Who can validate the operation of a central station?

The operation of a central station can be validated by the FDNY, as they are the authority responsible for overseeing fire safety and emergency communication systems within New York City. The FDNY ensures that these systems comply with city regulations and standards. Their validation process involves assessing the functionality and reliability of the central station, which is critical for effective emergency response.

Local fire marshals primarily deal with compliance and enforcement of fire codes within specific jurisdictions rather than the validation of communication systems. Building inspectors focus on the physical structure and compliance with building codes, not the operational aspects of central stations. Insurance companies may have interests in the operational reliability of communication systems for underwriting purposes, but they do not possess the authority to validate them. Thus, the FDNY stands out as the correct answer, responsible for ensuring that central stations function properly and adhere to necessary regulations.
