A fire alarm technician installs, programs, tests, and repairs the systems that detect fire and get people out safely. You will pull cable, mount devices, program panels, and test everything to the codes your local authority enforces, mainly NFPA 72 (the National Fire Alarm and Signaling Code) and NFPA 70 (the NEC, Articles 760 and 725). You don't need a degree. About half of workers have a post-secondary certificate and the rest have a high school diploma. This roadmap teaches you the why before the how: basic electricity, then reading plans, then how a fire alarm loop works, then code, then

Stage 1 of 4 · about 8 weeks
Learn DC and AC basics, Ohm's law, reading a multimeter, basic hand and power tool safety, and the idea behind a fire alarm system: initiating devices, notification appliances, and a control panel. Practice by building a simple 9V battery circuit with a switch and buzzer, and by measuring voltage, continuity, and resistance on household items.
DC and AC electrical basics with Ohm's law
Every fire alarm panel runs on low-voltage DC (usually 24V) and is powered from 120V AC with a battery backup. If you understand voltage, current, and resistance, wiring faults stop being mysterious and become simple math you can reason through on the job.
Using a multimeter
The multimeter is the tool you will reach for on almost every service call. It tells you if a circuit has power, if a wire is broken, and if a device is the right value. Using it safely and correctly is the first real skill of the trade.
Hand tool, power tool, and electrical safety
Installers drill through studs, climb ladders, strip wire, and work near live circuits all day. Good habits keep you uninjured and employable, and employers watch for them in the first week.
How a fire alarm system works
Before you wire anything, you need the big picture. When you know what each part is for, you can trace problems, follow drawings, and talk with confidence in an interview.
