Quick Response, Extended Coverage
General
Description
The Tyco Series RFII, 5.6 K-factor,
®
Extended Coverage, Light Hazard
(ECLH) "Royal Flush" Concealed Pen-
dent Sprinklers are decorative, 3 mm
bulb-type sprinklers featuring a flat
cover plate designed to conceal the
sprinkler. These sprinklers are opti-
mal for architecturally sensitive areas
such as hotel lobbies, office buildings,
churches, and restaurants.
The Series RFII sprinklers are intended
for use in automatic sprinkler systems
designed in accordance with standard
Installation rules (for example, NFPA
13). The fast-response thermal sensi-
tivity rating of the Series RFII (TY3532)
provides for a quick response, extend-
ed coverage (QREC) rating up to a
20 ft. x 20 ft. coverage area.
Each sprinkler includes a Cover Plate/
Retainer Assembly and a Sprinkler/
Support Cup Assembly. The separable,
two-piece assembly design provides
the following benefits:
• Allows installation of the sprinklers
and pressure testing of the fire pro-
tection system prior to installation
of a suspended ceiling or applica-
tion of the finish coating to a fixed
ceiling.
• Permits the removal of suspended
ceiling panels for access to building
service equipment without having

WARNING" that provides cautions
with respect to handling and instal-

a sprinkler system or its components
and cause the sprinkler to fail to
operate in a fire situation or cause it
to operate prematurely.

system and remove sprinklers.
• Provides for 1/2 inch (12,7 mm) of
vertical adjustment to allow a mea-
sure of flexibility in determining the
length of fixed piping to cut for the
sprinkler drops.
The Series RFII Sprinklers are shipped
with a Disposable Protective Cap. The
Protective Cap is temporarily removed
during installation and replaced to help
protect the sprinkler during ceiling in-
stallation or finish. The tip of the Pro-
tective Cap can be used to mark the
center of the ceiling hole into plaster
board or ceiling tiles by gently push-
ing the ceiling product against the Pro-
tective Cap. When ceiling installation
is complete, the Protective Cap is re-
moved and the Cover Plate/Retainer
Assembly is installed.
