DESIGN CRITERIA
The Model F895 ECOH Sprinklers
must only be installed in accordance
with the applicable UL and C-UL List-
ing or FM Approval requirements, as
indicated below. Only the F700 Re-
cessed Escutcheon is to be used for
recessed installation:
UL and C-UL Listing Requirements
1. The F895 Sprinklers may be used
for the coverage areas shown in Ta-
ble B, based on maintaining the mini-
mum specified flow rate as a func-
tion of coverage area and hazard
group for all of the sprinklers in the
design area.
2. With respect to heat sensitivity, the
F895 ECOH Sprinklers are permit-
ted to be used with unobstructed or
non-combustible obstructed ceiling
construction as defined and permit-
ted by NFPA 13. For example:
•
Unobstructed, combustible or non-
combustible, ceiling construction
with a deflector to ceiling/roof deck
distance of 1 to 12 inches (25 to 300
mm).
•
Obstructed, noncombustible, ceil-
ing construction with a deflector lo-
cation below structural members of
1 to 6 inches (25 to 150 mm) and a
maximum deflector to ceiling/roof
deck distance of 22 inches (550
mm).
3. The minimum allowable spacing be-
tween the F895 ECOH Sprinklers, to
prevent cold soldering, is 8 feet (2,4
m) for upright sprinklers and 9 feet
(2,7 m) for pendent sprinklers.
4. The Model F895 ECOH Sprinklers
are to be installed in accordance
with all other requirements of NFPA
13 for extended coverage upright
and pendent sprinklers.
FM Approval Requirements
The F895 ECOH Sprinklers are to be
installed in accordance with the appli-
cable Factory Mutual Loss Prevention
Data Sheet for limited use in buildings
of specific roof construction and for the
protection of certain specific ordinary
hazard (non-storage and/or non-flam-
mable or combustible liquid) occupan-
cies. Information provided in FM Loss
Prevention Data Sheets relate to, but
are not limited to, hydraulic design,
ceiling slope and obstructions, mini-
mum and maximum allowable spac-
ing, and deflector-to-ceiling distance.
