Which element must be included on a Red label regarding the licensing information?

The element that must be included on a Red label regarding licensing information is the licensee signature and license number. This information is critical as it provides a means of identification for the individual holding the license. It serves to authenticate the validity of the license and ensures that the person responsible for the fire alarm system has been properly trained and certified. The signature indicates that the licensee is endorsing the information on the label, establishing accountability.

In the context of fire alarm systems, having this information prominently displayed helps regulatory authorities and fellow professionals verify compliance quickly during inspections or assessments. Therefore, the inclusion of the licensee signature and license number fosters transparency and trust in the operational integrity of the fire alarm services being provided.
