Most people think of fire protection as one item on their to-do list, annually.
One inspection.
One checklist.
One “we’re covered.”
But in reality, your building’s fire protection includes various systems, working together or independently, each one designed to do a different job, and governed by different inspection, testing, and maintenance requirements.
When those differences aren’t clear, that’s when gaps in your level of protection occur.
In this post, we’re breaking down the most common fire protection systems, what they’re designed to protect, and why their inspection schedules and maintenance requirements aren’t interchangeable.
Fire alarm systems are designed for one primary purpose: life safety.
They detect smoke or fire, alert occupants to evacuate, and notify emergency responders. Because of this critical function, building owners and managers must follow strict inspection, testing, and maintenance requirements established by national and local fire and life safety codes.
Missed testing or unaddressed deficiencies can lead to:
Inoperable or impaired systems
Increased risk of injury or loss of life during an emergency
Code violations and fines
Greater risk of property damage during an incident
If you’re unsure of how often your fire alarm needs to be inspected or tested, you can download our Fire Alarm Inspection & Testing Frequency Cheat Sheet, which is a helpful guide to interpreting the requirements of NFPA 72 National Fire Alarm and Signaling Code.
Fire sprinkler systems work differently.
They’re designed to control or suppress a fire, giving building occupants time to evacuate and limiting damage until first responders arrive. And while they’re extremely reliable, many sprinkler issues aren’t obvious day to day.
Common fire sprinkler issues include:
Closed or partially closed valves
Obstructed or compromised sprinkler heads – even something as small as a speck of paint can keep a sprinkler from doing its job. Our blog, The Painted Head: A Multi-Family Fire Protection Nightmare, breaks down how minor damage can create major risk and what to watch for.
System components that degrade or malfunction without visible signs
That’s why regular inspection and testing is critical, even when everything “looks fine.”

Fire extinguishers are often the most visible form of fire protection in a building — and sometimes the most overlooked.
They require:
Monthly visual checks
Annual inspections
Maintenance at very specific intervals (6 years, 12 years, etc…)
Proper placement and signage
Overdue fire extinguisher maintenance (6‑year or hydrostatic testing) is one of the most common inspection deficiencies, along with units that are low on pressure or completely discharged and in need of refill.
Use our Fire Extinguisher Visual Inspection Checklist as a worksheet for the monthly visual inspections of your fire extinguishers as well as a record of any deficiencies found that will require action.
Special hazards systems are used in spaces where traditional suppression using water could damage mission critical or high value assets, such as:
Data centers / server rooms
Aircraft hangars
Manufacturing or high-value equipment areas
Commercial kitchens
Museums and archives
These systems address specific hazards, which change over time as operational risks and customer needs evolve.
Not sure whether water or clean agent suppression is right for your space?
We break down the differences between automatic sprinklers and clean agent fire suppression systems so you can make the right call for your people, property, and critical assets. Read: Automatic Fire Sprinklers vs. Clean Agent Systems.
Most compliance issues don’t come from neglect. They come from:
Assuming an annual inspection is all that is required
Doing the same thing as last year
Failing to coordinate testing with vendors and contractors whose systems are integrated
Understanding what applies to your building and what doesn’t, is the first step to staying compliant and protected.
We spend a lot of time helping teams sort through:
Which fire protection systems need to be inspected and at what frequency
What periodic maintenance is required
How to prioritize repairs so they work with your annual budget
No pressure. No overcomplication. Just clarity. If you want a second set of eyes on your systems or inspection schedule, we’re happy to help. Get in touch.

Below are answers to common questions we get about fire alarm, sprinkler, extinguisher, and special hazards inspection requirements.
No. Fire alarm, fire sprinkler, fire extinguisher, and special hazards systems all serve different purposes and follow different inspection and testing requirements.
Fire alarm inspection and testing frequencies vary by device and function. Some components require monthly checks, while others are tested quarterly, semiannually, or annually. Staying compliant requires following the standards adopted by your state and local jurisdictions, which is typically NFPA 72.
Sprinkler system deficiencies or issues are not often visible and unlike a fire alarm, you aren’t always alerted of a problem.
Closed valves, degradation of internal valve components, pressure issues, pipe corrosion or internal obstructions may only be discovered during the required inspections. Regular testing and internal investigations help catch these issues to minimize the negative impact on the system performance.
Common issues include extinguishers that are past due for extended maintenance, like 6-year maintenance and hydrostatic testing. Also missing units, empty cylinders, blocked access, improper mounting, and expired tags (i.e. missed annual inspections). These are some of the most frequently cited deficiencies during annual fire extinguisher inspections.
Special hazards systems are designed to protect areas where traditional water may not be the best form of fire suppression. This includes hazards such as data centers, server rooms, switch gear rooms, electrical rooms, museums and data archives. These systems address very specific high value or mission critical hazards, which continuously evolve as operational risks and customer needs change.
