A fire alarm technician installs, programs, maintains and repairs the fire alarm systems that detect a fire and warn the people inside a building — control panels, detectors, notification appliances and communicators.
Federal occupational data counts the work inside the combined occupation “security and fire alarm systems installers,” and O*NET defines it as installing, programming, maintaining and repairing fire alarm wiring and equipment so it meets the relevant codes.
What is a fire alarm technician?
O*NET, the U.S. Department of Labor’s occupational database, defines the occupation that holds this title as workers who install, program, maintain and repair security and fire alarm wiring and equipment.
The occupation is security and fire alarm systems installers, SOC 49-2098, and its definition adds that workers ensure the work is in accordance with relevant codes.
Fire alarm technician is one of the job titles O*NET reports within that occupation, alongside alarm technician, installer, installation technician and service technician.
The same occupation also covers security and burglar alarm installers, so its federal figures are not a fire-alarm-only count.
BLS counted 86,340 jobs in the occupation nationally in May 2025.
NFPA 72, National Fire Alarm and Signaling Code, counts the people who do this work among its users.
NFPA lists “installation, inspection, testing, and maintenance service providers” alongside fire alarm designers, electrical contractors, fire protection engineers, AHJs, inspectors and plan reviewers, and it lists the 2025 edition as the current one.
The occupation also spans distinct kinds of work — new installation, service and troubleshooting on existing systems, scheduled inspection and testing, and programming.
The next section takes each in turn.
What does a fire alarm technician do each day (install, service, inspect, program)?
O*NET’s definition of the occupation — install, program, maintain and repair — covers four kinds of work a technician can spend a day on: installing wiring and devices, servicing systems that are not working right, inspecting and testing systems on a schedule, and programming.
On the installation side, O*NET’s task list for the occupation includes drilling holes for wiring in studs, joists, ceilings or floors, feeding cables through access holes, roof spaces or cavity walls, and mounting raceways and conduits.
Service and troubleshooting draws on the same list: testing and repairing circuits and sensors, examining systems to locate problems such as loose connections or broken insulation, and testing backup batteries and programming.
Periodic inspection and testing of existing fire alarm systems is a specialization of its own — NICET developed a separate credential for inspectors who specialize in that work — while programming is named in O*NET’s definition of the occupation alongside installing, maintaining and repairing.
It is physical work.
In O*NET work-context survey data for the occupation, 35% of workers said they spend about half their time climbing ladders, scaffolds or poles.
Schedules and on-call arrangements are set by the employer; our research did not establish typical rotation, overtime or drive-time patterns for this occupation.
Who hires fire alarm technicians?
BLS industry rows show where workers in the combined occupation are employed.
The rows do not separate fire alarm work from security alarm work, but they give a picture of the employer mix.
Investigation and security services — the industry that includes security-alarm companies — employed 55,920 of these workers in May 2025, at a median of $28.96 per hour ($60,240 per year).
It is the largest single industry row for the occupation in our extract of the data.
Electrical contractors (NAICS 238210, the row where most fire alarm contractors are classified) employed 14,820 workers at a median of $27.95 per hour ($58,130 per year).
Plumbing, heating and air-conditioning contractors (NAICS 238220, the row where sprinkler contractors are classified) employed 5,930 at a median of $29.97 per hour ($62,330 per year).
The broader building equipment contractors group (NAICS 238200) employed 20,830 at a median of $60,050.
Read against the fire protection industry, the rows cover security-alarm companies, the electrical contractors where most fire alarm contractors are classified, and the plumbing, heating and air-conditioning row where sprinkler contractors sit.
With the caveats above, that is the closest the federal data comes to an employer map for this trade.
What do you need to become a fire alarm technician?
BLS lists the typical entry requirements for the occupation as a high school diploma or equivalent, no prior work experience and moderate-term on-the-job training; 0.9% of workers were self-employed in 2025.
O*NET places the occupation in Job Zone Three, “medium preparation needed” — usually one or two years of training that combines on-the-job experience with informal learning from experienced workers.
There is a registered-apprenticeship route too.
O*NET lists “Fire Alarm Inspection Test Maintenance Technician” and “Protective-Signal Installer” as apprenticeship titles linked to this occupation that the U.S. Department of Labor has approved for use in a Registered Apprenticeship Program.
Time in a neighboring trade can count later.
NICET lets Fire Alarm Systems Level II–IV candidates count part of their required experience as related experience, which includes low voltage systems, building electrical power or control systems, special hazards systems and smoke control systems.
Check the rules where you work
Do fire alarm techs need a license or NICET?
Two different things get called requirements in this trade, and they are not interchangeable: a state or local license, which is legal permission to do the work, and a NICET certification, which pairs examinations with documented work history.
A NICET certification is not a license, and a license is not a NICET certification.
Licensing is set state by state, and local city or county rules can apply on top; the agency that administers the rules varies too.
Confirm the requirements that apply where you work directly with the licensing authority.
NICET’s Fire Alarm Systems (FAS) certification is aimed at technicians who do a combination of system layout, equipment selection, installation, acceptance testing, troubleshooting, servicing and technical sales.
It has four levels, I through IV.
NICET also offers a narrower Inspection and Testing of Fire Alarm Systems (ITFAS) credential, which covers periodic inspection and testing of existing systems and was developed for inspectors who specialize in that work.
Two details matter if you plan around the exams.
NICET says the current Fire Alarm Systems exams are based on the 2022 edition of NFPA 72, and that updated exams based on the 2025 edition will follow around mid-2027.
Each certification runs on three-year cycles documented with 90 Continuing Professional Development points.
How much do fire alarm technicians make?
Start with the label on the numbers: BLS counts fire alarm technicians and installers inside the combined occupation “security and fire alarm systems installers” (SOC 49-2098), so its figures are not a fire-alarm-only wage.
The national median wage in that occupation was $28.88 per hour, or $60,070 per year, in May 2025.
The spread is wide: in May 2025 the 10th percentile earned $38,800 a year, the 25th $47,820, the 75th $73,690 and the 90th $81,150.
For outlook, BLS projects employment in the occupation to grow 6.8% between 2025 and 2035, from 86.3 thousand to 92.1 thousand jobs, with 8,500 openings a year on average.
All-occupation growth over the same window is 3.5%.

What is the career path?
NICET’s Fire Alarm Systems levels give the trade a shared ladder, and each level pairs an exam with documented experience.
NICET describes its Level I holders as trainees and entry-level technicians who perform limited tasks under supervision, “learning, much like apprentices.”
Level I requires the Level I exam, supervisor verification of performance measures, and a minimum of 6 months of experience with fire detection and signaling systems.
Level II requires the Level I and II exams and at least 2 years of fire detection and signaling experience, of which at least 12 months must be fire alarm systems experience.
NICET describes Level II technicians as performing routine tasks under limited supervision.
Level III requires a minimum of 5 years of fire detection and signaling experience, including at least 45 months of fire alarm systems experience.
The 3 years beyond Level II must include field experience, team leadership and at least one year in a fire alarm systems technical management role.
NICET says Level III technicians work independently, produce fire alarm shop drawings, supervise Level I and II technicians and interact with AHJs.
Level IV requires a minimum of 10 years of fire detection and signaling experience, including at least 105 months of fire alarm systems experience, plus at least two years overseeing fire alarm project management, a personal recommendation and a written major project.
Those figures are NICET’s certification minimums, not a schedule; how quickly you climb depends on the work your employer gives you.
Every level is kept current on three-year cycles with 90 CPD points.
The ladder also branches.
NICET’s scope list for the Fire Alarm Systems certification names layout (plan preparation), equipment selection and technical sales alongside installation, acceptance testing, troubleshooting and servicing — design-side and sales-side work as well as hands-on service.
