Fire Monitoring Requirements in Southern Nevada: What Building Owners Need to Know
Why monitoring matters
If your building in Southern Nevada has a fire alarm or a fire sprinkler system, it almost certainly must be monitored 24 hours a day. Monitoring means a listed central station receives signals from your system and calls the fire department when there is a fire.
A fire alarm that only sounds inside the building helps people get out. A monitored system also gets help on the way, even at 2 a.m. when the building is empty.
The rules just changed. Clark County adopted the 2024 International Fire Code (IFC) with local amendments, effective January 2026. If you have not looked at your monitoring setup in a while, now is a good time.
Which codes apply, and who enforces them
Monitoring rules in Southern Nevada come from three places:
The International Fire Code (IFC), as adopted by your city or county. It says which systems must be monitored.
NFPA standards. NFPA 72 covers fire alarms and how signals are sent. NFPA 13 and NFPA 25 cover sprinklers and their upkeep.
Local amendments. Each jurisdiction can add to or change the national codes.
Who enforces the rules depends on where your building sits. Clark County Fire Department covers unincorporated areas, including the Las Vegas Strip. The cities of Las Vegas, Henderson, North Las Vegas, Boulder City, and Mesquite each have their own fire department and code adoption.
The Southern Nevada jurisdictions write many amendments together, so the rules are similar. But they are not always the same. Always check with the fire department that has jurisdiction over your address.
Which buildings need monitoring
In short: if the code requires your fire alarm or sprinkler system, the code almost always requires it to be monitored too.
Fire sprinkler systems. IFC Section 903.4.1 requires automatic sprinkler systems to be supervised by an approved supervising station. There are a few narrow exceptions, such as sprinklers in one- and two-family homes and limited area sprinkler systems.
Fire alarm systems. IFC Section 907.6.6 requires required fire alarm systems to be monitored by an approved supervising station under NFPA 72. Stand-alone smoke alarms in homes are not included.
This covers most commercial buildings: offices, restaurants, retail stores, warehouses, hotels, schools, churches, and apartment buildings with sprinklers.

How signals get to the central station
For years, most fire alarm panels called the central station over two copper phone lines. Phone companies are now shutting down those copper lines across the country. When the line goes dead, your system can no longer call for help.
NFPA 72 allows several other ways to send signals:
Cellular communicators. A dedicated cell radio sends signals over the cell network. No phone line needed.
Internet (IP) communicators. Signals travel over the building's network, usually with cellular as a backup.
Private radio networks. Signals hop from building to building over a dedicated radio network. Ace Fire Systems runs its own AES radio monitoring network in Southern Nevada, Pahrump, Laughlin, Mesquite, & St. George.
If your panel still uses phone lines, ask your fire protection company about switching before your carrier forces the issue. A lost connection shows up as a trouble signal, and a system that cannot communicate is not truly monitored.
Keeping your monitoring in good standing
Monitoring is not a one-time setup. To stay in compliance, building owners need to keep up with three things.
Testing and inspection. Fire alarm systems must be tested under NFPA 72, and sprinkler systems under NFPA 25. NFPA 72 requires that your monitoring system is checked at least semi-annually. Part of that test is making sure signals actually reach the central station.
Impairments. When a system is out of service, the fire department may need to be notified. It may also require a fire watch until the system is fixed. Clark County's local amendments set rules for impairment notices and for reporting deficiencies found during inspections.
Contract changes. Nevada Admistrative Code 477 also address what happens when an inspection or service contract is canceled, so the fire department is not left in the dark. Do not let a monitoring contract lapse without a replacement in place.
A quick checklist for building owners
Confirm your fire alarm and sprinkler systems are monitored by a listed central station.
Find out how your panel sends signals. If it uses copper phone lines, plan an upgrade.
Check that your semi-annual inspections are current.
Know who to call when your system is impaired, and when a fire watch is needed.
Keep your monitoring contract active, with no gaps when you switch providers.
