Fire Alarm System Service & Maintenance FAQ
What is the difference between a smoke detector and a fire alarm system?
A smoke detector is often a standalone device, whereas a fire alarm system is a network of smoke, heat, and pull-station sensors connected to a central control panel. For commercial buildings, these systems are required to be monitored and inspected annually to ensure life safety.
How often should a commercial fire alarm be tested?
Most fire codes require an annual functional test of all components (smoke detectors, pull stations, and horns/strobes) and a semi-annual visual inspection. LHR Fire Protection provides digital reporting and barcoding to make tracking these inspections easy for building owners.
My fire alarm panel is beeping. What should I do?
A beeping panel usually indicates a “trouble” or “supervisory” condition, such as a low battery or a dirty sensor. Contact us for a service call, we can diagnose the issue, clear the fault, and ensure your building is still protected.
Do you provide fire alarm inspections for residential apartment complexes?
Yes, we specialize in multi-family and commercial fire alarm inspections. We ensure your system meets all local NH safety regulations to protect your tenants and your property investment.

Our Clients Say
Posted on Google Jordan ShallowTrustindex verifies that the original source of the review is Google. Joe expedited my fire extinguisher inspection. I just googled them and they came down the next morning BEFORE my inspection. Thanks to the team. I highly recommend all of them and will use them in the future.Posted on Google RonTrustindex verifies that the original source of the review is Google. LHR Fire has been instrumental in getting our condominium complex's fire sprinkler system up to code. Our association is over 20 years old, and we discovered that the original installation had not been done correctly by a previous fire company, leading to leaks and ruptures over time. LHR worked with us to develop a plan for installing expansion tanks on the antifreeze lines and replacing the original check valves and sprinkler heads. They have diagnosed several longstanding issues. What impressed us most is their communication. They take the time to explain what they're seeing, discuss options, and work collaboratively to troubleshoot problems rather than simply replace parts. Overall, LHR is proactive rather than reactive. They take pride in doing the job right the first time, their technicians are knowledgeable and professional, and their pricing has been fair. I highly recommend them to anyone looking for a reliable fire protection contractor.Posted on Google Steven whiteTrustindex verifies that the original source of the review is Google.

We’ve worked with LHR Fire Protection at one of our business locations for several years, and they’ve consistently ensured that our fire protection systems remain up to code, fully compliant, and operating safely. Their attention to detail has given us tremendous peace of mind, knowing we can always rely on them to help keep our staff and customers safe. When we expanded to another location, Joe Keller conducted a thorough walkthrough, identified areas that needed to be brought up to current safety standards, and quickly implemented the necessary improvements. His knowledge, professionalism, and commitment to doing the job right made the entire process smooth and stress-free. We truly appreciate the professionalism, quality workmanship, and dedication to safety that Joe Keller and the entire LHR Fire Protection team demonstrate.
