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 residential 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.
Technical Data:
• Thermal Sensor: Nominal 3mm glass-bulb
• Sprinkler Frame : Brass
• Sprinklers’ Pressure Rating : 175 psi
Factory Hydrostatically Tested to 500 psi
• Thread Size: ½” NPT (R½)
• K-Factor: 3.0 (Actual) - F1 Res 30 LL Pendent Sprinkler
4.9 (Actual) - F1 Res 49 LL Pendent Sprinkler
5.8 (Actual) - F1 Res 58 LL Pendent & HSW Sprinkler
4.4 (Actual) - F1 Res 44 LL HSW Sprinkler

Application
Model F1 Res LL sprinklers are cULus Listed in accordance with UL 1626 for installation in accordance with
NFPA 13, NFPA 13R, and NFPA 13D. Sprinkler systems
using Model F1 Res LL sprinklers must be hydraulically
designed to provide at least the flow identified in the Technical Data tables in this bulletin. For NFPA 13 installations,
the flow per sprinkler must be the greater of: (1) the flow
listed in the applicable Technical Data table and (2) the
flow required to achieve a minimum design density of 0.1
gpm/sq ft over the design area of the sprinkler. For coverage area dimensions less than those listed in the Technical
Data tables, use the minimum required flow for the next
larger max. coverage area listed.

Installation
Models F1 Res LL sprinklers are to be installed as shown.
Model F1, F2 and FP Escutcheons, illustrated herewith, are
the only recessed escutcheons to be used with Model F1
Res LL sprinklers. Use of any other recessed escutcheon
will void all approvals and warranties. For installing Model
F1 Res LL Pendent sprinklers use only the Model W2 sprinkler Wrench; for installing Models F1 Res LL Recessed
• Model F1 Res 30 LL Recessed Pendent / F2
• Model F1 Res 49 LL & 58 LL Recessed Pendent / F1
Fig. 1
Pendent, CCP & SWC sprinklers use only the Model GFR2
sprinkler wrench; for installing Model F1 LL Res Recessed
HSW sprinklers use only the Model GFR2 Sprinkler Wrench.
Use of wrenches other than those specified may damage
these sprinklers. Install F1 Res 44 LL with a ceiling to deflector distance of 4” - 12”. Flow arrow on deflector must
point away from near wall and “Top” marking must face
ceiling.
