NFPA 72 (2022), Section 18.4.1.5:

Before performing any inspection or testing activities, it's critical tonotify all affected parties, including occupants, central stations, and local authorities (as applicable), toprevent accidental dispatch of emergency services. The reason for this is clearly stated inNFPA 72 (2022 Edition), Section 14.2.3.1, which requires notification of all stakeholders before any test.

NFPA 72:2022 – 14.2.3.1

"Prior to any testing,all persons and facilities receiving alarm, supervisory, or trouble signals, and allbuilding occupantsshall benotifiedto preventunnecessary response."

This is critical for avoiding disruptions like fire department rollouts or building evacuations that could be triggered by system activations during a test. That makes the correct answer:

D. Unnecessary response

NFPA 72 requires annual testing to ensuretrouble signalsare correctly transmitted to the off-premises monitoring location (e.g., central station).

NFPA 72 (2022), Table 14.4.3.2 – Testing Frequencies and Methods:

Under “Off-Premises Transmission Equipment,”trouble signalsare testedannually.

This ensures that the system will properly report malfunctions.

Correct answer: D. Annually
