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

Candela ratings arevisually confirmedduringinitial acceptance. Further inspection is requiredonly if a device malfunction occursor areacceptance testis performed.

NFPA 72 (2022), Section 18.5.5.7:

“The candela rating shall be verified at initial acceptance and when there is reason to believe the device is not operating properly.”

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

Amultimeteris the standard tool used by fire alarm technicians to measure bothbattery voltageandcharging current.

NFPA 72 (2022), Table 14.4.3.2 – Testing Methods for Batteries:

Testing includes checking the voltage and current — commonly done using a multimeter.

Multimeters are capable of readingDC voltage(for battery levels) andamperage(for charge current).

NFPA 72provides the requirements forinstallation, testing, and maintenanceofcarbon monoxide detection systems. This includes required signals, testing intervals, and integration with fire alarm control units.

NFPA 72 (2022), Chapter 29 – Single- and Multiple-Station Alarms and Household Fire Alarm Systems:

Also coversCO detection and testing proceduresper Section 29.10.

NFPA 720(the former CO detection standard) was integrated into NFPA 72 in recent editions.

Correct answer: C. NFPA 72
