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
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
The heat sensitivity and water distribution design of Model FR-RES allows for an increased chance of residents to
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.
WARNINGS
The Model FR-RES must be installed and maintained in accordance with the rules stated herein as well as in
compliance with the applicable standards of the National Fire Protection Association regulations and the standards of
any other authorities having jurisdiction.
In the event of this condition, consult the authorities having jurisdiction for guidance and approval.
Failure to do so may impair the integrity of these devices.
It is the responsibility of the installing contractor to provide a copy of this document to the owner or their

  • Page 1 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.
  • Page 2 : 2 of 8 Page FIGURE 1. Model FR-RES K4.9 OPERATION The sprinkler assemblies fusible link is comprised of two link halves that are joined together with a thin layer of solder. When the rated temperature is reached, the solder melts and the two link halves separate. This leads to the water flow to be distributed on the affected fire area.
  • Page 3 DESIGN CRITERIA The herein stated rules for use and installation of Model FR-RES are provided by the manufacturer and must be strictly implemented for safe and full results. Only the D1 or D3 Recessed Escutcheon, as applicable, is to be used for recessed pendent installations.
  • Page 4 : 4 of 8 Page Hydraulic Design Criteria The minimum required sprinkler flow rates for systems designed to NFPA 13D or 13R are given in TABLE A as a function of temperature rating and the maximum allowable coverage area. The sprinkler flow rate is the minimum required discharge from the most hydraulically demanding sprinkler from each of the total number of “design sprinklers”...
  • Page 5 Use only Wrench FR-S or Socket FR-H for installation of Model FR-RES sprinklers. Use of any other wrench or socket is prohibited and may cause damage to the sprinkler.
