Important safetY InformatIon
WARNING
Read all the product safety information prior to installation. Automatic gate operators move the gate with high force and
can cause serious injury and death! Make sure the automatic gate operator is installed to reduce the risks of entrapment.
Verify the gate operator is installed to comply with all safety standards and local and federal regulations.
Understand that you as the site designer, installer, maintenance crew, or owner/user must consider the risks asso-
ciated with gate operators. Be sure to take responsibility, read, and follow the Important Safety Information in this
manual and review all the literature that accompanies the product.
Hazards, associated with automatic gates, can be reduced with proper site design, installation, and use. Install-
ers, maintenance crews, and owners/users must read and follow the safety requirements found in the HySecurity
product manuals.
It is important that only qualied installers handle the installation of the HySecurity equipment and gate operator.
A “qualied” installer has one of the following:
• A minimum of three years experience installing similar equipment
• Proof of attending a HySecurity Technical Training seminar within the past three years
• Signicant manufacturer endorsements of technical aptitude in gate operator installation and operation
Underwriter Laboratories (UL) and the American Society for Testing and Materials (ASTM) are responsible for
current safety standards and regulations regarding automatic vehicular gate operators. To pass certication, all
aspects of gate operator and gate installation must comply with the appropriate safety standards.
For the most up-to-date ASTM F2200 Gate and Fence Standards, refer to www.astm.org.
For UL 325 Safety Standards, refer to www.ul.com.
WARNING
A moving gate or barrier arm, bollard, or wedge can cause serious injury or death. In the following safety information, the
term “gate” refers to the hardware that the automatic gate operator is moving: gate, barrier arm, bollard, or wedge.
To reduce the risk of injury or death:
1. READ AND FOLLOW ALL INSTRUCTIONS. Read the gate operator’s product manual and review all the
product labels and literature prior to installing, operating, or maintaining the automatic gate operator.
2. Never let children operate or play with gate controls. Keep all remote controls, especially radio transmit-
ters, away from children. Do not allow children to play on or around the gate or gate operators.
3. Always keep people and objects away from the gate. NO ONE SHOULD CROSS THE PATH OF THE
MOVING GATE. Start the gate operator only when a gate’s travel path is clear.
4. Test the gate operator monthly. The gate MUST reverse on contact with a rigid object or stop when an
object activates the non-contact sensors. After adjusting the force or the limit of travel, retest the gate
operator. Perform routine tests of the entrapment protection sensors, such as photo eyes and gate edges.
Failure to adjust and retest the gate operator properly can increase the risk of injury or death.
5. Use the emergency release only when the gate is not moving.
SAVE THESE INSTRUCTIONS

Safety-4 D0536 Rev. C StrongArmParkDC: Programming & Operations Manual www.hysecurity.com
6. KEEP GATES PROPERLY MAINTAINED. Read the product manuals. Have a qualied service person make
repairs to gate hardware and replace batteries in accessory or entrapment sensory devices on a regular
basis.
7. The automated gate entry is for vehicle use only. Pedestrians must use a separate entrance. Make sure a
separate walk-through entrance is nearby. Make certain a clear pedestrian path is designated and signs
direct pedestrians to the walk-through gate.
8. Install the supplied WARNING signs on the inside and outside of the gate or barrier gate/operator so they
are clearly visible from both the secure and public sides. Installing the signs is a requirement for UL 325
compliance.
Safety - Additional Installer Responsibility
• Verify the gate operator usage class for the site. For all gate operators other than Crash-rated, refer to Identifying
Gate Operator Category and Usage Class in the product manual. Install the operator only when the gate operator
class is correct for the site, size, and type of gate.
• The gate operator must be properly grounded and the incoming power voltage must match the voltage label on
the junction box.
• Install an automatic operator only on gates that comply with ASTM F2200 Gate and Fence Standards. Screen or
enclose openings in the gate per UL 325 Safety Standards which include:
All horizontal slide gates must guard or screen openings from the gate’s base support to a minimum height of
6 feet (183 cm) above the ground. This must prevent a sphere of 2¼-inches (57mm) in diameter from passing
through an opening in the gate or the adjacent fence that is covered in the gate’s open position.
Physical stops must exist in the gate construction to prevent over-travel in both directions and, for slide gates,
guard posts must be installed to prevent the gate from falling in the event of a roller failure.
• Before attaching the operator to the gate, move the gate or barrier gate in both directions. Make sure it is level and
moves freely. A gate or barrier gate that moves easily reduces strain on operator components. Gravity should play
no part in the opening or closing of a slide gate.
• Never over-tighten a clutch or pressure relief valve to compensate for a stiff or damaged gate.
• Make sure all exposed pinch points, rollers and wheels are guarded.
• Reduce the risk of entrapment throughout the entire travel path by making sure the gate is installed in a location
which ensures the required clearance between the gate and adjacent structures when opening or closing. On slide
gates, minimize the parallel gap between the gate and the fence.
• Install the gate operator on the secure (non-public) side of the gate. Note that swing gates cannot open into public
areas.
• Install external entrapment protection sensors so pedestrians are protected from entrapment in both directions of
gate travel and all hazard areas are fully protected. On hydraulic gates, set the pressure relief valve at the lowest
allowable setting that will reliably operate the gate. The pressure relief valve controls the applied force of the opera-
tor and the sensitivity of the inherent entrapment sensor (IES). Note that no IES exists in the StrongArm operator or
Crash products.
• Never disable the Warn Before Operate buzzer. This buzzer provides an alert that the gate is about to move.
• Mount access control devices beyond reach of the gate. The control devices that operate the gate must:
Be located in a clear line of sight to the gate. Locate controls (Open, Close, Stop/Reset) where a user will have a
clear view of the gate.
Be mounted beyond 6 feet (183cm) of the gate, to prevent users from touching or accessing the gate while
operating the controls. People attempting to access the controls by reaching through or around the gate can be
seriously injured or killed by the moving gate.
Incorporate a security feature to prevent unauthorized use.
Connect radio and other remote access (non-resetting controls) to the RADIO OPTIONS terminal.
SAVE THESE INSTRUCTIONS

www.hysecurity.com Safety D0536 Rev. C Safety-5
Safety - Installer’s Responsibility, continued
• Open and close the gate to conrm that it was properly installed and to ensure reduced risk of entrapment. Verify
the clearance between the gate and adjacent structures per UL 325 Safety Standards. Have a qualied technician
test the gate monthly.
• When you complete the installation, demonstrate the safety features and operation of the gate operator to the end
user:
Clearly explain and demonstrate the consequences of removing or defeating any of the safety features.
Remove the operator cover(s), and then turn the power on and off.
Manually release the gate. (Manually release only when the gate is NOT moving.)
Use the Emergency Stop Button. (If an emergency stop button is not available, show the user where the Stop but-
ton is located on the gate operator.)
NOTE: Gate operator instructions must be given to the owner per UL 325 Safety Standards.
• Take photographs of the completed installation site and save it in your business les.
Safety - Owner/User Responsibility
As the owner/user, you are responsible for the correct and safe installation, operation and maintenance of the
StrongArmPark DC gate operator. It is of the utmost importance that you read and follow the specic instructions
and precautions found in the Important Safety Information addressed in this manual. In addition, you must ad-
here to the safety standards of applicable federal, state, and local safety regulations, industry standards, and/or
procedures.
NOTICE
For installations outside the United States, make sure that you follow the applicable international, regional,
and local safety standards.
• Automatic gates are for vehicular use only; provide and maintain walkways and signs to direct pedestrians to a sepa-
rate walk-through entrance.
• An automatic gate can start at any time without warning; always keep people away from the gate area.
• Never let children operate or play with gate controls. Keep all remote controls, especially radio transmitters, away
from children. Do not allow children to play on or around the barrier arm, gate area, or gate operators.
• Learn how to turn the power on and off. Learn how to manually operate the barrier arm.
• WARNING signs supplied with the gate operator must remain installed and clearly visible on both sides of the gate.
The signs are required to maintain UL 325 compliance.
• Do not physically disable the warning buzzer and NEVER disconnect or
cut its wires. The buzzer provides compliance with the Manual on Uniform
Trafc Control Devices (MUTCD) standards. Disabling the warning buzzer
may increase the risk of death or serious injury.
• Be aware of the length of the barrier arm. Safeguard against any possible
contact between the barrier arm and overhead power or utility cables and
wires.
• Do not remove entrapment devices or any other safety features.
• Have a professional gate installer routinely inspect the gate hardware and test the entrapment protection sensors
and overall gate operation. Have a qualied service person make repairs to gate hardware and equipment to keep
the gate running smoothly.
Be aware of the barrier arm length.
To
reduce the risk of electrocution,
maintain a minimum 10 foot (3 m)
clearance between the barrier arm
and all electrical utility lines and
equipment.

IdentIfYIng gate operator CategorY and usage Class
The StrongArmPark DC operator is approved for all the following classes and, according to UL 325 Safety Stan-
dards, falls in the Slide Gate and Vertical Barrier Arm category for gate operators. Its usage class is determined by
the area that the vehicular gate services.
Four different vehicular usage classes are dened by UL 325:
Class I
Class I: Intended for use in a location of one to four single family dwellings or a parking
area associated with one to four single family dwellings.
Class II
Class II: Intended for use in a commercial location or building such as a multi-family
housing units (ve or more single family units) hotels, garages, retail stores or other
buildings servicing the general public.
Class III
Class III: Intended for use in an industrial location or building such as factories or
loading docks or other locations not intended to service the general public.
Class IV
Class IV: Intended for use in guarded industrial locations or buildings such as an airport
security area or other restricted access location, not servicing the general public, in
which access is monitored by security personnel or via closed circuitry.

CHoosIng seCondarY entrapment proteCtIon
The site designer or installer determines which secondary entrapment sensor devices will be installed with the
StrongArmPark DC operator. The type of entrapment sensor device systems are described below. For a complete
listing of the requirements, see UL 325 Safety Standards.
NOTICE: StrongArmPark DC is equipped with a dynamic reversing sensor similar to a Type A primary device. Any
impediment to gate travel causes the barrier arm to stop and reverse.
Usage Class Primary Type Device Secondary Type Device
Class I, II, III A B1, B2, C, or D
Class IV AB1, B2, C, D, or E
To comply with UL 325, refer to the chart and take the following steps:
1. Select the Usage Class according to the gate’s locale and purpose.
2. The required UL 325 primary Type A sensor is an integral part of the StrongArmPark DC system.
3. Based on the gate’s usage class, choose Secondary Type Devices: B1, B2, C, D, or E.
• To comply using B1 - install non-contact sensors (photoelectric sensor or the equivalent).
• To comply using B2 - install contact sensors (edge sensor device or the equivalent).
• To comply using a Type D device requires a CONSTANT HOLD push-button station. This CONSTANT HOLD
push-button station must be the only device that opens and closes the gate. It can only be used where the gate
and push button station will be monitored by personnel 24 hours a day in full view of the gate area. An automatic
closing device (such as a timer, loop sensor, or similar device) must not be employed. A Warning placard stating,
“WARNING - Moving Gate has the Potential of Inicting Injury or Death - Do Not Start the Gate Unless the Path is
Clear” must be placed adjacent to the gate operator controls.
CAUTION
While compliance is possible with Type C, which is a low force limiting clutch, the StrongArmPark DC
operator does not utilize a clutch, therefore this option is not available.
Similar compliance issues exist with a Type E device (audio warn before operate alarm). A Type E device is
permitted as a means of secondary entrapment protection by UL 325 in Class IV applications, but it is not
recommended by HySecurity because a buzzer warns, but cannot protect against possible entrapment.
HySecurity highly recommends, even for Class IV use, that secondary entrapment protection (edge or photo-
eye sensor) devices be installed to detect possible entrapment.
To avoid risk of entrapment, do NOT install operator within two feet (2 ft, 61 cm) of a rigid object.

Safety-8 D0536 Rev. C StrongArmParkDC: Programming & Operations Manual www.hysecurity.com
WInd load faCtors & sIte prep
Wind load is always a factor when considering the appropriate gate for a particular site. Solid gate panels pro-
duce a larger wind load than gates with slats or open decorative features. If you are installing a gate operator in
high wind areas, the gate design may affect the load on the gate operator. Because wind force acts the same as
an obstruction, it is important that gates be designed to present a relatively low surface area for the wind to push
on the gate panel.
In the case of the StrongArmPark DC, it is always advisable to remove the barrier arm altogether when high winds
are anticipated. Another option is to install a catch post to keep the barrier arm from bending in the wind.
NOTICE: Under certain wind load conditions, damage to the barrier arm or gate operator may occur and is not
covered by the HySecurity Limited Warranty.
StrongArmPark DC incorporates a dynamic reversing sensor into its design. More information about adjusting the
sensitivity can be found in this manual under, “Adjusting the Dynamic Reversing Sensor” on page 5-8. When the
barrier arm encounters an impediment, it sends a signal to the gate operator to stop and reverse direction. This
feature may be falsely triggered in excessively windy conditions.
manual release
NOTICE: Before attempting a manual release, make sure the barrier arm is not in motion.
Make sure and instruct all users how to move the gate manually. Use the Hold
Open toggle switch to raise the barrier arm or, in the case of complete AC &
DC power loss, turn off both AC and DC power switches and lift the barrier
arm to open it.

BreakaWaY arm feature
Every StrongArmPark DC operator comes equipped with a breakaway arm
bracket, which lessens damage to the operator and reduces the cost of arm
replacement due to vehicle hits.
For more information about installing the breakaway arm bracket, review the
StrongArmPark DC Installation Instructions.
dYnamIC reversIng sensor
The StrongArmPark DC provides an integral feature to help prevent entrapment. While closing, if the dynamic
reversing sensor is tripped twice within a specic period of time, it enters safe mode. The operator stops barrier
arm travel. For more information, see “Adjusting the Dynamic Reversing Sensor” on page 5-8.
