Where must installation labels be placed within the system?

Installation labels play a crucial role in the identification and maintenance of a fire alarm system. They must be placed inside the control panel cover or in a permanent location so that they are accessible for fire alarm technicians and inspectors. This placement ensures that essential information such as the installation date, system details, and service history are clearly visible and protected from environmental factors, which might otherwise erase or damage the information.

By placing the label inside the control panel cover, it becomes part of the system's integral components, making it readily available for anyone performing routine checks or troubleshooting. This is particularly important during inspections, allowing for quick verification of system compliance with local codes and standards.

Additionally, while exterior labeling of alarm devices or other locations may provide some information, they do not contain the comprehensive details necessary for the overall system understanding that the installation label provides within the control panel.
