IMPORTANT
Refer to Technical Data Sheet
TFP2300 for warnings pertaining to
regulatory and health information.
Always refer to Technical Data
Sheet TFP700 for the “INSTALLER
WARNING” that provides cautions
with respect to handling and instal-
lation of sprinkler systems and com-
ponents. Improper handling and
installation can permanently damage
a sprinkler system or its compo-
nents and cause the sprinkler to fail
to operate in a fire situation or cause
it to operate prematurely.

General
Description
The TYCO Model TY720 Pendent
Sprinkler is an electronically controlled
sprinkler having a nominal K-factor of
16.8, see Figure 1.
The TY720 sprinkler is designed as an
integral component of the EAS-1 Elec-
tronically Activated Sprinkler System
for Storage Applications, a perfor-
mance-based system addressing
highly challenging high pile storage fire
hazards. For more information about
the sprinkler system and the system
components, refer to technical data
sheet TFP360.
In place of a traditional heat-sensi-
tive glass bulb or solder element, the
TY720 sprinkler features an electronic
linear actuator and tensile link with
hook and strut arrangement holding a
button and seal against the waterway.
An AUTOPULSE Sprinkler Control Heat
Sensor paired with the TY720 sprinkler
is connected directly to the actuator
and is in continuous communication
with an AUTOPULSE EAS-1 Control
Unit.
The control unit software algorithm
analyzes information from heat sensors
in multiple locations and selects the
optimal response in a fire event. An
electrical pulse is then delivered from
an algorithm-selected heat sensor to
its companion TY720 sprinkler, oper-
ating the actuator and breaking the
tensile link, allowing waterflow from
the sprinkler.
NOTICE
The TY720 Sprinkler described herein
must be installed and maintained in
compliance with this document, as
well as with the applicable standards
of the National Fire Protection Associa-
tion, in addition to the standards of any
authorities having jurisdiction. Failure
to do so may impair the performance
of these devices.
The owner is responsible for main-
taining their fire protection system
and devices in proper operating con-
dition. Contact the installing contrac-
tor or product manufacturer with any
questions.

Installation
Install the Model TY720 Pendent Sprin-
kler in accordance with this section.
General Instructions
Take care handling the sprinkler during
installation to avoid damage to the
actuator and tensile link. Hold the
sprinkler by the frame and wrench flats,
and do not grasp the actuator, when
hand-tightening into position.
A leak-tight 3/4 in. NPT sprinkler joint
should be obtained by applying pipe-
thread sealant to the sprinkler threads
and wrench-tightening using only
the W-Type 21 Sprinkler Wrench, see
Figure 2.
Sprinkler Installation
Install the Model TY720 Pendent Sprin-
kler only in the pendent position as
follows:
Step 1. Apply pipe-thread sealant to
sprinkler threads.
Step 2. Hold the sprinkler by the frame
and wrench flats, and do not grasp or
apply force to the actuator and tensile
link. Insert and hand-tighten the sprin-
kler into the sprinkler fitting.

Care and
Maintenance
TY720 Sprinklers must be maintained
and serviced in accordance with this
section.
Submit 10 samples or 1% of the total
number of installed sprinklers, which-
ever is greater, to UL for testing 5 years
after manufacturing, then again at 10
years and followed by annual testing
after the tenth year. Sampling can be
from mock-installations not connected
to the fire protection sprinkler system
but are located in the same orienta-
tion and environment as the system
sprinklers.
Before closing a fire protection system
main control valve for maintenance
work on the fire protection system that
it controls, permission to shut down the
affected fire protection system must be
obtained from the proper authorities
and all personnel who may be affected
by this action must be notified.
Sprinklers which are found to be
leaking or exhibiting visible signs of
corrosion must be replaced.
Care must be exercised to avoid
damage to the sprinklers before,
during, and after installation. Sprin-
klers damaged by dropping, strik-
ing, wrench twist/slippage, or the like,
must be replaced. Also, replace any
sprinkler that has a damaged actuator,
tensile link or other operative parts.
(See Installation Section.)
The owner is responsible for the
inspection, testing, and mainte-
nance of their fire protection system
Step 3. Apply a W-Type 21 Sprinkler
Wrench to the sprinkler by fully seating
the wrench recess on the sprinkler
wrench flats, see Figure 1.
Step 4. Wrench-tighten the sprinkler
to obtain a leak-tight joint either 1 to
1-1/2 turns beyond hand-tightened, or
by applying a minimum-to-maximum
torque of 10 to 20 lb-ft (13,4 to 26,8
N∙m).
NOTICE
Higher levels of torque may distort
sprinkler inlet with consequent leakage
or impairment of sprinkler.
