Both are original practice written for Alarm Ladder. They are not NICET questions.

3 sample questions with answers

These are original practice items written for Alarm Ladder. They are not NICET questions, and they cite NFPA 72 by chapter only, so open your own copy to read the text. Give yourself about 85 seconds for each.

1. Supervising a circuit (Installation). A technician lands the end-of-line resistor on the first notification appliance of a two-wire circuit and leaves the last three appliances wired beyond it. What does the panel fail to supervise? Is it the first appliance, the wiring beyond the resistor, the panel's own output, or nothing, because the circuit still tests normal?

Answer: the wiring beyond the resistor. The end-of-line device lets the panel see an open anywhere between the panel and that device. Wire that continues past it is outside what the panel monitors, so a break there would leave appliances dead with no trouble signal, and the circuit would still look normal at the panel. The fix is to move the resistor to the last appliance. The first appliance is supervised either way, and the panel's output is not what the resistor checks. Look up the circuit and pathway supervision rules in NFPA 72 (2022) Chapter 12. The NAC vs SLC circuits guide shows how each circuit type is monitored.

2. Sizing a battery (Submittal preparation and system layout). A panel draws 0.40 A in standby and 1.8 A in alarm. The job calls for 24 hours of standby followed by 5 minutes of alarm, and the worksheet adds a 20% margin. Which is the smallest of these batteries that works: 7 Ah, 10 Ah, 12 Ah or 18 Ah?

Answer: 12 Ah. Standby is 0.40 A × 24 h = 9.60 Ah. Alarm is 1.8 A × (5 ÷ 60) h = 0.15 Ah. The total is 9.75 Ah, and the 20% margin makes it 11.70 Ah, so 12 Ah is the smallest that covers it. 10 Ah is the answer you get if you stop before the margin. 7 Ah is below even the 9.60 Ah standby draw, and 18 Ah works but is not the smallest. Secondary power sits in NFPA 72 (2022) Chapter 10. Try your own numbers in the battery calculator.

3. Taking a zone out of service (Maintenance). You will disable one floor's notification for about six hours of testing in an occupied building. What do you do before you start: begin and tell the owner afterward, tell the owner and the people responsible for the building and agree a plan, wait until the zone is quiet and skip the notice, or leave the zone enabled and test only the panel?

Answer: tell the owner and the people responsible for the building, and agree a plan. A planned shutdown that leaves part of the building without notification is an impairment, and the people who rely on the system need to know first, with a plan for the hours it is out. Telling the owner afterward is too late. Skipping the notice because the floor is quiet misses the point, since occupants are who the system protects. Testing the panel alone is not the job. Impairment handling is in NFPA 72 (2022) Chapter 10, and the testing and maintenance guide walks through a full test visit.

What Level II asks you to practice

Fire Alarm Systems Level II has 110 questions in 155 minutes, about 1.4 minutes an item. It is open book, and NICET gives you a built-in calculator, so personal calculators stay home. Practice under those conditions. The Level II exam guide covers the format, blueprint and a two-to-four-week plan, and the on-screen reference guide shows how the supplied references behave.

Your practice should cover four domains:

The calculation-heavy questions sit mostly in submittals and layout. Check your arithmetic with the battery calculator and voltage-drop calculator, and read the battery method and voltage drop formula guides to learn why each input is there. To practice finding chapters against the clock, try the free Level II lookup drill.

Turn every miss into a study task

A score tells you where you lost points. A short log tells you why. After each practice session, write one line per miss:

1. Domain and topic. Which of the four domains was it?
2. Miss type. Missing knowledge, slow lookup, calculation setup, or a misread instruction?
3. The fix. One sentence on what you will do differently, and one lesson or reference to revisit.

Fix the biggest group first. If most misses are slow lookups, drill navigation on the clock. If they are calculation setups, redo the worked example with new numbers. Do not repeat the same set until you remember the answers. A repeat score can reflect memory, not skill. Change the numbers, or explain each answer out loud before you look. To work one domain at a time, read Level II study by domain with a miss log.

Where Level II practice differs from Level I

Level I checks that you know the basics. Level II asks you to apply them on a job: sizing power supplies, reading drawings, writing up tests and leading the work. If you are still building the basics, start with the Level I practice guide. Then come back here. The level requirements guide explains the experience each level needs.

Ready to find your weak domain?

Start the free 10-question Level II check and see your score by domain. Ten questions are a small sample, so a good result is a starting point and not a prediction of your exam result. The Alarm Ladder course then drills your weak domains with timed practice and an explained answer for every question. For fees and retake rules, use the exam fees guide and the testing locations and rules guide.

FAQ

How many questions are on the NICET Level II exam, and how long do you get?

Fire Alarm Systems Level II has 110 questions in 155 minutes, about 1.4 minutes an item. Practice at that pace.

Is the Level II exam open book?

Yes. NICET supplies the references on screen and a built-in calculator, and personal calculators stay home. Practice finding a topic against the clock, not only knowing it.

Is there a free NICET Level 2 practice test PDF?

Yes. Print our free NICET Level II practice quiz (PDF): original questions with an answer key on page 2, and no email. Then take the free 10-question Level II check to see your score by domain.

How is Level II practice different from Level I?

Level I checks that you know the basics. Level II asks you to apply them on a job: sizing power supplies, reading drawings, writing up tests and leading the work. The questions above lean that way.

Where do our practice questions come from?

Every question is original and written to NICET's published outline. We do not reproduce NFPA 72 text.
