When it comes to protecting the lives of your staff, your property, and your business, your fire alarm system is one of the most important safety tools in the building! But simply installing a fire alarm system isn’t going to cut it. Without regular maintenance, even the most advanced system can fail, which could result in costly fines, increased liability, or even worse, catastrophic loss during an emergency.
Let’s go over some things that’ll help you as a business owner, facility manager, or a building operator in Arizona, as you’ll need to know how to keep your fire alarm system compliant, functional, and ready to perform when it matters most.

Why Fire Alarm Maintenance Matters ?
Failing to maintain your fire alarm system isn’t just risky, it’s actually illegal. The National Fire Protection Association (NFPA 72) and local fire codes require regular testing, inspections, and servicing. Local AHJs (Authorities Having Jurisdiction) can issue citations for non-compliance, and insurance carries may deny claims if it’s proven that your system was not properly maintained.
At Titan Alarm & Fire, we’ve seen firsthand how routine maintenance can detect issues early, save lives, and preserve property. Our licensed fire technicians inspect thousands of systems across Phoenix, Tucson, and all of Arizona to help business owners stay compliant and most importantly, protected.
How Often Should a Fire Alarm System Be Serviced?
According to NFPA 72 standards and most local codes:
- Visual Inspections: should be conducted monthly
- Functional Testing and Device Sensitivity Checks: should occur at least annually
- Battery Checks: are recommended semi-annually
- Full System Inspections: are required once a year at minimum by a certified fire alarm professional.
Depending on your occupancy type, insurance policy, or local jurisdiction, additional checks may be required quarterly or semi-annually.
Fire Alarm System Checklist
I’ve made a detailed checklist divided into Monthly, Semi-Annual, and Annual maintenance tasks that you can reference below. While some of these tasks can be done in-house, most require a certified fire technicians. Also remember, this is a general list, so make sure to take the advice of your local fire technician on when these tasks should be completed for your system specifically.
Monthly Fire Alarm Maintenance Tasks
Visual Checks:
- Ensure control panel is powered and free of faults or trouble alerts.
- Check for physical damage to pull stations, strobes, smoke detectors, and horns
- Verify that manual pull stations are accessible, clearly labeled, and unobstructed
- Ensure smoke detectors are not blocked or covered by dust, paint, or tape.
- Confirm that notification appliances (strobes, horns) are not obstructed by shelving or signage.
Documentation
- Log any system trouble alerts and the steps taken to correct them.
- Document battery voltage if using an unmonitored panel.
- Not any alterations to the building layout that may affect alarm coverage.
Semi-Annual Maintenance Tasks
Battery Inspection:
- Test and record the voltage of standby and primary batteries.
- Ensure terminals are clean, tight, and corrosion-free
- Replace batteries if voltage is below manufacturer specs or nearing expiration.
Alarm Panel Diagnostics:
- Review event history log for faults, alarms, or resets.
- Verify communication to the monitoring center (if monitored).
Initiating Device Testing (partial):
- Conducting a rotating test of a portion of devices, such as smoke detectors or heat detectors, to meet rolling annual requirements.
- Test one-third of detectors every 6 months to meet full coverage annually.
Annual Fire Alarm Maintenance Tasks (Performed by Certified Technician)
Control Panel Testing:
- Simulate alarm conditions to ensure panel responds correctly.
- Confirm supervisory and trouble signals activate as intended.
Initiating Devices:
- Smoke Detectors – Test using UL-approved smoke test aerosol.
- Heat Detectors – Test with a heat gun to confirm threshold activation.
- Pull Stations – Activate each to ensure panel response.
- Duct Detectors – Confirm fan shutdown and alarm signal are functional.

Notification Appliances:
- Activate horns, bells, chimes, and strobes throughout the building.
- Ensure audio coverage meets NFPA audibility and visibility standards.
System Integration Testing:
- Confirm elevator recall, door release, HVAC shutdown, and sprinkler/suppression connections are working properly.
Monitoring Service Validation:
- Verify system signals are received by central station monitoring.
- Conduct supervised line or cellular communicator tests.
Sensitivity Testing:
- Perform sensitivity analysis on smoke detectors to ensure they activate within the manufacturer’s threshold.
Device Inventory Review:
- Ensure all devices are accounted for on the system map.
- Label new or relocated devices to reflect changes to the building.
Code Compliance Review:
- Confirm system aligns with current NFPA, UL, and local fire marshal requirements.
(Remember, these checklists include general best practices for maintaining a fire alarm system, but every building and system is unique. Always consult with a licensed fire protection professional (like Titan Alarm & Fire) to ensure you’re meeting the specific requirements of your system, local codes, and insurance policies.)
Additional Maintenance Tips
Train Employees – Teach staff how to operate the panel, silence false alarms, and. evacuate the building.
Keep the Panel Accessible – Do NOT block or lock access to the fire alarm control panel.
Respond to Trouble Signals Promptly – Don’t ignore a “trouble” indicator. It’s often a good indication of a wiring issue, faulty detector, low battery, or some other issue.
Update Your System Map – Maintain an updated zone map next to your panel to aid in quick response time.
Work With Certified Professionals – Only licensed technicians should. perform annual inspections and repairs to remain compliant with code.
