Summer in New England brings warmer weather, longer days, and plenty of outdoor activity—but it also brings some of the most unpredictable weather of the year. Thunderstorms can develop quickly, bringing lightning, heavy rain, strong winds, and power disruptions that can impact commercial facilities with little warning.
For facility managers and property managers, severe weather often creates an immediate list of priorities: checking for physical damage, addressing leaks, restoring power, coordinating repairs, and returning operations to normal.
One critical building system that should not be overlooked after a storm is your fire protection system.
Fire alarm systems, sprinkler systems, fire pumps, monitoring equipment, and other life safety systems are designed to provide reliable protection when they are needed most. However, like any building system, they can be affected by severe weather conditions.
Lightning strikes, electrical surges, power interruptions, and water intrusion can create problems that are not always immediately visible. A building may appear to be operating normally while a fire protection system has experienced damage or developed an issue that could affect performance later.
For facility leaders across industries—including healthcare, manufacturing, commercial real estate, schools, data centers, utilities, and other critical facilities—the goal is the same: understand the risks, know what warning signs to look for, and have a plan when severe weather affects your building.
Commercial fire protection systems are designed with reliability in mind, but they are also connected to the larger infrastructure of a facility.
Modern fire protection systems often rely on electrical power, electronic controls, communication pathways, and monitoring connections. When severe weather affects a building's electrical or communication systems, those impacts can extend to life safety equipment.
Summer storms can create several challenges, including:
· Lightning-related electrical surges
· Utility power interruptions
· Voltage fluctuations when power is restored
· Water intrusion into equipment areas
· Flooding in mechanical or electrical spaces
· Heat and humidity that place additional stress on equipment
Not every storm will cause damage. However, severe weather events can reveal existing issues, affect sensitive components, or create conditions that may impact reliability later.
For facility managers, storm response is not just about restoring operations—it is about confirming that critical systems are still ready to perform.
One of the biggest misconceptions about lightning damage is that a building must experience a direct strike for equipment to be affected.
That is not always the case.
Nearby lightning strikes can create electrical surges that travel through utility lines, communication pathways, and building infrastructure. These surges can affect sensitive electronic components throughout a facility.
Fire protection equipment that may be impacted includes:
· Fire alarm control panels
· Monitoring communication equipment
· Fire pump controllers
· Electronic sprinkler monitoring devices
· Backup power components
Sometimes the impact is obvious. A fire alarm panel may display a trouble condition, communication with the monitoring station may be interrupted, or equipment may fail to return to normal after power is restored.
Other times, the effects are less noticeable. A component may continue operating while experiencing internal damage or reduced reliability.
This is why a system appearing normal after a storm does not always mean there was no impact.
Power outages are one of the most common effects of summer storms.
Commercial fire alarm systems are designed with backup power capabilities to help maintain operation during an outage. However, both the loss of power and the process of restoring power can affect connected equipment.
When utility power returns, electrical fluctuations can place additional stress on electronic components.
After a significant power interruption, facility teams should verify that critical systems have returned to normal operation.
Pay attention to:
· Trouble or supervisory conditions
· Communication failures
· Unexpected system messages
· Fire pump controller conditions
· Equipment behaving differently than usual
A restored electrical supply does not always mean every connected system has fully recovered.
Life safety systems should be verified—not assumed.
Lightning and electrical issues often receive the most attention, but heavy rain and flooding can create additional concerns.
Water intrusion into electrical rooms, mechanical spaces, sprinkler riser rooms, or equipment areas can affect fire protection components and supporting infrastructure.
Even when water does not directly damage equipment, moisture can create conditions that contribute to future reliability issues.
After significant rainfall, facility teams should look for:
· Water near fire protection equipment
· Flooding in mechanical spaces
· Roof leaks or building envelope issues
· Moisture around electrical components
Identifying these issues early can help prevent small problems from becoming larger operational concerns.
One of the most important things for facility managers to understand is that storm-related damage is not always immediately obvious.
In many cases, the biggest challenges after severe weather are not complete system failures. They are smaller issues that develop over time.
A power surge may weaken a component without disabling it. A communication problem may temporarily resolve itself. A trouble signal may appear intermittently.
These situations can be easy to overlook when facility teams are focused on restoring normal operations.
However, unusual system behavior provides valuable information.
If your facility experiences:
· Repeated trouble signals
· Unexpected resets
· Communication interruptions
· Electrical irregularities
· Equipment behaving differently after a storm
those details should be documented and evaluated.
A functioning system is a positive sign, but it does not always confirm that every component is unaffected.
Electronic components can experience stress without immediately failing.
Resetting a panel may clear a warning, but it can also remove information that helps technicians determine what happened.
Document first and make sure the condition is properly understood.
A warning that appears and disappears may still indicate a developing issue.
Recurring or unusual conditions should not become background noise.
Routine inspections are essential, but storm-related concerns should be addressed based on the event—not simply delayed until the next scheduled visit.
Severe weather does not always happen during normal business hours. A lightning event overnight, a weekend power outage, or flooding during a holiday can require quick decisions.
Having a clear response plan can make storm recovery easier.
Facility teams should know:
· Who is responsible for checking system status after a storm
· Who has access to equipment areas
· Who contacts fire protection providers
· How concerns are documented
· How occupants or tenants are notified if needed
After a significant storm, facility managers should:
Check the fire alarm system.
Confirm that the panel has returned to normal operation and review any trouble, supervisory, or communication conditions.
Verify monitoring communication.
A fire alarm system is only effective if signals can reach the monitoring station.
Review fire pump and sprinkler system status.
Facilities with fire pumps should verify controllers have returned to normal operation after electrical disturbances.
Perform a visual walkthrough.
Look for water intrusion, visible damage, or unusual conditions near fire protection equipment.
Documentation is valuable. Recording what happened, when it occurred, and what was observed can help technicians troubleshoot more efficiently.
Severe weather cannot be prevented, but preparation can reduce its impact.
Routine inspection, testing, and maintenance help establish a baseline for how fire protection systems should operate. When something changes after a storm, those established expectations make problems easier to identify.
Preventive maintenance supports:
· Reliable system operation
· Faster troubleshooting
· Reduced unexpected downtime
· Better emergency preparedness
For facility managers, maintenance is not simply about responding to problems. It is about reducing surprises and ensuring critical systems are ready when they matter most.
After a significant summer storm, facility managers should:
✓ Confirm fire alarm systems have returned to normal operation.
✓ Check for trouble or supervisory conditions.
✓ Verify monitoring communication.
✓ Inspect equipment areas for water intrusion.
✓ Confirm fire pump equipment is operating normally.
✓ Document unusual system behavior.
✓ Contact a qualified fire protection provider if concerns remain.
