TYCO FIRE AND BUILDING PRODUCTS

The Model TY-QRF, 5.6 K-factor, Flush Pendent Sprinklers are quick response-standard coverage decorative fusible solder type sprinklers.

Operation
The sprinkler assembly contains a small fusible solder element. When exposed to sufficient heat from a fire, the solder melts and enables the internal components of the sprinkler to fall away. At this point the sprinkler activates with the deflector dropping into its operated position.
