Operation

When TYCO Series DS-3 Dry-Type
Sprinklers, 11�2K Horizontal Sidewall,
Standard Response, Extended Cov-
erage, Ordinary Hazard (ECOH) are in
service, water is prevented from enter-
ing the assembly by the Plug with
Sealing Assembly (Ref� 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
Sealing Assembly from the Inlet allow-
ing the sprinkler to activate and flow
water�
