Residential, Pendent and Recessed Pendent Sprinkler
Model FR-RES K-Factor: 4.9 SIN: SS4451
GENERAL DESCRIPTION
The Model FR-RES Residential Pendent and Recessed Pendent Sprinklers are fusible link type automatic sprinklers. They are
durable and fast responding. The Model FR-RES is designed for residential occupancies and is perfect for use in homes, hotels
and other living quarters.
The Model FR-RES is to be used in wet pipe residential sprinkler systems for One- and Two- Family Dwellings and
Manufactured Homes per NFPA 13D; wet pipe residential sprinkler systems for Residential Occupancies up to and Including
Four Stories in Height per NFPA 13R; or, wet pipe sprinkler systems for the residential portions of any occupancies per NFPA
13.
The Model FR-RES has a 4.9 (70.6 LPM/bar
1/2
) K-factor that meets the required residential flow rates with minimal residual
pressure, which allows for smaller pipe sizes and water supply requirements.
For extended installation flexibility, the Model FR-RES provides 1/2 inch (12.7mm) vertical adjustment with the D1 or D3
Recessed Escutcheon.
NOTICE

escape or evacuate in case of a fire. However, residential fire sprinkler systems are not a substitute for fire safety
awareness or fire safety construction required by building codes.
