FM Approval Requirements
Series EC-11 and EC-14 Extended
Coverage Upright and Pendent Sprin-
klers are to be installed in accor-
dance with the applicable FM Loss
Prevention Data Sheet for limited use
in buildings of specific roof construc-
tion and for the protection of certain
specific ordinary hazard (non-storage
and/or non-flammable or combustible
liquid) occupancies. Information pro-
vided in the FM Loss Prevention Data
Sheets relates to, but is not limited to,
hydraulic design, ceiling slope, and
obstructions, minimum and maximum
allowable spacing, and deflector-to-
ceiling distance.
These criteria may differ from UL
and/or NFPA criteria. Therefore, the
designer should review and become
familiar with FM requirements before
proceeding with design.
Installation
TYCO Series EC-11 and EC-14
Extended Coverage Upright and
Pendent Sprinklers must be installed
in accordance with this section.
General Instructions
Do not install any bulb-type sprinkler
if the bulb is cracked or there is a loss
of liquid from the bulb. With the sprin-
kler held horizontally, a small air bubble
should be present. The diameter of the
air bubble is approximately 1/16 in.
(1,6 mm) for the 135°F (57°C) to
3/32 in. (2,4 mm) for the 286°F (141°C)
temperature ratings.
A leak-tight 3/4 in. NPT sprinkler
joint should be obtained by apply-
ing a minimum-to-maximum torque of
10 to 20 ft-lb (13,4 to 26,8 N·m). Higher
levels of torque may distort the sprin-
kler inlet with consequent leakage or
impairment of the sprinkler.
Do not attempt to compensate for
insufficient adjustment in an Escutch-
eon Plate by under or over-tightening
the Sprinkler. Re-adjust the position of
the sprinkler fitting to suit.
Step 1.
Install the sprinkler with the
deflector parallel to the mounting
surface. Install pendent sprinklers in
the pendent position; install upright
sprinklers in the upright position.
Step 2.
After installing the Style 30, 40,
or 60 mounting plate (or other applica-
ble escutcheon) over the sprinkler pipe
threads and with pipe-thread sealant
applied to the pipe threads, hand-
tighten the sprinkler into the sprinkler
fitting.
Step 3.
For upright or pendent sprin-
klers, wrench-tighten using only the
W-Type 3 (End A) Sprinkler Wrench.
For the pendent sprinkler installed
with Style 30, 40, or 60 Escutcheon,
wrench-tighten the sprinkler using only
the W-Type 22 Sprinkler Wrench.
Apply the wrench recess of the appli-
cable sprinkler wrench (Figure 5 and 6)
to the sprinkler wrench flats (Figure 1).
