All ITFAS-Level-1 Test Inside NICET Questions

Signal priorities determine the order in which events are processed and displayed by the fire alarm system.

NFPA 72 (2022), Annex A.10.14.3 and system programming guidelines:

While not directly listed in a table, systems are programmed such that:

Alarm (including pre-alarm)has the highest priority

Followed bysupervisory, thentrouble, and finallyrestoral

Pre-alarm is part ofalarm initiation logicand is treated as high-priority due to its potential escalation.

Correct answer: A. Pre-alarm

Replacement batteries used in fire alarm systems must meet strict safety and documentation requirements:

NFPA 72 (2022), Section 10.6.10.1.2:

“Batteries shall be marked with the month and year of manufacture.”

NFPA 72 (2022), Section 10.6.10.2:

“Batteries shall be listed for the intended purpose by a nationally recognized testing laboratory (NRTL).”

There isno requirementthat replacement batteries must be the same make/model, though compatibility must be ensured.

Correct answers:

Batteries shall be listed by a nationally recognized testing laboratory

Batteries shall be marked with the month and year of manufacture

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

Control valve supervisory switches must be tested to verify that they send a signal when the valve position changes (e.g., valve is closed). NFPA 72 requires this to be doneannually.

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

Control valve supervisory switch:

Frequency:Annually

Method:Operate valve control; verify signal annunciation.

Correct answer: D. Annually
