What information should be displayed on inspection labels?

The correct option emphasizes the importance of comprehensive documentation on inspection labels. Inspection labels serve as official records of fire alarm system inspections, ensuring transparency and accountability in fire safety compliance.

Displaying the date of inspection, the signature of the licensed technician who performed the inspection, and their license number provides clear identification and verification of the professional responsible for the inspection. This information helps ensure that the inspection was conducted by a qualified individual and within a specified timeframe, which is critical for maintaining the integrity and functionality of fire alarm systems.

The other options do not provide a complete or appropriate set of information required. Simply listing inspection results lacks the context of who conducted the inspection or when, which could lead to confusion regarding accountability. Only mentioning the type of inspection performed leaves out crucial details about the professional qualifications involved. Lastly, a stamped signature does not fulfill the requirement for a personal signature, as it cannot confirm the identity of the technician and their credentials, which are necessary for legitimizing the inspection process.
