NICET Inspection and Testing Level 1 Practice Test

Start with the free practice

• Take the free 10-question I&T Level I check. It takes a few minutes, needs no signup and no card, and is weighted to the four Level I domains. It shows your score with your weakest domain named, and every answer is explained.
• Work the free I&T Level I sample set. It has 10 practice questions across the four domains and a short lesson on testing a smoke detector, with the answers explained as you go.

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

5 sample questions with answers

These are original practice items written for Alarm Ladder. They are not NICET questions, and they quote no code text. Each answer points to the NFPA 72 (2022) section to read in your own copy. At 85 questions in 110 minutes, give yourself about 78 seconds for each.

1. A finding you cannot fix today (Plan and coordinate work). During the annual test you find that every notification appliance on the third floor stays silent and dark in alarm, and the parts to repair the circuit will not arrive until next week. What do you do before you leave: list it in the report the office mails out next week, tell the owner or building manager now and record it as a deficiency, tell only the monitoring company, or reset the panel so the trouble clears?

Answer: tell the owner or building manager now and record it as a deficiency. A floor with no alarm signal leaves people there without warning, so the person responsible for the building has to know before you walk away, and the record has to show it. A report that arrives next week leaves the owner in the dark until then. The monitoring company receives signals but does not run the building. Resetting the panel hides the problem without fixing it. Read NFPA 72 (2022) Section 14.2 for the general rules on deficiencies and Section 14.6 for records.

2. Paint on a strobe (Inspect equipment). After a repaint, you find a strobe in a corridor with a coat of wall paint over its lens. It still flashes when you look closely. How do you report it: as acceptable, since it still flashes; as a cosmetic note for the next visit; as a deficiency, since paint on the lens can cut the light it puts out; or as acceptable, if the horn in the same unit still sounds?

Answer: as a deficiency, since paint on the lens can cut the light it puts out. A visible appliance has to deliver its signal, and paint over the lens changes what reaches the room. Seeing a faint flash up close does not show it still does that job across the space. Calling it cosmetic leaves a weakened appliance in service. A working horn does nothing for the people who rely on the visible signal. Read Section 14.3 for visual inspection and Chapter 18 for notification appliances.

3. A heat detector that cannot be reset (Test functionality). The device list shows several non-restorable fixed-temperature spot heat detectors in a storage room. How do you functionally test them: heat each one until it alarms, test each one mechanically and electrically without heating it, skip them because they cannot be tested, or replace each one with a smoke detector?

Answer: test each one mechanically and electrically without heating it. A non-restorable detector is destroyed when its element operates, so heating it would use it up. Testing it mechanically and electrically checks the device and its circuit and leaves it in service. Skipping the devices leaves part of the system unproven. Swapping in a smoke detector changes the design and is not a test. Read Section 14.4 for test methods and Chapter 17 for initiating devices.

4. Pulling a battery lead (Test functionality). As part of the power supply test, you disconnect one lead of the control unit's standby battery. Which result is a pass: the panel shows nothing because primary power is still on, the panel goes into alarm, the panel shows a trouble signal, or the panel shuts down?

Answer: the panel shows a trouble signal. The control unit watches its secondary power source, so losing the battery should be announced as a trouble even while primary power is on. A panel that shows nothing would leave a missing battery unnoticed until the next power cut. An alarm is the wrong kind of signal for a power fault. A shutdown would mean the panel is not running on primary power at all. Read Chapter 10 for power supplies and Section 14.4 for testing.

5. A dusty smoke detector (Maintain devices). A smoke detector in a dusty workshop keeps reporting that it needs cleaning. What is the right fix: blow it out and put it back without testing, clean it the way the manufacturer's published instructions say and then test it, disconnect it until the workshop closes, or swap it for a heat detector?

Answer: clean it the way the manufacturer's published instructions say and then test it. Cleaning follows the maker's method for that model, and a test afterward shows the detector senses and reports again. Putting it back untested leaves you guessing. Disconnecting it takes protection away from the room. A heat detector is a different device type, which is a design change. Read Section 14.5 for maintenance and Section 14.4 for the test after it.

What I&T Level I asks you to practice

Inspection and Testing Level I has 85 questions in 110 minutes. NFPA 72 (2022) is on screen as a PDF, and you may also bring a printed copy that follows NICET's binding and tab rules. Both a basic and a scientific calculator are built into the exam, so personal calculators stay home. The I&T Level I exam guide covers experience, fees, references and the credit from Fire Alarm Systems Level II.

NICET's content outline splits the exam into four domains. Sort your practice the same way:

Testing functionality is about half the exam, so give it the most sessions. Level I covers basic systems only. The outline leaves out suppression systems, networked control units, smoke control, air sampling, multizone voice evacuation, high-rise applications and job planning, which Level II picks up. Door releases, elevator recall, duct detectors and fan shutdown outside smoke control can still appear.

Review your misses by domain

When you get a question wrong, write one line with the domain, the outline task and what went wrong:

• Coordination. You missed who needed to know, or you left before the system was back to normal.
• Inspection. You called a deficiency acceptable, or looked at the wrong part.
• Test method. You picked a method that does not prove the device works, or that destroys it.
• Expected result. You expected an alarm where a trouble belongs, or the other way round.
• Records. Your note would not tell the next technician what you found and what you did.

Then find the section in your own NFPA 72 and write its number beside the miss. Doing that every time builds the lookup speed the open-book exam rewards. The testing and maintenance guide and NAC vs SLC circuits help with the most common test-method misses.

Do not repeat a set until you remember the answers. Change the scenario, or explain the test out loud before you check. NICET also offers online practice tests for every Inspection and Testing level, and its handbook says your score on them is not necessarily an accurate guide to how you will do on the exam. Treat any practice score as a map of what to study next.

Ready to find your weak domain?

Take the free 10-question check and see your score and your weakest 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. Planning ahead? The I&T Level II practice test guide shows how the interfaces grow at the next level, and the free 10-question I&T Level II check scores you by domain without a signup.

FAQ

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

It has 85 questions in 110 minutes, a little under 78 seconds a question.

Is the I&T Level I exam open book?

Yes. NFPA 72 (2022) is on screen as a PDF, and you may bring a printed copy that meets NICET's reference rules. A basic and a scientific calculator are built in, so personal calculators stay home.

Does a practice test score predict your I&T Level I result?

No practice score can promise a result. NICET's own handbook says its practice test scores are not necessarily an accurate guide to exam performance. Use a score to pick the domain you study next.

Where do our practice questions come from?

Every question is original and written to NICET's published outline.
