Which statement is true about surfaces in damp locations?

Surfaces in damp locations should be non-absorbent to prevent the absorption of moisture, which can lead to various issues such as mold growth, material deterioration, and effective sanitation challenges. Non-absorbent materials resist moisture, ensuring that surfaces remain stable and safe over time, thus maintaining the integrity of the fire alarm system as well as complying with safety standards.

Selecting the right materials for damp environments is crucial, as absorbent materials may harbor bacteria, cause structural problems, and compromise fire detection systems. By adhering to the guideline of using non-absorbent surfaces, installations are more durable and better suited to handle the specific challenges posed by damp conditions.
