Final answer:
NFPA 72 mandates that fire alarm equipment operate within the manufacturer's specified voltage range to maintain functionality and reliability. Adhering to this standard is essential for the safety and compliance of fire alarm systems.
Step-by-step explanation:
NFPA 72, known as the National Fire Alarm and Signaling Code, sets forth requirements to ensure that fire alarm systems are reliable and effective in alerting building occupants of emergencies. According to NFPA 72, fire alarm equipment must be capable of operating within a specific voltage range to function correctly under various conditions. Although the precise voltage range may be updated in different editions of the standard, it generally specifies that fire alarm systems should operate within the manufacturer's specified voltage range to maintain their listed performance. This is critical as it ensures that fire alarms work effectively during emergencies when they are most needed.
Maintaining the electrical requirements as per NFPA 72 is essential for the safety and compliance of a building's fire alarm system. It also contributes to the reliability of these systems, which in the event of a fire can save lives and property.
