The concealable sprinkler head includes a frame having a body mounted to a source of fire suppression liquid, a pair of frame arms and a pair of corresponding drop pins slidably engaging each frame arm. The thermal trigger is supported within the sprinkler frame. The fluid deflector is secured to a drop pin and includes a generally horizontal surface. The drop pins extend substantially vertically from the horizontal plane. The inclined surface of the fluid deflector extends angled upwardly from the horizontal plane. Concealing cups surround the frame arms. A cover plate is attached to the concealment cup and covers its distal end, and a drop pin and a deflector are positioned within the concealment cup. The cover plate is removable from the concealing cup such that the drop pin and deflector axially slides out of the concealing cup into an operative position.
