The control unit, alarm vs. supervisory vs. trouble, battery calculations, smoke and heat detectors, horns and strobes, Class A vs. Class B, supervising stations and elevator recall: in the code, it's a wall of text. Here each topic fits on one page, with the drawing and what you need to remember. 65 illustrated pages.

One topic per page, the drawing that shows you how it's done and the boxes with what you need to know:

These are real pages from the book. The table of contents is the full one: 11 parts and 61 topics.
You've silenced and reset hundreds of panels. Then a practice question asks if a closed valve is supervisory or trouble, and you read the battery section three times...
...and you still second-guess the signal and leave the battery math half done. In the code it's just lines of text, one after another.

Here the control unit is a single page, cut open: 8 labeled parts, with acknowledge, silence and reset explained right beside them.
And on the pages next to it, every system gets its own: the batteries, the initiating circuit with its end-of-line resistor, the pull station, the horns and strobes, and the supervising station.
First you understand why it works that way. Then the order sticks on its own.

Your NICET exams, planning the work, control units and power, initiating devices, notification appliances, circuits and wiring, off-premises signaling, basic interfaces, Level II systems, maintenance and documentation, and final review: 65 pages, all drawn.
Imagine this:
Instead of rereading half a page about Class A and Class B pathways without being able to picture them...
...you open the page and find both circuits drawn side by side, with the end-of-line resistor right where it goes and the Class A pathway running back to the panel.

And the control unit, the battery calculation, smoke detectors, strobes and elevator recall turn into drawings and tables you can read at a glance.
You stop repeating and start understanding.
That's exactly what The Fire Alarm Inspection Sketchbook does. It's not “just another manual.” It's 11 parts and 61 drawn topics, and at the end the most frequent mix-ups side by side and an exam day checklist. Because what your brain sees in order, it remembers.
Because what your brain sees organized, it remembers.
What Level I and Level II cover, how to find answers fast in NFPA 72 during the exam, and the whole system in one drawing.
The paperwork before you start, who to notify, inspection vs. testing vs. maintenance, where to look up frequencies, impairments and the test form.
The control unit panel by panel, alarm, supervisory and trouble, primary power, batteries, the battery calculation step by step and battery testing.
Pull stations, ionization vs. photoelectric smoke detectors, heat detectors, duct and beam detectors, waterflow and tamper switches, and sensitivity testing.
Horns, speakers and strobes, measuring audibility, candela ratings, temporal-three, synchronized strobes and single-zone voice.
IDCs and end-of-line resistors, NACs, SLCs and addressable devices, Class A vs. Class B, opens, shorts and ground faults, and inspecting wiring.
The three types of supervising station, communicators and transmission paths, and testing the signal to the monitoring station.
Door holders and releases, elevator recall, shunt trip and firefighter light, air handler shutdown and sprinkler supervision.
Suppression releasing, pre-action and deluge, smoke control, air sampling, networked panels, multi-zone voice and mass notification, firefighter phones, ERCES, high-rise systems and surveying a complex system.
Cleaning and replacing devices, compatible listed replacements, deficiencies vs. impairments, and the record of completion and test reports.
The most frequent mix-ups side by side, an exam day checklist and what comes after Level II.
At the end of the book: The most frequent mix-ups side by side and an exam day checklist.

40 exam-style problems on battery sizing, end-of-line resistors, Class A vs. Class B pathways and fault conditions, each one worked step by step so you can see exactly where your math went off.

Printable cards with the term on the front and a one-line definition plus a tiny sketch on the back, for reviewing in short sessions between jobs.

Fire alarm technicians and inspectors preparing for NICET Inspection and Testing of Fire Alarm Systems Level I or Level II, sprinkler techs adding fire alarm, electricians moving into fire alarm, and anyone retaking the exam. It's not the design and installation program. Check the index above for every topic.
The NICET ITFAS Level I and Level II content outlines and exam information (exams updated October 7, 2024, nicet.org), checked against the NFPA 72 edition on NICET's reference list for each level. The book doesn't copy code text: it shows you where to look. Exam details can change, so always check nicet.org.
No. It's an independent study guide. It is not affiliated with or endorsed by NICET, NFPA or any authority having jurisdiction. It doesn't give you a certificate or credits, and it doesn't count toward NICET work experience: it helps you study for the exam.
No. You still need the NFPA 72 edition your exam references, your company's training, the manufacturer's instructions and your AHJ's requirements. The book helps you understand each system and know which chapter to open, so you spend less time searching.
No. The 40 problems in the workbook are exam-style questions written for this book. They're not official NICET questions: they're there to help you practice.
Yes. The PDF is made to print, so you can keep pages on your clipboard or in the truck.
You have 30 days. Tell us what didn't work and we'll refund 100%.
You don't have to reread the same page hoping this time it sticks.
You don't have to memorize circuits and signals you can't picture.
And you definitely don't have to walk into the exam not knowing where to start.
There's a simpler way. And it's one click away. Now it's your turn.
