ITFAS-Level-1 Exam Dumps - NICET Inspection and Testing of Fire Alarm Systems Questions and Answers

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

===========

NFPA 72 sets a maximum time limit for verifying that signals frominitiating devicesreach thesupervising stationduring testing. The purpose is to ensure that communication paths and processing do not introduce unsafe delays.

NFPA 72 (2022), Section 14.4.3.4.2:

"Where connected to a supervising station, the signal shall be confirmed as received at the supervising station within 90 seconds of initiating device activation."

Correct answer: C. 90 seconds

===========

NFPA 72 requiresaudible and visible indicationsoftrouble conditionsto be presentat the fire alarm control unitand ata constantly attended location, such as anemergency command center.

NFPA 72 (2022), Section 10.14.2:

“Trouble signals shall be indicated visually and audibly at the protected premises at the fire alarm control unit and at a location where personnel are present 24 hours a day.”

In many buildings, that location is anemergency command center.

Correct answer: Emergency command center, Fire alarm control unit

===========

DACTs (Digital Alarm Communicator Transmitters) are required to supervise their telephone communication paths. If theprimary line is disconnected, the system must detect and transmit a trouble signal quickly.

NFPA 72 (2022), Section 26.6.4.4.4.2.3:

“Loss of the primary means of transmission shall be annunciated at the protected premises within 4 minutes.”

This ensures prompt identification and correction of communication issues.

Correct answer: C. 4

This is a documentation requirement, and it’s found inChapter 14of NFPA 72, which deals withInspection, Testing, and Maintenance.

NFPA 72 (2022), Section 14.6.3.1:

"Records shall be retained for a period of one year after the next test and until the next test is performed. Records shall be made available to the authority having jurisdiction upon request."

Section14.6.3lays out theformat, retention, and content requirementsfor inspection, testing, and maintenance records.

Correct answer: D. 14.6.3

Tip: For questions involvingrecordkeeping, head straight toChapter 14, especially section14.6.

===========

Transmitters connected tosupervising stations(such as DACTs or IP communicators) must be inspectedquarterlyto ensure signal integrity and physical condition.

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

"Supervising station transmitting equipment"→Quarterly

This includes checking for damage, loose connections, or communication issues.

Correct answer: B. Quarterly

===========

Emergency voice/alarm communication systems must continue functioning after a loss of primary power for aminimum of 24 hours in standby, followed by15 minutes of alarmoperation.

NFPA 72 (2022), Section 10.6.7.2.1.1 (Exception):

“…followed by 15 minutes of alarm for emergency voice/alarm communication systems.”

This ensures that occupants can still hear evacuation messages even during a power outage.

Correct answer: D. Minimum of 15 minutes

===========

NFPA 72 sets a maximumhorizontal travel distancebetween manual pull stations (manual fire alarm boxes) to ensure accessibility in large spaces.

NFPA 72 (2022), Section 17.14.6.4:

“The maximum travel distance to a manual fire alarm box shall not exceed 200 ft (61 m).”

This is for accessibility so occupants can reach a pull station quickly in an emergency.

Correct answer: D. 200 feet (61 meters)

===========

Inspection intervals are detailed inNFPA 72, Table 14.3.1, which outlines the maximum intervals for various components. Most fire alarm system components require inspectionat least annually, which equals12 months.

NFPA 72 (2022), Table 14.3.1 – Frequency of Inspection Tasks:

You’ll see that the default maximum inspection interval for initiating devices, control equipment, and notification appliances is12 months.

Unless specifically stated otherwise (e.g., by manufacturer instructions or performance-based design), you cannot exceed that.

Correct answer: C. 12 months

===========

Projected beam smoke detectors are testednot with actual smoke, but by simulating obscuration usinglisted toolssuch as atest switchoroptical filter.

NFPA 72 (2022), Section 14.4.2.2.6.2:

“Projected beam-type smoke detectors shall be tested by introducing an obscuration in the beam path using an optical density filter or a method approved by the manufacturer.”

Some systems includelisted test switchesfor functional checks without disrupting alignment.

Correct answer: Using a listed test switch, Using an optical filter

===========
