Design
Criteria
The following general guidelines pro-
vided for the TYCO
Model ESFR-17
Pendent Sprinklers can be used for a
quick reference.
The National Fire Protection Associa-
tion (NFPA) or FM Global provide instal-
lation standards that must be used to
properly design an automatic sprinkler
system utilizing Early Suppression, Fast
Response (ESFR) Sprinklers. Conse-
quently, the appropriate standard must
be used for a given installation.
In all cases, the appropriate NFPA or
FM Global installation standard must
be referenced to ensure applicabil-
ity and to obtain complete installa-
tion guidelines. The following general
guidelines are not intended to provide
complete installation criteria.
System Type
Wet Pipe
Roof Construction
Unobstructed or obstructed construc-
tion, such as smooth ceiling, bar joists,
beam and girder.
Where the depths of the solid structural
members, such as beams and stem,
exceed 12 in. (302 mm), install ESFR
Sprinklers in each channel formed by
the structural members.
Ceiling Slope
Maximum 2 in. rise for 12 in. run (16.7%)
Maximum Coverage Area
100 ft² (9,3 m²)
In some cases, the installation stan-
dards permit a greater coverage area.
Minimum Coverage Area
64 ft² (5,8 m²) per NFPA 13 and
FM Global 2-0
Maximum Spacing
12 ft (3,7 m) for building heights up to
30 ft (9,1 m)
10 ft (3,1 m) for building heights greater
than 30 ft (9,1 m)
Minimum Spacing
8 ft (2,4 m)
Minimum Clearance to Commodity
36 in. (914 mm)
NFPA 13
Deflector-to-Ceiling Distance
6 to 14 in. (152 to 356 mm)
Centerline of Thermal Sensing
Element to Ceiling Distance
Refer to FM Global 2-0 for Storage
Sprinklers
Operation
The glass bulb contains a fluid which
expands when exposed to heat. When
the rated temperature is reached, the
fluid expands sufficiently to shatter the
glass bulb, allowing the sprinkler to
activate and water to flow.
