The branch circuit supplying fire alarm equipment shall be permitted to supply which loads?

The branch circuit supplying fire alarm equipment shall be permitted to supply which loads?

• A. Not more than 3 additional outlets
• B. Not more than 5 additional outlets
• C. No other loads
• D. Not more than one additional outlet

Answer: (C)

The main idea is that fire alarm power must be dedicated. The branch circuit that powers fire alarm equipment is kept separate from general lighting and receptacle circuits so the system has clean, reliable power that isn’t affected by other loads. If the same circuit fed outlets or other non-alarm devices, voltage drops or overcurrents could occur, potentially causing alarms to fail to operate when needed or tripping the circuit during an event. Because of that need for dependable operation and easy supervision, this branch circuit is permitted to supply no other loads—only the fire alarm equipment and its associated devices.
