Fire sprinkler systems save lives, protect property, and safeguard buildings from damage. They’re a key part of any fire prevention program, and they’re also required by law.
In Los Angeles, most business owners are required to install and maintain a fire sprinkler system in full compliance with the LA fire code. Unfortunately, understanding the commercial fire sprinkler requirements can be difficult.
This article breaks down exactly what users need to do to follow the LA fire sprinkler city codes and keep occupants safe in case of a fire.
Commercial Fire Sprinkler Requirements in LA
The LA Fire Sprinkler City Codes require building owners to install and maintain automatic fire sprinkler systems in certain buildings:
- Automatic fire sprinkler systems must be installed in existing residential dwellings.
- New residential buildings must have automatic fire sprinkler systems installed, regardless of the building’s size.
- Commercial high rises must have automatic fire sprinkler systems installed.
- New commercial structures must have automatic fire sprinkler systems installed, provided the structure has a fire area greater than 5,000 square feet.
Commercial Buildings
The majority of commercial buildings must have fire sprinklers installed. However, there are some exceptions. Some smaller commercial buildings are exempt from the requirement. In some cases, historical buildings are also exempt from the rule.
When in doubt, it’s a good idea to consult with the experts. Violating the fire code can result in hefty penalties, so it’s a good practice to exercise caution.
The right Fire Sprinkler System
There are four main kinds of fire sprinkler systems: wet pipe, dry pipe, pre-action, and deluge. Most commercial facilities use the wet pipe system, but depending on the situation, a different type of fire sprinkler may work better for users.
Kord’s highly trained technicians will inspect the facility and design a system to meet the needs so users can stay safe and compliant, without users having to overspend their budget.
Here are the four types of fire sprinkler systems:
Wet Pipe Sprinkler System
This is the most common sprinkler system in modern facilities. The pipes in this system have constant access to water, so that as soon as a fire starts, the pipes — already filled with water — can activate and spray the fire immediately.
The sprinkler heads in this system are covered with glass bulbs. In the event of a fire, the rising temperature shatters those glass bulbs so that water sprays out of the sprinkler heads. This ensures a quick response to fire. Only the sprinkler heads near the fire are activated, so it also minimizes water damage.
Dry Pipe Sprinkler System
Dry pipe systems are used in buildings in colder regions, where pipes might freeze at certain times of year.
In a dry pipe system, the pipes are not constantly filled with water. Instead, they are filled with pressurized air. When a fire occurs, the air pressure drops, allowing a valve in the pipes to open and let water flow in. The sprinkler heads then spray water, putting out the fire.
Pre-Action Sprinkler System
Pre-action sprinkler systems are highly complex. They are mainly used in settings where it’s important to avoid water damage and where it could be devastating to have the sprinklers go off unnecessarily.
They require specific triggers, like an external smoke detector, to open the valve that releases water to the sprinkler heads. There are a few different types of pre-action sprinkler systems, each with a different trigger for releasing the water.
Deluge Sprinkler System
Deluge sprinkler systems are similar to pre-action sprinkler systems in that they rely on a trigger, like a smoke detector, to release water to the sprinkler heads.
However, deluge sprinkler systems release water to every sprinkler in the system all at once. Instead of water spraying from just a few nearby sprinklers, water flows from the whole system.
Fire Sprinkler Systems Compliance
Staying compliant with the Los Angeles fire code requires regular inspections. At a minimum, users should have their sprinklers inspected at least once a year, but it’s a good practice to check on component parts more frequently.
Ideally, users should have gauges inspected once a month and pipework inspected at least once annually. It’s also a good idea to perform a basic inspection of the system on a quarterly basis. These routine inspections align with standard commercial fire sprinkler requirements and are a key part of preventive maintenance.
Staying compliant not only ensures the safety of the property and occupants but also helps keep overall costs lower by identifying emerging issues early—while they’re still easy and affordable to fix.
Replacing Fire Sprinkler Heads
Fire sprinkler heads are usually very sturdy. They are designed to last for anywhere between 20 and 50 years, depending on the environment.
Harsh environments, or exposure of corrosive agents or chemicals, can degrade sprinkler heads so that they need replacement earlier in the lifecycle.
Routine inspections and maintenance will alert users to any issues with the fire sprinkler heads, so that users can stay ahead of a system failure. Regularly inspecting the fire sprinklers can also protect people and property from fire — and help users remain compliant with the LA fire code.
The cost of commercial fire sprinkler system
The commercial fire sprinkler installation cost will depend on the location, the size of the facility, and the type of sprinkler one is installing.
Remember, the cost of failing to install fire sprinklers can be very high. Fire sprinklers keep the occupants safe and protect the property from fire damage. It’s also important to stay compliant with state and local laws. Failure to comply can lead to fines and other penalties.
