UNIVERSAL MODEL A/Q-71
QUICK RESPONSE, 3 mm BULB TYPE, 5.6 K-FACTOR, 1/2" NPT**
GENERAL DESCRIPTION
The 5.6 K-Factor Quick Response Uni-
versal Model A/Q-71 Horizontal Side-
wall and Recessed Horizontal Side-
wall Sprinklers (Ref. Figure A) are
automatic sprinklers of the "quick re-
sponse" frangible bulb type. They are
"standard spray sprinklers" intended
for use in fire sprinkler systems de-
signed in accordance with the stand-
ard installation rules recognized by the
applicable Listing or Approval agency
(e.g., UL Listing is based on NFPA 13
requirements).
Horizontal sidewall sprinklers are gen-
erally used in lieu of pendent and up-
right sprinklers because of building
construction or installation economy
considerations. They are designed for
installation along a wall or side of a
beam and just beneath a smooth ceil-
ing. Installed with their centerline of
waterway horizontal, these sprinklers
produce a quarter-spherical water dis-
charge pattern that is predominately
directed downward and outward from
the deflector; however, a portion of the
spray is also directed towards the back
wall.
The Model A/Q-71 Sprinklers feature a
unique "Deflector Hat" which provides
a low profile for improved aesthetics.
The recessed versions of the Model
A/Q-71 Sprinkler are obtained by util-
izing the Model A/Q-71 Sprinkler in
combination with either the Model
F700 or F705 Recessed Escutcheon
(Ref. Figures A and B). The F700 and
F705 Recessed Escutcheons have a
separable two-piece design which al-
lows installation of the sprinklers and
pressure testing of the fire protection
system, prior to wall construction
and/or application of a finish coat to
the wall. They also permit refinishing
of a wall surface without having to first
shut down the fire protection system
and remove the sprinklers.
The vertical adjustment provided by
the F700 or F705 substantially re-
duces the accuracy to which the length
of fixed pipe nipples to the sprinklers
must be cut. Also, the Closure has a
1/2 inch (12,7 mm) wide flange which
provides ample clearance for covering
the mounting hole.
