Operation: A fusible alloy pellet is
compressed with a bearing disc into
a copper housing by a ball plunger.
Heat is absorbed by the heat
collecting fins and conducted to the
alloy pellet. At the rated temperature
the alloy melts, causing the ball
plunger to drop, freeing balls from
the retaining groove. This movement
allows system water pressure to
force the orifice sealing mechanism
and deflector assembly open. Water
is then discharged in a designed flow
pattern.
