s a problem with the sprinklers. If any part of this mechanism has been damaged or broken, you will need to replace it before you can continue using it
Make sure there hasn’t been any vandalism done to your fire sprinkler system. While it may seem like a harmless prank, it could lead to serious problems if not handled correctly
What is the difference between a fire suppression system vs. a fire sprinkler system?
There are a number of differences between fire suppression systems and fire sprinkler systems, but the most important one is that fire suppression systems use gaseous agents to extinguish fires.
Both kinds of system are designed to identify a fire and take action to put it out without the intervention of first responders. Fire sprinkler systems do this by spraying water on the site of a fire from pipes that run throughout a building. Fire suppression systems, on the other hand, use a variety of gaseous agents, including nitrogen gas and carbon dioxide, which are typically stored as liquids and then released as gases when they are needed.
Fire sprinkler systems work best in areas where there is little risk of electrical shock or where water damage is not an issue. They are also best suited to fires caused by burning materials such as paper and cloth. Fires caused by flammable liquids are harder to put out with water, because they can just keep burning in puddles of water. This type of fire is better put out with gaseous agents.
What is a fire drencher/deluge system?
A fire drencher system is a specialized type of sprinkler head designed to extinguish fires in seconds. A fire drencher system is also known as a “water curtain,” and it consists of a long pipe attached to a sprinkler head. The pipe is filled with water, and the sprinkler head operates much like a regular one, except that instead of dispersing water over the surrounding area, it releases a column of pressurized water directly above the fire.
The advantages of using a fire drencher system over other types of fire-fighting systems are that it’s easier to install and maintain than traditional sprinklers, works in any environment (including areas such as warehouses, where regular sprinklers would freeze), and can be used with both water and foam-based extinguishing agents.
A common misconception about the fire drencher system is that you need to have lots of water pressure in order for it to operate; this isn’t true, as the pressure comes from the force of gravity alone.
What is the function of the tamper switch in a fire sprinkler system?
A fire sprinkler system tamper switch has a number of different functions, depending on the type of system in place. The primary purpose of the tamper switch is to prevent accidental or malicious activation of the fire suppression system. A fire sprinkler system tamper switch will generally consist of a physical barrier that blocks access to the control panel or valve. Additionally, some systems will have an electrical barrier that shuts down the entire system when the switch is overridden or tampered with.
All fire suppression systems are required by law to have a tamper switch installed to prevent accidental discharge caused by children or other unsupervised individuals who may come in contact with an improperly secured control panel or idle sprinkler head and accidentally activate the system.
Can a fire sprinkler go off without an actual fire?
Yes, a fire sprinkler can go off without an actual fire. This is called a false alarm and it happens when the sprinkler system malfunctions due to maintenance issues or other problems. While this may seem like a minor inconvenience, false alarms cost businesses millions of dollars each year in damage and lost productivity.
What kind of pumps are most commonly used for fire sprinkler systems?
The majority of fire sprinkler systems are designed to use centrifugal pumps. Centrifugal pumps use an impeller with vanes that rotate at high speeds to push water through the system, and are often driven by electric motors. These pumps are able to move a large amount of water at a very fast rate and can be used for both low-pressure and high-pressure applications. The primary advantage of centrifugal pumps is that they do not require any priming or pre-filtration, making them easy to install and maintain.
How does a jockey fire pump work?
A fire sprinkler system contains a lot of pipes and valves to control the flow of water. For example, each sprinkler head has a valve that can turn it on or off. But sometimes, valves just aren’t enough. Sometimes you need a jockey pump.
Jockey pumps are used when the volume of water needs to be precisely controlled, such as when you’re filling a bathtub or swimming pool. In a fire sprinkler system, they’re often paired with other devices so that if one component fails, another component will still keep the system working correctly.
Many people think that jockey pumps are located in the same room as fire sprinklers and valves, but this isn’t true: They’re located in an entirely different room to reduce the risk of them being contaminated by airborne particles from fires.
How often should I have a pump inspection for a fire sprinkler system?
For pump inspections, you should keep up with Australian Standards.
In Australia, the Australian Standard for the Installation and Servicing of Fire Protection Systems and Equipment is AS1851-2012. This standard recommends that all fire protection systems be inspected at least once every six months, with a more thorough inspection occurring annually.
However, some systems, such as those that utilize pumps, require more frequent inspections. These inspections can be done by a competent person onsite, or they can be performed by a qualified inspector.
The standard you’re looking for is AS 2118.5-2007 Automatic fire sprinkler systems – Part 5: Pump systems for fire-fighting services. According to that standard, all centrifugal pumps used in fire sprinkler systems should be inspected and tested within 6 months of installation at a minimum. Once that initial inspection has been done, pump inspections should be done every 6 months according to this standard. More frequent inspections may be required depending on your specific circumstances.
