Operation
When TYCO Series DS-2 Dry-Type
Sprinklers, 11.2K Pendent, Standard (
5 mm bulb) and Quick Response (3 mm
bulb), and Standard Coverage are in
service, water is prevented from enter-
ing the assembly by the Plug with Gas-
keted 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 with
Gasketed Spring Plate Seal from the
Inlet, allowing the sprinkler to activate
and flow water.
