Where should a Yellow or Red label be attached?

A Yellow or Red label serves as an essential indicator for fire alarm systems, providing crucial information regarding the operation and status of the equipment. The correct placement of these labels is on the outside of the control panel or in a permanent location that is easily visible and accessible.

Attaching the label to the outside of the control panel allows for immediate awareness of the system's condition without needing to open the panel, which could be necessary during emergency situations. This visibility is key because it ensures that first responders or maintenance personnel can quickly assess the situation and understand any faults or statuses indicated by the label. The requirement for a "permanent location" also highlights the importance of ensuring that the labels are not only accessible but also consistently sighted by people who might need the information.

In contrast, placement only inside the control panel restricts visibility and accessibility during emergencies. Similarly, placing it on the ceiling of the control room may also hinder quick awareness, as it is not as easily noticed as a label on the outside of the control panel. Therefore, the correct answer emphasizes strategic placement for maximum effectiveness and safety in managing fire alarm systems.
