Regarding feeder circuit wiring in emergency systems, which of the following is true about installations in assembly occupancies?

In the context of emergency systems within assembly occupancies, it is crucial that feeder circuit wiring remains accessible for maintenance. This is because ease of access is necessary to ensure that the systems can be properly maintained, inspected, and tested to guarantee their reliability during an emergency. Regular maintenance is vital to the performance of fire alarm and emergency systems, as it ensures that all components function as intended when needed.

Accessibility allows maintenance personnel to quickly identify any issues, perform repairs, and replace parts without excessive delay, which could be critical in emergency situations. Maintaining accessibility also aligns with code requirements and best practices that emphasize safety and functionality in environments where large numbers of people gather.

Other options, while related to safety and installation practices, are not necessarily requirements that are equally applicable across all assembly occupancies or emergency systems. Prioritizing access for maintenance helps in maintaining a high level of safety and functionality, which is why this option stands out as the correct choice.
