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 (Ref. Figure 1).
The TY720 sprinkler is designed as an
integral component of the Electronic
Sprinkler System for Storage Applica-
tions, a performance-based system
addressing high-challenging high pile
storage fire hazards. For more informa-
tion about the sprinkler system and the
system components, refer to technical
data sheet TFP360.
In place of a traditional heat-sensitive
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. A Simplex
Sprinkler Control Heat Sensor paired
with the TY720 sprinkler is connected
directly to the actuator and is in con-
tinuous communication with a Simplex
4100ES Suppression Release Panel.
The panel software algorithm analyzes
information from heat sensors in mul-
tiple locations and selects the optimal
response in a fire event. A voltage is
then sent from an algorithm-selected
heat sensor to its companion TY720
sprinkler, operating 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
Avoid damage to the actuator and
tensile link during installation. Grasp
the sprinkler only by the protec-
tor and frame wrench flats when
hand-tightening.
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 (Ref.
Figure 2).
Sprinkler Installation
Install the Model TY720 Pendent Sprin-
kler only in the pendent position in
accordance with the following:
Step 1. Apply pipe-thread sealant to
sprinkler threads.
Step 2. Hand-tighten sprinkler into
sprinkler fitting. Do not apply force to
the actuator and tensile link, handle
only by the protector and frame wrench
flats.
Step 3. Apply W-Type 21 Sprinkler
Wrench to sprinkler by fully seating
wrench recess on sprinkler wrench flats
(Ref. Figure 1).
Step 4. Wrench-tighten sprinkler to
obtain 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).

Ordering
Procedure
Contact your local distributor for avail-
ability. When placing an order, indicate
the full product name and Part Number
(P/N).
Sprinkler Assemblies
Specify: Model TY720, K=16.8, Elec-
tronic Control, Pendent Sprinkler,
natural brass, P/N 58-461-1-000
Sprinkler Wrench
Specify: W-Type 21 Sprinkler Wrench,
P/N 56-001-0-686
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.
(Ref. Installation Section.)
The owner is responsible for the
inspection, testing, and mainte-
nance of their fire protection system
and devices in compliance with
this document, as well as with the
applicable standards of the National
Fire Protection Association (e.g., NFPA
25), in addition to the standards of any
authorities having jurisdiction. Contact
the installing contractor or product
manufacturer with any questions.
It is recommended that automatic
sprinkler systems be inspected, tested,
and maintained by a qualified Inspec-
tion Service in accordance with local
requirements and/or national codes.
Suppression Release Panel
For information about the inspection,
test and maintenance (ITM) of the
Simplex 4100ES Suppression Release
Panel, see the System Test Proce-
NOTICE
Higher levels of torque may distort
sprinkler inlet with consequent leakage
or impairment of sprinkler.
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 10th 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.
