How to Prepare Your Fire Alarm System for Hurricane Season in Hawaii and Guam

Guidance for Commercial and Government Building Owners

Hurricanes place tremendous stress on fire alarm systems. In regions like Hawaii and Guam, where recovery resources can be delayed, preparation is essential for every building owner. It is a key part of life safety planning. A robust plan not only minimizes the risk of system failure but also shortens the time it takes to return to safe, reliable operation after a storm. It also reduces costs, prevents code violations, and ensures staff can respond confidently during emergencies. 

Keep reading to learn more about the practical steps you can take to safeguard your system before, during, and after hurricane season. This guide will walk you through each stage clearly and help you feel more confident in your preparedness.

Why Preparation Matters

Storm damage goes beyond wind and rain. Power loss, surge damage, communication outages, and water intrusion can all compromise a fire alarm system when it’s needed most. In decades of supporting government and commercial clients, the team at Phoenix Pacific has seen these issues play out time and again. For example, a system that worked perfectly on Friday can be offline by Monday due to water that infiltrated panels during the storm and caused corrosion weeks later.

Common System Failures During Hurricanes

Understanding how hurricanes damage fire alarm systems is the first step toward building a more resilient facility. These are the most frequent causes of failure during severe weather events.

Power Loss

Commonly, the fire alarm system’s backup batteries are depleted or aging and the primary power is not connected to a backup generator. As such, the system goes down or becomes more of a nuisance than a help. Without a generator connection, your fire alarm system can remain disabled for days.

Surge Damage

Lightning strikes and unstable utility service, sometimes called “dirty power,” cause voltage spikes that irreparably damage control panels and detectors, especially when surge protection is missing or outdated. Modern surge protection devices reduce this risk significantly.

Communication Failures

Monitoring disruptions occur when phone lines, cellular networks, or IP services go offline. The dangerous part is that these failures aren’t always obvious. Facilities have discovered days or weeks later that their systems couldn’t transmit alarm or trouble signals.

Water Intrusion

Heavy wind-driven rain penetrates deeper into structures. Moisture trapped behind panels corrodes components or creates shorts long after the storm clears. It is not uncommon to open panels months after a storm only to find pooled water inside.

Untrained or No Response

Even the best-designed systems fail without qualified personnel to monitor, test, and reset them before and after an event. Small faults ignored during recovery can become major problems later.

Pre-Hurricane Preparation Steps

It is a good idea to begin by inspecting all batteries, power supplies, and surge protection. Test your generators and confirm they can sustain the system through prolonged outages. NFPA 1600 emphasizes the importance of having redundant communication methods to maintain monitoring service.

Additionally, train your staff to recognize and respond to system trouble signals, and assign clear responsibilities for storm preparation and post-event checks. 

During the Storm

If conditions are safe, monitor the system status closely and note any alarms, faults, or abnormal readings that appear during the event. Keep display panels visible and accessible to enable quick response, and use a backup communication method to verify system health with offsite contacts. Monitor generator performance and power quality. Remember to keep in contact with your monitoring service to confirm that signals are still transmitting.

After the Storm Passes

A full inspection is essential. Test all communication pathways, check panels for water intrusion, and document any damage or irregularities. Systems may appear functional after a storm. However, hidden moisture can cause corrosion over time, leading to delayed or intermittent faults. In addition, wiring insulation can deteriorate gradually, and terminals may loosen or oxidize, creating intermittent faults that are hard to detect without thorough testing. We highly recommend documenting every step of this process to support insurance claims and code compliance.
