Commercial Fire Compliance FAQs
How often does NFPA require fire alarm inspections?
Most commercial systems require annual inspection at minimum, with some components tested semi-annually or quarterly depending on occupancy type and local AHJ requirements. We track your schedule so you never miss a deadline.
Can you service a fire alarm system installed by another company?
Absolutely. We regularly take over existing fire alarm systems, regardless of who originally installed them. Our technicians can inspect, repair, monitor, and maintain most major manufacturers.
