Household fire alarm systems have different performance requirements from commercial systems, but still must support essential alarm functions under loss of primary power.
NFPA 72 (2022), Section 29.10.5.1.1:
"The secondary power supply shall be capable of powering the system under quiescent load for 24 hours and then capable of operating the system during alarm for a period of 4 minutes (for general fire alarm) or 10 minutes (for household fire alarm systems)." Correct answer: C. 24 hours in the normal condition followed by 10 minutes of alarm

Visible notification appliances used in fire alarm systems (like strobes) must be eitherclear or redto distinguish them from other building systems.
NFPA 72 (2022), Section 18.5.1.4:
"Visible signals used in fire alarm systems shall be clear or nominal red in color." This ensuresstandardized visual recognitionduring fire emergencies.
Correct answer: D. Clear or red

NFPA 72 outlines theretention period for recordsof inspections and testing in Section14.6.3.1. These records are important for verification during audits or when reviewing system maintenance history.
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." This means records must be keptuntil the next test happensand for1 year after that, not just a fixed calendar period.
Correct answer: D. Until the next test and 1 year

McCulloh transmitters are part of older fire alarm systems but are still maintained in some jurisdictions.
Inspection focuses ongeneral condition,correct system status, andlocation verification.
NFPA 72 (2022), Table 14.3.1 - Inspection Frequencies:
UnderMcCulloh Transmitter:
* "Inspect physical condition"
* "Verify location"
* "Confirm system normal condition"
"Distinct waterflow condition" refers to alarm testing and isnotpart of theinspectionphase.
Correct answers:
* Physical condition
* System normal condition
* Verify location

Control valve supervisory switches must be tested to verify that they send a signal when the valve position changes (e.g., valve is closed). NFPA 72 requires this to be doneannually.
NFPA 72 (2022), Table 14.4.3.2 - Testing Frequencies:
Control valve supervisory switch:
Frequency:Annually
Method:Operate valve control; verify signal annunciation.
Correct answer: D. Annually
