Which of the following statements regarding branch circuits for fire alarm systems is true?

Branch circuits for fire alarm systems must be dedicated for fire alarm use to ensure the integrity and reliability of the fire alarm system. This requirement is crucial because fire alarm systems need to operate under specific conditions to guarantee timely detection and alerting in the event of a fire. By having a dedicated circuit, it prevents interference from other electrical loads, which could compromise the system's performance.

Additionally, maintaining a dedicated circuit simplifies troubleshooting, enhances safety, and is often a requirement of the National Fire Protection Association (NFPA) standards, which help ensure that fire alarm systems function appropriately in emergencies. This dedication significantly reduces the risks associated with power surges or disturbances from other systems, such as lighting or environmental controls, which may share a circuit.
