How Long Can You Expect Your Fire Alarm System to Last?

Published on 27 December 2024 at 14:45

Generally, a fire alarm system will serve you effectively for about 10 to 15 years—assuming it receives consistent maintenance. However, inadequate care can lead to earlier malfunctions and inefficiencies. Additionally, if your building undergoes renovations or expansions, you might need to bring your system up to the latest fire safety standards. For best results, plan on replacing your fire alarm system every 10 years or sooner.

To keep your system compliant and protect your building, schedule routine inspections and maintenance at least every three to six months. You should also test your detectors once a month to ensure they’re functioning properly. Regular testing reduces the risk of catastrophic loss by confirming your system’s readiness.

How Do I Know It’s Time to Replace My Fire Alarm?

Over time, detectors can accumulate dust, cobwebs, and other debris that hamper their performance. This can result in false alarms caused by oversensitivity or a lack of proper fire detection. Additionally, many don’t realize detectors expire because of the wear and tear on batteries and sensors. For optimal protection, replace your fire detectors at least every 10 years, and carbon monoxide detectors every 7 years.

If your system is approaching the end of its recommended lifespan or isn’t functioning correctly, it’s time to consider a replacement. For older systems, it’s worth conducting a feasibility study with our fire contractors to see whether your current system can be upgraded or extended. Reach out to us at (346)-528-5971 to schedule a consultation.

Waiting until your system completely fails can be costly. Unplanned installations typically require more money, cause greater disruption, and take longer to complete than proactive replacements. Furthermore, a non-functioning system puts you at risk of non-compliance and potential fines.

When Should You Upgrade A Fire Alarm System?

If your system is less than a decade old but you’re expanding the building or adding more devices, an upgrade might be sufficient. Your current system’s capacity and wiring will be major factors in that decision. However, the system’s age remains critical. In many cases, retrofitting or reusing older components can end up costing as much or more than installing an entirely new system, complete with updated equipment, devices, and wiring.

Once a manufacturer discontinues support for a particular product, maintenance and part replacement can become increasingly difficult and expensive. If you also need to meet new code requirements, the existing wiring may be incompatible with newer devices. It’s best to consult a trusted contractor or consultant to evaluate the expenses and feasibility of wiring, device needs, and system load.
