NICET I&T Fire Alarm Level II exam: interfaces are half the test

Check your route into I&T Level II

The exam facts and blueprint below give the question count, time, fee, domain weights, reference editions and experience requirements. Read the testing locations and rules before booking. Remote delivery for this program is limited to Level I, so plan on a test center for Level II.

Level II certification also needs the Level I exam, or exam credit for it. NICET's ITFAS candidate handbook (p. 9) lets candidates apply for credit once they have met the FAS Level II exam requirement. Candidates meeting FAS Level III or IV exam requirements can apply for I&T exam credit and cannot sit I&T Level I or II exams. Credit doesn't award certification by itself. You still need verified performance measures and qualifying experience, including the required complex-system experience in the period beyond Level I, with limits on other experience categories, so don't count all your installation time. If you have neither the exam nor the credit yet, start with our Inspection and Testing Level I exam guide. Still choosing a track? See how Inspection and Testing compares with Fire Alarm Systems.

Use the I&T reference list, not the FAS list. NFPA 72 and NFPA 92 are on screen during the exam, and the on-screen reference routine shows how to move between codes quickly.

What each I&T Level II domain asks you to do on the job

Plan and coordinate work. NICET covers assignment scope, site information, documentation, other building systems and coordination with affected parties. Build a test plan from permitted drawings and a sequence of operations. Name the participants, access needs and how results will be recorded, and list unresolved documentation gaps before you choose a sequence.

Inspect interfaces and specialty equipment. The outline includes elevators, smoke control, suppression interfaces, emergency communications, specialized detection and networked controls. Trace each interface from the fire alarm equipment to the connected system and list the equipment and documents to inspect. Keep observations separate from functional results, because finding a connection doesn't show that it operates.

Test functionality of specialized and interfaced equipment. This is the heaviest domain. NICET includes interface operation, detector sensitivity, complex notification and completion records. For an authorized training exercise, describe the initiating action, expected response, observation and restoration, and rotate through networked equipment and emergency communications. The testing and maintenance guide helps you organize the record.

Interfaces and measurements: where this exam differs

Keep measurement and interpretation together. On a practice record, name the instrument, the measured quantity, the unit and the manufacturer instructions used to read it. Don't swap functional activation in for sensitivity measurement, because the outline lists sensitivity as its own task. Record the code section you used to choose the method.

For smoke control, include both listed references and return to the source after you read the other document. Start from the interface task in the outline, use its reference footnotes to choose the publication, then find and record the section number in your own copy.

Elevator recall and shutdown behavior partly comes from ASME A17.1, which isn't on NICET's I&T reference list. The available NFPA references don't cover the full elevator sequence, so study the fire alarm interface next to the documented elevator sequence and settle who is responsible for what before you plan a test. NFPA's committee record, linked below, documents that cross-code relationship.

Power questions still appear in review. Work an assignment with stated durations: standby A × 24 h plus full alarm A × (5 or 15 min ÷ 60), then the assigned margin and the next compatible battery size. The battery calculation method and battery calculator cover it. A capacity rating alone doesn't establish battery condition or prove interface operation. For NAC loading, the voltage drop formula guide and voltage-drop calculator cover the method. Use the current for each selected output setting, and keep NAC and SLC straight with NAC vs SLC circuits before you interpret a fault response.

Watch the track, too. Don't substitute the FAS reference pair, and don't assume an FAS edition-change announcement applies to I&T. Check this program's current reference list.

References you can use

NICET publishes a Selected General References list for each ITFAS level, and you should use only the list for your own level. Check NICET's references page for the current Level II list. Use the Level II list, not the FAS list and not Level I's. For comparison, the Level I list names one title, NFPA 72, 2022 edition, and the exam shows it on screen as a PDF. Level II adds NFPA 92 for smoke control, as covered above. Read the editions on NICET's current Level II list before you buy or print anything, because questions are written to the listed editions.

If you bring a printed copy, check NICET's binding and tab rules for your level first. The Level I list allows highlighting and permanently attached tabs, and it does not accept handwritten notes, loose pages or an NFPA Handbook in place of the code. Confirm Level II says the same before you prepare a book. Practice on a digital copy too.

Don't expect the references to answer every question. As noted above, elevator recall draws on ASME A17.1, which is not on NICET's list. Find each outline task in your own copy and note the section number yourself.

A two-to-four-week plan led by the free check

Take the free 10-question I&T Level II check. Sort misses by domain and interface, then decide whether each was knowledge, navigation, calculation or reading.

• Week 1: focus on your weakest interface group. Trace its documentation and write inspection evidence and functional-test evidence separately.
• Week 2: rotate through the other interfaces, planning and close-out. Practice switching between references and explaining who restores what.
• Weeks 3 to 4, if needed: revisit recurring errors with fresh permitted examples. Mix interface types and timed lookups.

Find your weakest interface group now: take the free 10-question I&T Level II check for a score by domain with no signup. The Alarm Ladder course then drills those domains with original questions and explanations that cite the section.

After Level II

Certification lasts three years. To keep it you earn 90 continuing professional development points per certification in each cycle, drawn from at least two categories, and every later NICET certification expires on the same date as your first (handbook, p. 8). Our renewal guide covers the points in more detail.

The ITFAS candidate handbook does not set out Level III requirements, so check NICET's own ITFAS program page for them. Whatever they are, keep your verified performance measures and a dated work history from the start. Our work history guide shows how to describe the time you claim. NICET alone decides eligibility and exam results.
