Fire Alarm Installation, Testing & Monitoring

Fire alarm systems must be tested and inspected under NFPA 72, the National Fire Alarm and Signaling Code — annually at minimum, with some components on more frequent schedules. Our directory connects you with licensed fire alarm contractors for code-required testing, new system design and installation, panel upgrades, and central-station monitoring.

An alarm system that hasn't been tested is a liability twice over: it may fail in a fire, and it will fail your next fire marshal inspection. Buildings with monitored systems also need a UL-listed central station connection — something the licensed contractors in our network can provide or arrange.

Frequently Asked Questions

NFPA 72 requires a complete functional test at least annually, with visual inspections and sensitivity testing on their own schedules. Your local fire code may add requirements, so a licensed local contractor is the right source for your building's exact schedule.

Most commercial occupancies with required fire alarm systems must transmit signals to a constantly attended location — typically a UL-listed central station. Your occupancy type and local code determine the requirement; alarm contractors in our directory can confirm and set up monitoring.

Annual testing for a small commercial building typically runs $300–$800, scaling with device count. Bundling alarm testing with sprinkler and extinguisher service through one contractor often reduces total cost.

A trouble signal means the system has detected a fault (wiring, battery, communication) and may not function fully in a fire. Don't silence it and move on — call a licensed fire alarm contractor promptly to diagnose and clear it.
