Operation
When TYCO Series DS-1 Dry-Type
Sprinklers are in service, water is pre-
vented from entering the assembly by
the plug and gasketed spring plate
seal (see Figure 1) in the inlet of the
sprinkler.
The glass bulb contains a fluid that
expands when exposed to heat. When
the rated temperature is reached, the
fluid expands sufficiently to shatter
the glass bulb, and the bulb seat is
released.
The compressed spring is then able to
expand and push the water tube as well
as the guide tube outward. This action
simultaneously pulls inward on the
yoke, withdrawing the plug and gas-

keted spring plate seal from the inlet
allowing the sprinkler to activate and
flow water.
