Great service from start to finish. From my first call with Allie, to the electrical service performed by Brandon and Sam, which was unctual, skillful, and professional. Everyone I dealt with at LHR Electrical was very efficient and adept. Would definitely recommend and use again.

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 Paul DuclosTrustindex verifies that the original source of the review is Google. This company was absolutely outstanding to work with throughout our entire commercial renovation project. They are professional, provide a very reasonably priced service, handle all your fire safety needs, and are always there even in emergency last minute situations. We hired LHR Fire Protection to raise our sprinkler main in our warehouse space and rework the branch lines. The project did even start yet and one of our other contractors (not affiliated with LHR) broke a sprinkler head during demo. Josh from LHR was there within the hour to cap it off and get the rest of the building back up and running even though the ink from our contract hadn't even dried yet! They met all of our deadlines, were at every inspection on time, and surpassed our expectations with their impeccable service. Because we had such a great experience with them we are continuing to use them for our fire extinguisher annual inspections and know that we are in great hands. Thank you to everyone we worked with at LHR Fire Protection you truly deserve more than 5 stars!Posted on Barry SwansonTrustindex verifies that the original source of the review is Google.
