In a garage or unfinished basement, how must a red receptacle supplying a fire alarm system be identified?

The identification of a red receptacle supplying a fire alarm system is crucial for ensuring that emergency personnel and maintenance staff can recognize its purpose immediately. The requirement for an identification plate or engraved cover with letters that are at least 1/4 inch high serves to enhance visibility and clarity, ensuring that anyone in a high-stress situation—such as during an emergency—can quickly identify the receptacle. This standard promotes safety and facilitates rapid access to the fire alarm system, which is essential in emergencies.

Using an engraved cover or a plate helps to ensure durability, making the information resistant to wear and tear in environments such as garages or unfinished basements where conditions may fluctuate. Bright colors or labels of certain sizes might assist with identification, but not as effectively as clearly marked, permanent engravings that meet the specified height requirement.
