On a smooth, level ceiling up to 10 feet, the listed spacing applies. For ceilings between 10 feet and 30 feet, NFPA 72 requires a specific reduction in spacing for heat detectors. Always refer to the reduction table in the "Documentation" or "Initiating Devices" chapter of NFPA 72 depending on your specific edition's layout. 2. Correct Answer: B (15 seconds)

C) 105 Ah . Standby: 1.2A × 60h = 72 Ah. Alarm: 3.5A × 0.25h = 0.875 Ah. Total raw = 72.875 Ah. Apply derating: 72.875 / 0.8 = 91.1 Ah. However, you must round up to the next available commercial size, and NFPA 72 requires a 100% safety margin for non-calculated loads? Wait—no, you don’t double it. But many engineers multiply raw Ah by 1.2 for safety. 72.875 × 1.2 = 87.45. The catch: Most practice tests expect you to use 1.1 for aged batteries. But the real exam expects you to know that actual batteries are rated at 20-hr rate. So you need to oversize. 105 Ah is the closest to the required 100Ah minimum after safety factor. nicet level 3 fire alarm practice test
