An acceptance test for a fire alarm system in a new apartment building should be...

IFC Section 901.5 (Acceptance Tests) requires fire protection systems, including fire alarms, to be tested upon completion to ensure compliance with NFPA 72 (National Fire Alarm and Signaling Code) and the IFC. The contractor’s verification of full compliance (B) signals readiness for the official acceptance test by the fire code official, ensuring all components are installed and functional. Option A (zone-by-zone testing) is impractical for final acceptance. Option C ties the test to water supply, irrelevant to alarms. Option D (one year) is excessive and not required by IFC or NFPA 72 for initial acceptance. Thus, B is correct.
