How frequently does the NEC recommend inspecting fire alarms and associated wiring?

The National Electrical Code (NEC) emphasizes the importance of maintaining fire alarm systems to ensure they function properly in the event of an emergency. Inspections should be conducted regularly, not only to comply with the NEC but also to adhere to the manufacturer's guidelines and local jurisdiction requirements.

These guidelines typically outline a schedule that may include monthly tests, semi-annual inspections, and annual maintenance, depending on the specific system and its usage. Local codes often reflect the manufacturer's recommendations and may require additional inspections based on the type of occupancy or risk factors in the environment.

Periodic inspections allow for the identification of potential issues, such as degraded wiring, obstructions, or faulty components, ensuring that the fire alarm system remains reliable and effective. Compliance with these inspection protocols is critical for the safety of building occupants and the protection of property.
