ITFAS-Level-1 NICET Inspection and Testing of Fire Alarm Systems Level I Exam Free Practice Exam Questions (2025 Updated)

Manual fire alarm boxes (pull stations) must bevisually inspected monthlyto ensure accessibility, visibility, and no physical damage.

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

"Manual fire alarm boxes"→Monthly

The inspection verifies the handle is not blocked and the device is clearly labeled.

Correct answer: A. Monthly

===========

Room temperature switches are used to detectfreezing conditionsin environments such as sprinkler valve rooms. An off-normal (supervisory) condition is triggered if the temperature dropsbelow 40 °F (4.4 °C).

NFPA 72 (2022), Section A.17.16.1.1:

“Low-temperature supervisory signals shall be initiated when the temperature falls below 40 °F (4.4 °C) unless otherwise specified.”

This signal helps prevent system damage or failure due to freezing.

Correct answer: B. 40 °F (4.4 °C)

===========

NFPA 72 identifies severaltypes of fire alarm control units (FACUs)based on their function and scope.

NFPA 72 (2022), Section 3.3.103 — Fire Alarm Control Unit (FACU):

Dedicated Function FACU: Performs a specific fire alarm role (e.g., elevator recall or sprinkler monitoring).

Protected Premises FACU: Installed on-site to monitor and signal within that building.

Releasing Service FACU: Activates fire suppression systems like gas or foam.

"Central station" is asupervising station, not a control unit.

Correct answers:

Dedicated function

Protected premises

Releasing service

===========

Whensite-specific software(such as logic for fire alarm control panels) is changed,100% of the devices affectedby that change must be tested to confirm correct operation. Also,10% of unaffected devicesmust be tested as a safeguard.

NFPA 72 (2022), Section 14.4.2.2.4:

“When system software is modified, 100% of the affected devices or functions and 10% of the nonaffected devices or functions shall be tested.”

This ensures that updates don’t unintentionally compromise unrelated areas of the system.

Correct answer: D. 100% of devices affected
