Why is plenum rated often a requirement for ceiling mounted access points?

Plenum-rated access points are often required for ceiling-mounted installations due to fire safety regulations. The plenum space, which is used for air circulation in heating and cooling systems, can facilitate the spread of fire and smoke. Using plenum-rated equipment ensures that the materials can withstand higher temperatures and are made from non-toxic materials, reducing the risk of harmful fumes in case of a fire. This compliance helps ensure the safety of the building occupants and meets building code requirements.
