Fire System Testing and Inspection

Testing helps ensure your systems work properly and are in compliance with NFPA, local, state, and national codes to ensure minor issues and deficiencies are identified and corrected before they cause major disruptions.

One Ideal Partner for Your Complete Fire Solution

Early detection and suppression of a fire can save lives and minimize property damage. But simply installing fire detection, alarm, and suppression systems isn’t enough. These systems require regular testing to ensure they’ll be ready if a fire incident occurs. Still, many property owners, facilities, and life safety teams fail to schedule regular fire and life safety system inspections. Everon’s team of certified fire and life safety professionals can provide the necessary testing and inspections—all on the appropriate schedule—to keep your facilities up to code and keep your systems working properly.

Testing and Inspections Are Critical

Although protecting lives and staying up to code are the primary reasons to test and inspect your system regularly, there are also other reasons:

  • You may not know there is a system issue without testing
  • You can limit your liability in the event of an incident
  • Insurance carriers, local building departments, and local fire inspectors may require it
  • Reduce nuisance alarms and associated costs with false triggering

Fire Suppression System Inspections

With our decades of experience, you can trust that we know the local fire code requirements for your building’s pipes and valves. We can provide periodic inspections that can save you money by discovering small problems before they turn into big issues, and help keep you in compliance with NFPA 25 standards.

The NFPA requires an internal inspection of water-based sprinklers every five years. Be sure to schedule this important service with Everon’s team of fire suppression experts. Your Everon team will look for two main problems during their inspection of your sprinkler system: piping obstruction and internal valve damage or malfunction. The piping obstruction inspection looks inside your system with an internal camera for identification of possible materials or conditions that could cause pipe blockage. 

The following four points of your sprinkler system are examined internally: 

  • System valve
  • Crossmain
  • Riser
  • Branchline

If an obstruction is discovered, our team can perform a flushing program to help keep your system’s performance in optimal condition. 


During the internal valve inspection, we will open and inspect each valve—examining their associated strainers, filters, and restriction orifices. The inspection is performed in addition to the yearly operational test of all valves.

NFPA 25 requires five-year inspections, but that’s not the only reason you should have them. Blockage and corrosion can cause leaks and damage that could result in costly repairs or even the replacement of your entire system piping. A blocked pipe or valve can also prevent a system from working, rendering it ineffective and putting lives at risk.

Our experienced technicians are certified to perform fire suppression inspections. They will visually check each component of your fire suppression system to make sure that it is fully functional and in compliance with NFPA requirements.

Advanced Detection

Through active air-sampling smoke detection (ASD), Everon can help detect the earliest signs of fire in the incipient stage. Early warning detection and prevention is critical to identifying potential risks to occupants, key stakeholders, and first responders who may be threatened by carbon monoxide, smoke, heat, and environmental gases.
