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

NFPA 72 assigns theresponsibility for maintaining inspection and testing recordsto the owner or their designated representative. This ensures records are available when needed by the AHJ or for future inspections.
NFPA 72 (2022), Section 14.6.1:
"The property or building owner or the owner's designated representative shall be responsible for the inspection, testing, and maintenance of the system and for maintaining the records." This responsibility cannot be offloaded to the contractor or fire marshal unless formally designated by the owner.
Correct answer: D. Owner

After an initiating device (like a smoke detector or pull station) is triggered, NFPA 72 limits how long the control unit can delay its responseto initiating notification appliances and/or signal transmission.
NFPA 72 (2022), Section 10.11.1.1:
"Fire alarm and emergency alarm initiating devices shall be arranged to initiate the intended alarm or response within 10 seconds unless otherwise permitted. The total delay shall not exceed 30 seconds." Correct answer: C. 30 seconds

During avisual battery inspection, the technician checks forcorrosion, leakage, swelling, andloose or corroded terminals- not electrical readings (those are part of functional testing).
NFPA 72 (2022), Table 14.3.1 - Inspection Frequencies:
"Batteries (lead-acid and nickel-cadmium)" # Visual inspection items include:
* Cleanliness
* Terminal tightness
* Corrosion or leakage
* Physical damage
Voltage and charging checks are part oftesting, not visual inspection.
Correct answers:
* Check for corrosion or leakage
* Check tightness of connections

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
