How must fire alarm circuits be identified?

Fire alarm circuits must be clearly identified to ensure safety and proper operation, especially during emergencies or maintenance. Labeling these circuits as "fire alarm circuit" is essential as it provides unambiguous identification, allowing personnel to quickly recognize their importance and function within the overall fire detection and alarm system. This labeling helps avoid confusion with other electrical circuits, which could potentially lead to critical mistakes in emergency situations.

While color coding can aid identification, it may not convey the specific function of the circuit as effectively as a clear label. Verbally describing the circuits lacks the permanence and clarity required for quick recognition, especially in high-stress scenarios. Additionally, there are established codes and regulations that mandate proper identification of fire alarm circuits for safety compliance, making it necessary for these circuits to be distinctly labeled rather than left unmarked or undefined.
