IMPORTANT SAFETY INFORMATION
Important Safety 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 qualied service person make repairs to gate
hardware.
• The entrance is for vehicles only. Pedestrians must
use a separate entrance.
• SAVE THESE INSTRUCTIONS.
Important Installation Instructions
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.

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.
Gate Construction
Vehicular gates should be constructed and installed
in accordance with ASTM F2200: Standard Specication for Automated Vehicular Gate Construction.
For more information, contact ASTM at: www.astm.org
Installation
• If you have any questions or concerns regarding the
safety of the gate operating system, do not install the
operator and consult the manufacturer.
• The condition of the gate structure itself directly
affects the reliability and safety of the gate operator.
• Only qualied personnel should install this equipment.
Failure to meet this requirement could cause severe
injury and/or death, for which the manufacturer
cannot be held responsible.
• The installer must provide a main power switch that
meets all applicable safety regulations.
• It is extremely unsafe to compensate for a damaged
gate by increasing hydraulic pressure.
• 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 qualied personnel.

Installing the Warning Signs
This FAAC swing gate operator is supplied
with two warning signs to alert people that a
possible hazard exists and that appropriate
actions should be taken to avoid the hazard or
to reduce exposure to it.

Model 770 24V Underground Swing Gate Operator
1. DESCRIPTION AND CHARACTERISTICS
The FAAC 770 is an electromechanical operator for swing
gates. It is designed for underground installation and therefore
does not alter the appearance of the leaf.
The supplied foundation box allows you to setup the gate
before actually installing the operator.
The 770 electromechanical operator is irreversible, so it ensures a mechanical stop and eliminates the need to install an
electric lock.

3. Carefully weld the guide bracket to the support bracket
(Fig. 11).
4. Fit the gate into the guide bracket and x the top hinge in
place.
IMPORTANT: To ensure trouble-free operation, do NOT weld
the gate leaf to the guide bracket or to the support bracket.
5. Manually verify whether the gate opens and closes completely and smoothly, stopping at the mechanical travel
stops.
2. Prepare the guide bracket, as follows:
• Use a “U” prole with dimensions indicated in Fig. 9.
