FAAC Model S450H 24V Hydraulic Swing Gate Operator
1. Install the gate operator only when the following
conditions have been met:
• The operator is appropriate for the type and usage
class of the gate.
• All openings of a horizontal slide gate have been
guarded or screened from the bottom of the gate to
a minimum of 4 feet (1.25 m) above the ground to
prevent a 2.25 inch (55 mm) diameter sphere from
passing through openings anywhere in the gate or
through that portion of the adjacent fence that the
gate covers when in the open position.
• All exposed pinch points are eliminated or guarded.
• Guarding is supplied for exposed rollers.
2. The operator is intended for installation on gates used
by vehicles only. Pedestrians must be provided with a
separate access opening.
3. To reduce the risk of entrapment when opening and
closing, the gate must be installed in a location that
allows adequate clearance between the gate and
adjacent structures. Swinging gates shall not open
outward into public access areas.
4. Before installing the gate operator, ensure that the gate
has been properly installed and that it swings freely in
both directions. Do not over-tighten the operator clutch
or pressure relief valve to compensate for a damaged
gate.
5. User controls must be installed at least 6 feet (1.83
m) away from any moving part of the gate and located
where the user is prevented from reaching over, under,
around or through the gate to operate the controls.
Controls located outdoors or those that are easily
accessible shall have security features to prevent
unauthorized use.
6. The Stop and/or Reset buttons must be located within
line-of-sight of the gate. Activation of the reset control
shall not cause the operator to start.
7. All warning signs and placards must be installed
and easily seen within visible proximity of the gate. A
minimum of one warning sign shall be installed on each
side of the gate.
8. For gate operators that utilize a non-contact sensor
(photo beam or the like):
• See instructions on the placement of non-contact
sensors for each type of application.
• Exercise care to reduce the risk of nuisance tripping,
such as when a vehicle trips the sensor while the
gate is still moving.
• Locate one or more non-contact sensors where the
risk of entrapment or obstruction exists, such as at
the reachable perimeter of a moving gate or barrier.
• Use only FAAC “Photobeam” photoelectric eyes to
comply with UL325.
Important Installation Instructions
WARNING - TO REDUCE THE RISK OF SEVERE
INJURY OR DEATH:
• READ AND FOLLOW ALL INSTRUCTIONS.
• Never let children operate or play with the gate
controls. Keep remote controls away from children.
• Always keep people and objects away from the
gate. NO ONE SHOULD CROSS THE PATH OF A
MOVING GATE.
• Test the gate operator monthly. The gate MUST
reverse on contact with a rigid object or when an
object activates a non-contact sensor. If necessary,
adjust the force or the limit of travel and then retest
the gate operator. Failure to properly adjust and retest
the gate operator can increase the risk of injury or
death.
• Use the manual release mechanism only when the
gate is not moving.
• KEEP GATE PROPERLY MAINTAINED. Have
a qualied service person make repairs to gate
hardware.
• The entrance is for vehicles only. Pedestrians must
use a separate entrance.
• SAVE THESE INSTRUCTIONS.

• Install devices such as reversing edges and photo
beams to provide better protection for personal
property and pedestrians. Install reversing devices
that are appropriate to the gate design and
application.
• Before applying electrical power, ensure that voltage
requirements of the equipment correspond to the
supply voltage. Refer to the label on your gate
operator system.
Usage
• Use this equipment only in the capacity for which it
was designed. Any use other than that stated should
be considered improper and therefore dangerous.
• The manufacturer cannot be held responsible
for damage caused by improper, erroneous or
unreasonable use.
• If a gate system component malfunctions, disconnect
the main power before attempting to repair it.
• Do not impede the movement of the gate, you may
injure yourself or damage the gate system as a result.
• This equipment may reach high thermal temperatures
during normal operation, therefore use caution when
touching the external housing of the gate operator.
• Use the manual release mechanism according to the
procedures presented in this manual.
• Before performing any cleaning or maintenance
operations, disconnect power to the equipment.
• All cleaning, maintenance or repair work must
performed by qualied personnel.
General Safety Precautions
9. For gate operators that utilize a contact sensor (edge
sensor or similar):
• Locate one or more contact sensors where the risk
of entrapment or obstruction exists, such as at the
leading edge, trailing edge, and post mounted both
inside and outside of a vehicular horizontal slide
gate
• Locate one or more contact sensors at the bottom
edge of a vehicular vertical lift gate.
• Locate one or more contact sensors at the bottom
edge of a vertical barrier (arm).
• Locate one or more contact sensors at the pinch
point of a vehicular vertical pivot gate.
• Locate hard-wired contact sensors and wiring so
that communication between sensor and gate
operator is not subjected to mechanical damage.
• Locate wireless contact sensors, such as those
that transmit radio frequency (RF) signals, where
the transmission of signals are not obstructed or
impeded by building structures, natural landscaping
or similar hindrances. Wireless contact sensors shall
function under their intended end-use conditions.
• Use only FAAC MSE MO, CN60 or M60 edge
sensors.

and the efcient operation of the automated system:
• The gate structure must be suitable for automation. Verify that it is
sufciently strong and that its dimensions and weight correspond
to those stated in the technical specications.
• Verify the smooth and uniform movement of leaves, without irregu-
lar friction during the entire travel.
• Verify the good condition of hinges.
• Verify the presence of mechanical limit switches.
• Remove any locks and bolts.
• Carry out any metalwork operations before installing the
automated system.
Fig. 1
The FAAC S450H automated system for swing-leaf gates con-
sists of an electrical pump and an hydraulic piston transmitting
the leaf movement, assembled in a single block.
The model with hydraulic locking can automate leaves up to
6.5 feet long. It does not require the installation of electric
locks and guarantees that the leaf is mechanically locked
when the motor is not in operation. The model without hydrau-
lic locking always needs one or more electric locks to guaran-
tee the leaf mechanically locks. S450H automated systems
have been designed and built to automate swing-leaf
gates. Avoid any other use, whatsoever.

5. ELECTRICAL CONNECTION OF THE ENCODER
The S450H operator is tted with an encoder system. The proper assignment of the leaf to the corresponding encoder depends
on the connection of the two encoder wires (leaf 1- encoder 1; leaf 2 - encoder 2).
THE ENCODER WIRES MUST BE CONNECTED TO THE BUS CONNECTOR OF THE ELECTRONIC EQUIPMENT.
To verify the proper combination LEAF 1 - ENCODER 1 - MOTOR 1 and LEAF 2 - ENCODER 2 - MOTOR 2, refer to the LEDs
on the encoders, as shown in Table 2 and Figures 19, 20 and 21.
To invert the leaf-encoder combination, change the encoder polarity by swapping its wires until the right LEDs are lit.

DL 2: identies the leaf to which the encoder is installed.
If the encoder is installed on leaf 1, the DL 2 LED is ON.
If the encoder is installed on leaf 2, the DL 2 LED is OFF.
DL 3: when blinking at regular intervals, it signals the pulse reading during the leaf
movement. When the gate leaf is stationary, DL 3 is OFF.
If the gate is to be operated manually because of a power failure or an automated system fault, activate the release device.
1. Lift the protection lid (Fig. 18, Ref. a) and insert the key in the lock (Fig. 18, Ref. b).
2. Turn the key 90° clockwise to open the cover and lift it.
3. Turn the release knob (Fig. 18, Ref. c) counter-clockwise until it stops.
4. Open or close the leaf manually.
To restore the normal operation of the automated system, perform the above described operations in reverse order.
Models S450H and SB are not equipped with a release facility because, thanks to the particular conguration of the hydraulic
distributing ange, you do not need to release the operator to manually move the leaf.

The LEDs on the encoder also remain visible when the rear bracket protec-
tion cover is installed.
