Which of the following statements regarding fire alarm systems is accurate?

The correct answer highlights the importance of fire safety and code compliance in building systems. When fire signal cables are no longer in use or deemed abandoned, they must be removed from the premises. This requirement is in place to prevent potential hazards, such as confusion during emergencies or future maintenance activities where these cables could be mistakenly assumed to be functional. Leaving abandoned cables accessible could pose a risk not only in terms of safety but also in violating fire codes that mandate proper management of all electrical systems, particularly those related to fire prevention.

In this context, the other options do not align with safety regulations. The notion that abandoned fire alarm cables can remain accessible undermines safety principles and would be contrary to the practice of ensuring a clear and functional environment for emergency response. The idea that fire alarm circuit conductors can be attached to conduits lacks specific operational standards that govern how fire alarm systems should be installed. Lastly, while power limited circuits have specific guidelines, claiming they can be attached to any equipment ignores the limitations and requirements set forth in the National Electrical Code (NEC) and other pertinent standards meant to maintain system integrity and safety.
