Claim 1:
2. A concealable sprinkler head in combination with a space:
the concealable sprinkler head comprising:
a sprinkler frame comprising:
a body mountable to a fire suppression liquid source, the body defining a proximal inlet, a distal outlet and an internal fire suppression liquid passageway extending therethrough;
a pair of frame arms axially extending away from the body;
a pair of corresponding drop pins each being slidably engaged with a respective frame arm;

a thermal trigger supported within the sprinkler frame and configured to support a sealing plug in a sealing position to seal the internal fire suppression liquid passageway and maintain the sprinkler head in a non-spraying state, wherein activation of the thermal trigger releases the sealing plug from the sealing position,
a directional fluid deflector secured to the pair of drop pins, the fluid deflector including a generally horizontal surface, the pair of drop pins extending substantially orthogonally from the horizontal surface, and an inclined surface extending angularly upwardly from the horizontal surface toward the sprinkler frame;
a concealing cup having a generally horizontal upper wall attached to, and horizontally outwardly projecting from, the body of the sprinkler frame, a skirting side wall extending axially distally from the upper wall, and an open base end, the pair of frame arms being positioned within the concealing cup; and
a cover plate attached to the concealing cup, covering the open base end of the concealing cup and maintaining the sprinkler frame in a compressed, non-activated position, wherein the pair of drop pins and the deflector are positioned within the concealing cup, the cover plate being removable from the concealing cup at a predetermined temperature, permitting the pair of drop pins and the deflector to axially slide out of the concealing cup through the open base end thereof into an extended operational position; and

the space comprising a ceiling and a window within the space and oriented substantially perpendicularly to the ceiling;
the concealable sprinkler head being mounted in the ceiling such that the inclined surface of the directional fluid deflector is further away from the window than the generally horizontal surface, whereby fire suppression liquid is deflectable onto the window.
