If you choosenot to send a sample of devices to a lab for testing, thenall nonrestorable, fixed- temperature spot-type heat detectorsmust be replaced after 15 years.
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 method approved by the manufacturer." If testing isnot performed, thenreplacement of all devices is required.
Correct answer: D. Replace all devices

When a fire alarm system isimpacted for any period of time, certain parties must be notified bothbeforeand aftertesting or impairment. When the impairment isless than 8 hours,NFPA 72 (2022), Section 10.21.3.6 applies.
NFPA 72 (2022), Section 10.21.3.6:
"Where a system has been impaired for less than 8 hours, notification shall be made to the system owner or the owner's designated representative when the system has been returned to service." This section makes it clear that thesystem owneris the responsible party to be notified upon restoration in these shorter impairments.
Correct answer: D. System owner

Ground-fault monitoring circuits are required on many fire alarm systems to detect when a wire has unintentionally contacted a grounded surface. During testing, the inspectorintentionally introduces a ground to verify that the panel can detect it.
NFPA 72 (2022), Section 10.17.1:
"Ground-fault conditions shall be annunciated in accordance with the requirements of this Code." Testing method:
Thestandard functional testis tointentionally ground a circuit(typically using a known resistor) and verify the control panel indicates aground-fault supervisory signal.
Correct answer: D. Verify the ground-fault indication when circuits are grounded

NFPA 72 mandates that fire alarm system documentation be stored in a dedicated cabinet, and that cabinet must be clearly labeled. Theexact phraserequired is:
NFPA 72 (2022), Section 7.7.2:
"The cabinet shall be prominently labeled 'SYSTEM RECORD DOCUMENTS.'"
This ensures that anyone - including inspectors, AHJs, or technicians - can easily identify where critical system information is stored.
Correct answer: D. System record documents

Elevator alternate level recall is a life safety feature designed to prevent passengers from arriving at a smoke- compromised floor. NFPA 72 and elevator codes dictate that this function must activatewhen smoke is detected at the primary recall level (designated lobby).
NFPA 72 (2022), Section 21.3.3.1:
"When the elevator lobby smoke detector required for the designated recall level is activated, the elevator shall be recalled to an alternate level." This action prevents elevators from opening at a smoke-filled lobby.
Correct answer: A. In response to activation of a smoke detector located at the designated elevator lobby
