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 qualified
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 6 feet (1.83 m) above the ground
to prevent a 2-1/4 inch (57.2 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. Controls intended for user activation must be located
at least six feet (6’) away from any moving part of the
gate and where the user is prevented from reaching
over, under, around or through the gate to operate the
controls.Exception: Emergency access controls only
accessible by authorized personnel (e.g. fire, police, EMS)
may be placed at any location in the line-of-sight of the
gate.
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.
9. For gate operators that utilize a contact sensor (edge
3
Important Installation Instructions (continued)
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 XS 55, CN 60 E edge sensors.

844 OPERATOR
1. DESCRIPTION AND SPECIFICATION
The FAAC Model 844 is an electro-mechanical operator for
sliding gates transmitting motion to the sliding leaf via a rack or
chain pinion appropriately coupled to the gate.
The non-reversing system ensures the gate is mechanically
locked when the motor is not operating and, therefore, no lock
needs to be installed.
The gearmotor is equipped with a mechanical clutch which,
combined with an electronic device, offers the necessary adjustable anti-crushing safety and guarantees stopping or reversing
the gate movement. A handy manual release makes it possible
to move the gate in the event of a power cut or malfunction.
The control board, if supplied with the gearmotor, it is placed
inside the operator.
The 844 automated system is designed and manufactured to
control access of vehicles. Do not use for any other purpose.

4. INSTALLATION
4.1. Preliminary Checks
To ensure safety and an efficiently operating automated system, make sure the following conditions are observed:
• The gate structure must be suitable for automation. For
example, wheel diameter must be in proportion to the
weight of the gate to be automated, an upper guide
must be provided, mechanical stop limits to prevent the
gate derailing must be installed.
• The soil must permit sufficient stability for the concrete pad.
• There must be no pipes or electric cables in the pad
excavation area.
• If the operator is exposed to passing vehicles, install, if
possible, adequate means of protection against accidental impact.
• Check if an efficient grounding is available for connection
to the gearmotor.
4.2. Foundation Plate Installation
1. Assemble the foundation plate as shown in Fig 4. The
foundation plate must be located as shown in Fig 5 (right
closing) or Fig 6 (left closing) to ensure that the rack and
pinion mesh correctly.

2. Prepare a concrete pad as shown in Fig.7, following the
suggested dimensions. It’s recommended to have the pad
a minimum of 4” above level grade to avoid any flooding
of the operator. The underground depth of the concrete
pad is determined by the soil condition and the local
building codes. Make sure the concrete pad is leveled.
3. Provide one or more conduit pathways for all power and
accessory connections. Extend the conduit about of 1/2”
above the level of the concrete pad.
4. After the concrete is poured in the forms and before it
has a chance to set, insert the foundation plate into the
cement and position it flush with the top of the concrete
and aligned with the top of the lower gate frame. Use the
dimensions shown in Figs 5 or 6 to align your foundation
plate. Allow the concrete to set for a minimum of two days
before installing the operator.
5. Route the wires in the conduits. To facilitate the connections allow for about 15” of extra length of cables out of
the conduit. Separate the high and low voltage wires in
different conduits.
