Product Description
Model F1 Res LL Pendent sprinklers (Figs. 1, 2, 3, & 4) are
fast response sprinklers combining excellent durability, high
sensitivity glass-bulb and low profile decorative design. The
F1 Res LL Horizontal Sidewall sprinklers (Figs. 5, & 6) are
equally attractive when above ceiling piping cannot be used.
The 3mm glass-bulb pendent sprinklers permit the efficient
use of residential water supplies for sprinkler coverage in resi-
dential fire protection design.
The low flow F1 Res LL sprinklers are specially engineered
for fast thermal response to meet the sensitive fire protection
application needs of the latest residential market standards
(UL 1626 Standard). Upon fire conditions, rising heat causes
a sprinkler’s heat-sensitive glass-bulb to shatter, releasing the
waterway for water flow onto the deflector, evenly distributing
the discharged water to control a fire.

• Thermal Sensor: Nominal 3mm glass-bulb
• Sprinkler Frame : Brass
• Sprinklers’ Pressure Rating : 175 psi
