DESIGN CRITERIA
UL and ULC Listing Criteria
The Pulsar ESFR-1 (SIN S8000) Sprinklers are UL and
ULC Listed as “Early Suppression Fast Response Sprin-
klers” for installation per NFPA 13 or other applicable
NFPA standards up to a maximum ceiling height of 40 ft.
(12,2 m).
FM Approval Criteria
The Pulsar ESFR-1 (SIN S8000) Sprinklers are FM Ap-
proved as “Early Suppression Fast Response Sprinklers”
for installation per the applicable FM Loss Prevention
Data Sheets up to a maximum ceiling height of 45 ft.

INSTALLATION
The Pulsar ESFR-1 Pendent Sprinklers must only be in-
stalled in the pendent position. With pipe thread sealant
applied to the pipe threads, use only the W-Type 2
Sprinkler Wrench (Figure 2) for installation of the Pulsar
ESFR-1 by applying the wrench to the sprinkler wrench
flats only.
NOTE
A leak tight 3/4 inch NPT sprinkler joint should be ob-
tained with a torque of 10 to 20 ft.lbs. (13,4 to 26,8 Nm).
A maximum of 30 ft.lbs. (40,7 Nm) of torque is to be used
to install sprinklers. Higher levels of torque may distort
the sprinkler inlet with consequent leakage or impairment
of the sprinkler.
CARE AND MAINTENANCE
The Pulsar ESFR-1 must be maintained and serviced in
accordance with the following instructions:
NOTE
Before closing a fire protection system main control valve
for maintenance work on the fire protection system which
it controls, permission to shut down the affected fire pro-
tection systems must be obtained from the proper authori-
ties and all personnel who may be affected by this action
must be notified.
Sprinklers which are found to be leaking or exhibiting vis-
ible signs of corrosion must be replaced.
Automatic sprinklers must never be shipped or stored
where their temperature will exceed 100°F/38°C and they
must never be painted, plated, coated, or otherwise al-
tered after leaving the factory. Modified or over-heated
sprinklers must be replaced.
Care must be exercised to avoid damage - before, dur-
ing, and after installation. Sprinklers damaged by drop-
ping, striking, wrench twist/slippage, or the like, must be
replaced.
The owner is responsible for the inspection, testing, and
maintainance of their fire protection system and devices
in compliance with this document, as well as with the ap-
plicable standards of the National Fire Protection Associa-
tion (e.g., NFPA 25), in addition to the standards of any
other authorities having jurisdiction. The installing contrac-
tor or sprinkler manufacturer should be contacted relative
to any questions.
It is recommended that automatic sprinkler systems be in-
spected, tested, and maintained by a qualified Inspection
Service.
