ITFAS-Level-1 Exam Dumps - Inspection and Testing of Fire Alarm Systems Level I Exam

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.

Amultimeteris the standard tool used by fire alarm technicians to measure bothbattery voltageandcharging current.

NFPA 72 (2022), Table 14.4.3.2 – Testing Methods for Batteries:

Testing includes checking the voltage and current — commonly done using a multimeter.

Multimeters are capable of readingDC voltage(for battery levels) andamperage(for charge current).

Normally, smoke detector sensitivity testing is requiredevery two years, butNFPA 72 allows extension up to five yearsif thedetectors have not experienced frequent nuisance alarmsand accuraterecords of performanceare maintained.

NFPA 72 (2022), Section 14.4.4.3.2:

“Where detectors are cleaned and maintained and where records of nuisance alarms and changes in detector locations are kept, the sensitivity testing interval shall be permitted to be extended to 5 years.”

Keeping a log of nuisance alarms helps assess the reliability of the detectors over time.

Correct answer: C. Records of nuisance alarms shall be maintained

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

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.

Candela ratings arevisually confirmedduringinitial acceptance. Further inspection is requiredonly if a device malfunction occursor areacceptance testis performed.

NFPA 72 (2022), Section 18.5.5.7:

“The candela rating shall be verified at initial acceptance and when there is reason to believe the device is not operating properly.”

Visible notification appliances (strobes) must flash at aminimum rate of one flash per secondto meet visibility and perceptibility requirements.

NFPA 72 (2022), Section 18.5.3.4.1:

“The flash rate shall be not less than 1 flash per second and not more than 2 flashes per second.”

Correct answer: A. 1

===========

Radio transmitters used in fire alarm systems for off-premises signal transmission must be inspected to verify physical condition, connections, and proper operation. The requiredinspection interval is quarterly.

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

"Radio transmitters" → Frequency: Quarterly

Correct answer: B. Quarterly
