Operation

The sprinkler assembly contains a
small fusible solder element. When
exposed to sufficient heat from a fire,
the solder melts and enables the inter-
nal components of the sprinkler to fall
away. At this point the sprinkler acti-
vates with the deflector dropping into
its operated position (Figure 1C), per-
mitting water to flow.
