Pass the NICET Inspection and Testing of Fire Alarm Systems ITFAS-Level-1 Questions and answers with ValidTests

During avisual battery inspection, the technician checks forcorrosion, leakage, swelling, andloose or corroded terminals— not electrical readings (those are part of functional testing).

NFPA 72 (2022), Table 14.3.1 — Inspection Frequencies:

“Batteries (lead-acid and nickel-cadmium)” → Visual inspection items include:

Cleanliness

Terminal tightness

Corrosion or leakage

Physical damage

Voltage and charging checks are part oftesting, not visual inspection.

Correct answers:

Check for corrosion or leakage

Check tightness of connections

===========

Testing of engine-driven generators is governed byNFPA 110, not NFPA 72. NFPA 72 references this standard for standby power systems.

NFPA 110 (2022), Section 8.4.1:

“Diesel generator sets shall be exercised at least once weekly.”

This includes running the generator under load and verifying automatic start capability.

NFPA 72 (2022), Section 10.6.3.2:

Refers to NFPA 110 for testing of standby/emergency power systems.

Correct answer: A. Weekly

===========

NFPA 72 requires annual testing to ensuretrouble signalsare correctly transmitted to the off-premises monitoring location (e.g., central station).

NFPA 72 (2022), Table 14.4.3.2 – Testing Frequencies and Methods:

Under “Off-Premises Transmission Equipment,”trouble signalsare testedannually.

This ensures that the system will properly report malfunctions.

Correct answer: D. Annually

Asupervisory signalindicates a condition thatrequires attention but is not an alarm. In sprinkler systems, one of the most common supervisory signals comes from avalve tamper switch, indicating a partially closed valve, or sometimes awaterflow switch resetissue.

NFPA 72 (2022), Section 3.3.269:

"Supervisory Signal — A signal indicating the need for action in connection with the supervision of guard tours, the fire suppression systems, or equipment or maintenance features of related systems."

Also:Table A.10.14.2.1

Shows thatwaterflow valves and tamper switchesare typical sources of supervisory signals.

So the correct answer — awaterflow alarmimplies something abnormal with the fire protection system, possibly indicating a tamper switch or system supervisory issue.

Correct answer: D. A waterflow alarm has been activated

===========

Before performing any inspection or testing activities, it's critical tonotify all affected parties, including occupants, central stations, and local authorities (as applicable), toprevent accidental dispatch of emergency services. The reason for this is clearly stated inNFPA 72 (2022 Edition), Section 14.2.3.1, which requires notification of all stakeholders before any test.

NFPA 72:2022 – 14.2.3.1

"Prior to any testing,all persons and facilities receiving alarm, supervisory, or trouble signals, and allbuilding occupantsshall benotifiedto preventunnecessary response."

This is critical for avoiding disruptions like fire department rollouts or building evacuations that could be triggered by system activations during a test. That makes the correct answer:

D. Unnecessary response

Thefunctional test of the primary power supplyensures that the fire alarm system responds properly to a loss of power and transitions to secondary power.

NFPA 72 (2022), Table 14.4.3.2 — Test Methods and Frequencies:

Primary power supply is required to be testedannually, which equates toevery 12 months.

Correct answer: D. Every 12 months

===========

NFPA 72 places amaximum allowable sound pressure levelto prevent hearing damage or discomfort in occupied areas.

NFPA 72 (2022), Section 18.4.1.5:

“The total sound pressure level produced by the fire alarm system, including ambient noise, shall not exceed 105 dBA at the minimum hearing distance from the audible appliance.”

This ensures alarm audibilitywithout causing harm.

Correct answer: B. 105 dBA

===========

Amaster boxis a type of manual fire alarm box connected directly to a public emergency reporting system (typically a municipal or fire department network). NFPA 72 requires these to be testedannuallyto ensure they still properly send signals to the public system.

NFPA 72 (2022), Table 14.4.3.2 — Inspection, Testing, and Maintenance Frequencies:

UnderPublic Emergency Alarm Reporting Systems→Master Boxes:

Test Frequency:Annually

Method:"Manual operation and verification of signal receipt at the public communication center."

The test confirms the box functions mechanically and that the signal is received by the appropriate monitoring point (e.g., fire department dispatch).

Correct answer: D. Annually

===========

NFPA 72 mandates astandardized evacuation signal patternto ensure building occupants can recognize and respond to an emergency.

NFPA 72 (2022), Section 18.4.2.1:

“Where audible appliances are used for evacuation or relocation, the alarm signal shall be the Temporal-Three Evacuation Signal pattern (three short audible signals followed by a pause).”

This pattern is commonly known as theTemporal-3orT-3signal.

Correct answer: C. Provides a 3-pulse temporal pattern

===========

NFPA 72 requiressound pressure level measurementsto verify that audibility meets code requirements. This must be done duringinitial acceptanceandreacceptance testing(e.g., when system changes occur).

NFPA 72 (2022), Section 18.4.7.2:

"Sound pressure level measurements shall be taken and documented during acceptance and reacceptance testing."

Correct answer: B. Sound pressure levels are required to be taken during initial acceptance and reacceptance testing.
