Fire Sprinkler

Fire Sprinkler

Few fire protection contractors understand the nuances of fire sprinkler systems like we do. Harnessing our extensive fire experience, we specialize in industrial and commercial sprinkler system design, installation and maintenance of practically every fire sprinkler system available. From complex deluge systems for high hazard areas to state-of-the-art preaction systems for minimizing water damage, to the most common of wet pipe systems—you can trust Ahern to do the job right the first time.

Installation &Service

With Ahern as your fire protection systems installer, you’re partnering with a team of code experts looking out for your safety, schedule, and budget. From commercial fire sprinkler system design and prefabrication to installation, testing, and fire sprinkler maintenance, we’ll ensure your systems follow code requirements and are properly designed to meet your facility needs.

We service all types of sprinkler systems in all sorts of facilities. Our sprinkler inspectors undergo a minimum of 720 hours of coursework and 9,500 hours of on-the-job training prior to performing any inspections. This ensures they carry the code and system knowledge needed to keep your commercial fire sprinklers functioning properly. Ahern also has expertise in fire suppression systems and fire alarm and control. We have 15 locations throughout the Midwest. Find a location near you!

I consider them more than simply a contractor, they are a valued part of our team.


Deluge Systems

A deluge sprinkler system refers to open sprinkler heads attached to system piping. The system is activated through a separate detection system. Following system activation, water will discharge from all sprinkler heads. Deluge systems are installed to protection high-hazard areas, such as aircraft hangers.

Dry Pipe Systems

Dry pipe fire sprinkler systems refer to sprinkler heads attached to piping containing a gas (nitrogen or air) under pressure. Following system activation, the gas will be expelled and allow water to travel through the system piping to the affected areas and control fire growth. Dry pipe sprinkler systems are commonly installed in areas subject to freezing temperatures.

Fire Pumps

Fire pumps are utilized to boost the water pressure for use with sprinkler systems.

Preaction Systems

Preaction sprinkler systems refer to sprinkler heads attached to piping containing a gas (nitrogen or air) under pressure with a separate detection system. Since two trigger conditions need to occur before activation, this type of system is used when water damage from false system activation could cause significant or non-repairable property damage.

Private Fire Service Mains

Piping installed on private property that supplies sprinkler systems, private tanks, or private fire hydrants. This piping may or may not be buried underground.

Quell Design Method

The Quell Design Method was created to protect cold storage warehouses. This method is desirable to these facilities because it eliminates the need for in-rack fire sprinklers.

Stand Pipe Systems

Standpipe systems are an arrangement of piping that supply fire hose connections installed in high-rise buildings.

Wet Pipe Systems

Wet pipe fire sprinkler systems are the most common type of fire protection system. Wet pipe refers to sprinkler heads attached to piping containing water, that when activated will immediately begin to control fire growth. Contrary to movie depictions, fire sprinklers for these systems do not all activate simultaneously; only sprinklers covering a high heat area will activate.

Wet Pipe Systems

In 2023, we have completed over 26,000 sprinkler inspections.

Ahern is, and has always been, a premier contractor to deal with…I highly recommend Ahern and appreciate all they do for us.
