GENERAL DESCRIPTION
The 8.0 K-Factor (17/32 inch orifice),
Model FR-1 QR-EC/EC Horizontal
Sidewall Sprinklers (Ref. Figure A) are
automatic sprinklers of the “quick re-

sprinklers” intended for use in fire
sprinkler systems designed in accord-

rules recognized by the applicable
Listing or Approval agency (e.g., UL
Listing is based on NFPA 13 require-

to 16 ft. x 24 ft. ( 4,9 m x 7,3 m) are
generally used in lieu of pendent and
upright sprinklers because of building
construction or installation economy
considerations. They are designed for
installation along a wall or the side of
a beam and just beneath a smooth and
level ceiling.

TECHNICAL DATA
The 8.0 K-Factor Model FR-1 QR-
EC/EC Horizontal Sidewall Sprinklers
are rated for use at a maximum service
pressure of 175 psi (12,1 bar) and they
are available in the temperature rat-
ings and finishes indicated in Table A.
The flow “Q” in GPM (LPM) is deter-
mined by the following formula:
where the nominal discharge coeffi-
cient “K” equals 8.0 (115,2) and “p”
equals the residual flowing pressure in
psi (bar).
The FR-1 utilizes a dezincification re-
sistant bronze alloy frame. The strut is
silicone bronze and the deflector is
brass. The Hook is phosphor bronze,
the two halves of the Link Assembly
are nickel, the Ejection Spring is In-
conel, the Button is brass, and the
