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

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

===========

Heat detectors that arenonrestorablemust either be replaced after 15 years or undergo sample testing. If testing is chosen,at least 4 detectors per 100of the same model and environment must be tested in an approved lab.

NFPA 72 (2022), Section 14.4.4.4.1:

“After 15 years from the date of installation, all fixed-temperature, nonrestorable heat detectors shall be replaced or tested using a laboratory method... A minimum of 4 detectors shall be tested for each 100 detectors installed.”

This ensures detector reliability over time.

Correct answer: B. 4

===========

Testing of engine-driven generators is governed byNFPA 110, not NFPA 72. NFPA 72 references this standard for standby power systems.

NFPA 110 (2022), Section 8.4.1:

“Diesel generator sets shall be exercised at least once weekly.”

This includes running the generator under load and verifying automatic start capability.

NFPA 72 (2022), Section 10.6.3.2:

Refers to NFPA 110 for testing of standby/emergency power systems.

Correct answer: A. Weekly

===========

NFPA requiresdaily visual inspectionof fire alarm control equipment if it isnot monitored(not connected to a supervising station). This is to manually check for trouble lights, alarms, or other fault indications.

NFPA 72 (2022), Table 14.3.1 — Control Equipment (not monitored):

Visual inspection frequency: Daily

Correct answer: A. Daily

===========

In aClass Afire alarm circuit, asingle opencondition does not affect communication but must still be annunciated as atroublesignal.

NFPA 72 (2022), Section 12.3.1.1.1.4:

“A single open condition on a Class A pathway shall result in a trouble signal.”

This maintains system operation while alerting of a wiring fault.

Correct answer: D. Trouble

===========

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

Fire alarm systems that communicate via telephone lines are required to monitor those lines for disconnection. If theprimary line fails, it must be reported as asupervisory condition, and the system will attempt communication via thesecondary line.

NFPA 72 (2022), Section 26.6.4.4.4.1:

"A single communications technology shall be monitored for integrity. Loss of the supervising line shall result in a supervisory signal..."

So, if theprimary phone line is disconnected, the correct system response is to issue asupervisory signal, not a general alarm or just a local alert.

Correct answer: D. Supervisory condition
