Fire alarm testing in Los Angeles
NFPA 72 sets the minimum. A fire alarm system has to be inspected and tested at least once a year, and some of the devices on it need attention more often than that. On a typical visit the technician starts at the control panel, checks for trouble and supervisory signals, then works through the building: smoke and heat detectors, pull stations, horns and strobes, and the signal that goes out to your monitoring company. Failed devices get noted for repair.
Does the building have sprinklers? Then the alarm usually watches them too, because waterflow switches and valve tamper switches report to the panel and a sprinkler problem can show up there first. Those switches are part of the alarm test.
Got a notice from the fire department?
Some calls start with a letter. In the City of Los Angeles, business fire code enforcement belongs to the LAFD Fire Prevention Bureau, the Fire Marshal's office, which has separate units for industrial and commercial buildings, public assembly, and schools, churches and institutions. Tell us the deadline when you call. Our alarm technician often books one to two weeks out, so the sooner you reach us, the more room there is to fit the visit in before your date. Keep the notice handy.
Pre-1974 high-rises adding sprinklers
High-rise owners have one city rule to know. Under the Los Angeles high-rise retrofit ordinances (Ordinances 163836 and 165319, tied to LAMC Section 91.8604), existing high-rises built before 1974 must meet that section, with Group R-1 residential buildings exempt. Once sprinklers go in, the fire alarm has to monitor waterflow and valve tamper on every floor. So the sprinkler job is also an alarm job.
Repairs, new devices and panel work
We also repair failed detectors, replace standby batteries and clear panel trouble signals; our page on fire alarm repair in Los Angeles covers that work. Adding devices, moving them or swapping a panel can raise permit questions. For new construction, LAFD Fire Development Services at the One Stop Permit Center handles plan review, permit approvals and field inspections. Changing an existing system? Check permit requirements with LAFD before work starts.
Who may work on your alarm
California work for 1 Pro Fire is done by Hedrick Fire Protection. Hedrick holds a C-10 electrical contractor license and a C-16 fire protection contractor license, and is licensed by the California State Fire Marshal under Title 19 for extinguisher service and for inspection, testing and maintenance of water-based systems. One company, both trades. Need extinguishers handled too? See annual extinguisher certification in Los Angeles or extinguisher training for staff, or start at our Los Angeles service page.
Is your address inside the city?
Not every LA mailing address is. ZIP 90022 is mostly East Los Angeles, 90023 is listed under Commerce and East Los Angeles, 90040 is the City of Commerce, and 90058 is shared with Vernon, so buildings there may answer to a different fire agency than LAFD. For those areas, see fire alarm service in Los Angeles County. We also cover fire alarms in Orange County.

Fire alarm questions from Los Angeles
Why does my smoke detector keep chirping after I changed the battery?
Often the unit has reached end of life or has a fault. If it's part of a building alarm system, the panel may be showing trouble as well, and a technician can read the panel to find the device.
How often does a fire alarm need testing?
At least once a year under NFPA 72. Some devices need it more often.
Who enforces fire alarm rules for my business in Los Angeles?
The LAFD Fire Prevention Bureau. Plans and permits for new construction go through LAFD Fire Development Services.
