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

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

===========

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

===========

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

Animpairmentoccurs when part of the life safety system isdisabled or rendered ineffective. Aclosed sprinkler valvedirectly disables part of the fire suppression system, which meets the definition of an impairment.

NFPA 72 (2022), Section 3.3.149 — Impairment:

“A condition where a fire protection or life safety system or portion thereof is out of service.”

Smoke detector placement issues may be acode violationbut not a systemimpairment.Intelligible audibilityis a positive attribute, not a problem.

Correct answer: A. Closed sprinkler valve

===========

Elevator recall typically generates analarm signal, but under specific circumstances, theAHJ may approve the use of a supervisory signalinstead.

NFPA 72 (2022), Section 21.3.3.3 (Exception):

“Where permitted by the AHJ, activation of elevator recall initiating devices shall be permitted to result in a supervisory signal.”

This allows flexibilitywith AHJ approval, not at the discretion of designers or owners.

Correct answer: A. Where approved by the authority having jurisdiction
