Operation

When TYCO Series DS-2 Dry-Type

Sprinklers, 11.2K Pendent, Extended

Coverage, Light and Ordinary Hazard

are in service, water is prevented from

entering the assembly by the Plug

with 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 with

Gasketed Spring Plate Seal from the

Inlet allowing the sprinkler to activate

and flow water.
