Product Description
Reliable Models F1FR LO and F1FR LO Recessed Sprinklers
are quick response sprinklers which combine the durability of a
standard sprinkler with the attractive low profile of a decorative
sprinkler.
The Models F1FR LO and F1FR LO Recessed automatic
sprinklers utilize a 3.0 mm frangible glass bulb. These sprinklers
have demonstrated response times in laboratory tests which
are five to ten times faster than standard response sprinklers.
This quick response enables the Model F1FR LO and F1FR LO
Recessed sprinklers to apply water to a fire much faster than
standard sprinklers of the same temperature rating.
The glass bulb consists of an accurately controlled amount of
special fluid hermetically sealed inside a precisely manufactured
glass capsule. This glass bulb is specially constructed to provide
fast thermal response. The balance of parts are made of brass,
copper and beryllium nickel.
At normal temperatures, the glass bulb contains the fluid in
both the liquid and vapor phases. The vapor phase can be seen
as a small bubble. As heat is applied, the liquid expands, forcing
the bubble smaller and smaller as the liquid pressure increases.
Continued heating forces the liquid to push out against the bulb,
causing the glass to shatter, opening the waterway and allowing
the deflector to distribute the discharging water.
The temperature rating of the sprinkler is identified by the
color of the glass bulb.
Application
Quick response sprinklers are used in fixed fire protection
systems: Wet, Dry, Deluge or Preaction. Care must be
exercised that the orifice size, temperature rating, deflector
style and sprinkler type are in accordance with the latest
published standards of the National Fire Protection Association
or the approving Authority Having Jurisdiction. Quick response
sprinklers are intended for installation as specified in NFPA 13,
FM Global Loss Prevention Data Sheet 2-8N or other applicable
standards. Quick response sprinklers and standard response
sprinklers should not be intermixed.

Installation
Quick response sprinklers are intended for installation as
specified in NFPA 13, FM Global Loss Prevention Data Sheet
2-8N or other applicable standards. Quick response sprinklers
and standard response sprinklers should not be intermixed.
The Model F1FR LO Recessed Quick Response Sprinklers
are to be installed as shown. The Model F1 or F2 Escutcheons
illustrated are the only recessed escutcheons to be used with
the Model F1FR LO Sprinklers. The use of any other recessed
escutcheon will void all approvals and negate all warranties.
When installing Model F1FR LO Sprinklers, use the Model D
Sprinkler Wrench. When installing Model F1FR LO Recessed
Pendent or Sidewall Sprinklers, use the Model GFR1 Sprinkler
Wrench. Any other type of wrench may damage these sprinklers.
Glass bulb sprinklers have orange bulb protectors to minimize
bulb damage during shipping, handling and installation.
REMOVE THIS PROTECTION AT THE TIME THE SPRINKLER
SYSTEM IS PLACED IN SERVICE FOR FIRE PROTECTION.
Removal of the protectors before this time may leave the bulb
vulnerable to damage. RASCO wrenches are designed to install
sprinklers when covers are in place. REMOVE PROTECTORS
BY UNDOING THE CLASP BY HAND. DO NOT USE TOOLS
TO REMOVE THE PROTECTORS.

Maintenance
TheModelsF1FRLOandF1FRLORecessedSprinklersshould
be inspected quarterly and the sprinkler system maintained in
accordance with NFPA 25. Do not clean sprinklers with soap
and water, ammonia or any other cleaning fluids. Remove
dust by using a soft brush or gentle vacuuming. Remove any
sprinkler which has been painted (other than factory applied)
or damaged in any way. A stock of spare sprinklers should be
maintained to allow quick replacement of damaged or operated
sprinklers. Prior to installation, sprinklers should be maintained
in the original cartons and packaging until used to minimize the
potential for damage to sprinklers that would cause improper
operation or non-operation.
