What are drop out ceilings?

Approved drop-out ceiling panels can be installed beneath fire sprinklers. When exposed to heat from a developing fire, drop-out ceiling panels soften, distort, and fall from the ceiling grid. Heat from the growing fire activates the sprinkler which, unimpeded by the panels, controls or extinguishes the fire.
