When should a yellow label be utilized?

The use of a yellow label is specifically intended to indicate that a fire alarm system does not meet applicable codes and standards. This serves as an important warning sign for both operators and inspectors, signaling that there are deficiencies or non-compliance issues with the system that could affect its performance and safety. Labeling the system with a yellow label helps ensure that necessary corrections or improvements are made promptly to bring the system into compliance, thus safeguarding the occupants of the building and ensuring reliability in emergency situations.

In contrast, other scenarios, such as a fully operational system, one that meets all applicable codes, or a newly installed system, would not warrant a yellow label, as these circumstances indicate compliance and readiness rather than deficiencies.
