What is true about the conductors of power-supply and fire alarm circuits when placed in the same cable?

When discussing the conductors of power-supply and fire alarm circuits, it's important to consider safety and regulatory compliance. The correct choice highlights that if both the power-supply and fire alarm circuits are connected to the same piece of equipment, it's permissible for their conductors to be housed within the same cable. This is often due to shared functionalities and the need for reliable power supply to critical systems, as long as proper installations are followed in accordance with the National Electrical Code (NEC) or other relevant regulations.

Keeping the conductors together when they are part of the same system can simplify installation and maintenance, ensuring that the fire alarm system is receiving adequate power in case of an emergency, all while adhering to necessary safety practices. However, considerations must always be taken to ensure that the installation does not conflict with any specific codes or standards that might be applicable in a given jurisdiction.

In scenarios where the conductors are from different systems or equipment, placing them in the same cable could lead to issues such as electrical interference or compliance violations, underscoring the importance of proper conductor management based on their connections and functions within a system.
