What kind of approval is necessary when installing protective covers that emit an alarm signal?

When installing protective covers that emit an alarm signal, obtaining AHJ (Authority Having Jurisdiction) approval is crucial. The AHJ is typically responsible for enforcing local laws and regulations related to fire safety and building codes. Their approval ensures that the installation meets all applicable safety standards and complies with local fire codes. This step is essential because the AHJ can assess the potential impact on the overall fire protection system and make sure that the installation does not interfere with other safety measures.

While other approvals, such as from insurance or compliance with the Electrical Code, may be relevant to different aspects of a fire alarm system, the AHJ’s evaluation is specifically focused on safety and adherence to the standards that govern fire alarm systems and their components within the community. It's the AHJ's responsibility to confirm that installations provide adequate safety and performance, ensuring that alarm signals function as intended in case of an emergency.
