Fire Alarm in Los Angeles County

Your fire alarm is an electrical system. It also watches your sprinklers. In California our work is done by Hedrick Fire Protection, which holds a C-10 electrical contractor license and a C-16 fire protection contractor license, so one crew can work on the panel wiring and on the waterflow and tamper switches at a sprinkler riser. We test, repair and install systems for businesses across Los Angeles County.

The yearly test, device by device

NFPA 72 requires the whole system to be inspected and tested at least once a year. Some devices come due more often. On a typical visit the technician checks:

• The control panel, its trouble and supervisory signals, and the backup batteries.
• Smoke and heat detectors, pull stations, and sprinkler waterflow and tamper switches, each tripped and confirmed at the panel.
• Horns and strobes.
• The signal path to the monitoring station, if the system is monitored.

Expect a few findings. Detectors age, batteries weaken and remodel crews sometimes cut wiring, so a yearly test often ends with a short repair list, which our fire alarm repair service in Los Angeles County can take from there.

Permits and plans for new alarm work

Adding devices, swapping a panel or installing a new system usually means plans and a permit. Who reviews them depends on the address.

• Unincorporated areas and contract cities: the Consolidated Fire Protection District of Los Angeles County (County Fire) covers all unincorporated areas plus 59 contract cities in the county. Its Fire Prevention Division does new construction inspections, minor plan checks and annual business inspections through North, Central and East regional units.
• City of Los Angeles: LAFD's Fire Development Services section reviews plans, approves permits and inspects new construction inside city limits. Requests go through inspect.lafd.org.
• Cities with their own bureau: Burbank is one example.

Codes differ too. County Fire works from Title 32 of the County Code, which amends the 2022 California Fire Code and is adopted by reference in contract cities such as Santa Clarita, while the City of Los Angeles keeps its own fire code. Confirm the current edition with your fire authority before a panel swap.

Alarms that have been off for a while

Some panels sit dark for years. In Rancho Santa Margarita, in Orange County, we reactivated a fire alarm that had been dormant for two years. A system in that state needs a full test before anyone relies on it, because batteries, detectors and the monitoring connection may all have lapsed while the panel was off. Don't skip that step.

Fire alarm questions

How often does a fire alarm need testing?

At least once a year under NFPA 72. Some devices are due sooner.

Which agency covers my building?

It depends on the city: County Fire covers unincorporated areas and its contract cities, LAFD handles plan review and new construction in the City of Los Angeles, and some cities such as Burbank run their own fire prevention bureau.

Can a long-dormant alarm be brought back?

Often, yes. Plan on a full test first.

Do I need a permit to replace my panel?

Usually. Ask the fire authority for your address what plans it wants before work starts.
