Upright and Pendent Intermediate Level Sprinklers
Quick Response
General
Description
The Series TY-FRL, 5.6 and 8.0 K-fac-
tor Upright and Pendent Intermediate
Level Sprinklers described in this data
sheet are automatic sprinklers of the
"quick response" solder type. They are
"standard spray" sprinklers intended
for use in fire sprinkler systems de-
signed in accordance with the stand-
ard installation rules recognized by the
applicable Listing or Approval agency
(e.g., UL Listing is based on NFPA
requirements). Both the Pendent and
Upright Sprinklers produce a hemi-
spherical water distribution pattern be-
low the deflector.
Intermediate Level Sprinklers are pri-
marily designed for use in rack storage
sprinkler systems where their ther-
mally sensitive elements must be
shielded from the water spray of higher
elevation sprinklers that could operate
earlier during a fire. Intermediate Level
Sprinklers are also used in other appli-
cations such as beneath open gridded
catwalks.
