How often should the written certification for a complete fire alarm system be renewed?

The written certification for a complete fire alarm system should be renewed at least annually. This requirement is in place to ensure that fire alarm systems remain functional, compliant, and effective in providing safety to occupants and property. Regular certification helps to identify any potential issues or maintenance needs, ensuring that the system operates correctly in the event of an emergency.

Annual certification also aligns with many regulatory standards and best practices for fire safety, which require routine checks and updates to systems to maintain their reliability. This frequency allows facilities to stay current with any changes in technology or safety protocols that may have emerged since the last certification, thereby enhancing overall safety measures.

The other options, while they may suggest some level of upkeep, do not meet the recognized standard for comprehensive safety and compliance in most jurisdictions.
