SAFETY
SAFETY INSTALLATION INFORMATION
1. Vehicular gate systems provide convenience and security. Gate systems are
comprised of many component parts. The gate operator is only one component.
Each gate system is specifically designed for an individual application.
2. Gate operating system designers, installers and users must take into account the
possible hazards associated with each individual application. Improperly designed,
installed or maintained systems can create risks for the user as well as the
bystander. Gate systems design and installation must reduce public exposure to
potential hazards.
3. A gate operator can create high levels of force in its function as a component part
of a gate system. Therefore, safety features must be incorporated into every
design. Specific safety features include:
• Gate Edges • Guards for Exposed Rollers
• Photoelectric Sensors • Screen Mesh
• Vertical Posts • Instructional and Precautionary Signage
4. Install the gate operator only when:
a. The operator is appropriate for the construction and the usage class of the gate.
b. All openings of a horizontal slide gate are guarded or screened from the
bottom of the gate to a minimum of 4 feet (1.2 m) above the ground to
prevent a 2-1/4 inches (6 cm) diameter sphere from passing through the
openings anywhere in the gate, and in that portion of the adjacent fence that
the gate covers in the open position.
SAFETY INSTALLATION INFORMATION
8. Controls intended for user activation must be located at least 6 feet (1.8 m)
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.
Outdoor or easily accessible controls shall have a security feature to prevent
unauthorized use.
9. The Stop and/or Reset (if provided separately) must be located in the line-ofsight of the gate. Activation of the reset control shall not cause the operator to
start.
10. A minimum of two (2) WARNING SIGNS shall be installed, one on each side of
the gate where easily visible.
c. All exposed pinch points are eliminated or guarded, and guarding is supplied
for exposed rollers.
5. The operator is intended for installation only on gates used for vehicles.
Pedestrians must be supplied with a separate access opening. The pedestrian
access opening shall be designed to promote pedestrian usage. Locate the gate
such that persons will not come in contact with the vehicular gate during the
entire path of travel of the vehicular gate.
6. The gate must be installed in a location so that enough clearance is supplied
between the gate and adjacent structures when opening and closing to reduce the
risk of entrapment. Swinging gates shall not open into public access areas.
7. The gate must be properly installed and work freely in both directions prior to the
installation of the gate operator.
11. For a gate operator utilizing a non-contact sensor:
a. Reference owner’s manual regarding placement of non-contact sensor for
each type of application.
b. Care shall be exercised to reduce the risk of nuisance tripping, such as when a
vehicle trips the sensor while the gate is still moving.
c. One or more non-contact sensors shall be located where the risk of
entrapment or obstruction exists, such as the perimeter reachable by a moving
gate or barrier.
12. For a gate operator utilizing a contact sensor such as an edge sensor:
a. One or more contact sensors shall be located 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.
b. One or more contact sensors shall be located at the bottom edge of a
vehicular vertical lift gate.
c. A hard wired contact sensor shall be located and its wiring arranged so the
communication between the sensor and the gate operator is not subject to
mechanical damage.
d. A wireless contact sensor such as the one that transmits radio frequency (RF)
signals to the gate operator for entrapment protection functions shall be
located where the transmission of the signals are not obstructed or impeded
by building structures, natural landscaping or similar obstruction. A wireless
contact sensor shall function under the intended end-use conditions.
e. One or more contact sensors shall be located on the inside and outside leading
edge of a swing gate. Additionally, if the bottom edge of a swing gate is
greater than 6 inches (152 mm) above the ground at any point in its arc of
travel, one or more contact sensors shall be located on the bottom edge.
f. One or more contact sensors shall be located at the bottom edge of a vertical
barrier (arm).

SAFETY
REQUIRED ENTRAPMENT PROTECTION DEVICES
REQUIRED ENTRAPMENT PROTECTION DEVICES
To prevent SERIOUS INJURY or DEATH from a moving gate:
• Entrapment protection devices MUST be installed to protect anyone who may
come near a moving gate.
• Locate entrapment protection devices to protect in BOTH the open and close
gate cycles.
An entrapment zone is every location or point of contact where a person can become entrapped between a moving gate and a stationary object. All gate operator systems
REQUIRE two independent entrapment protection systems for each entrapment zone. This operator contains an inherent (internal) entrapment protection system (the primary
entrapment protection system) and REQUIRES the addition of an external entrapment protection system (non-contact photoelectric sensor or contact safety edge sensor) for
EACH entrapment zone.
Your application may contain one or many entrapment zones. Property owners are obligated to test entrapment protection devices monthly.
CONTACT SENSORS (EDGE SENSORS)
If the electrically activated edge sensor comes in contact with an obstruction while the gate is moving, the gate will stop and reverse. The gate will not be able to travel in that
direction until the obstruction is cleared. Use edge sensor models G65MG0204, G65MGR020, or G65MGS020.
3 Edge Contact Sensor
• Locate entrapment protection devices to protect between moving gate and
RIGID objects, such as posts or walls.
Edge Sensor for Open CycleEdge Sensor for Close Cycle
!
NON-CONTACT SENSORS
If the photoelectric sensor beam gets blocked while the gate is moving, the gate will stop and reverse. The gate will not be able to travel in that direction until the obstruction
is cleared. It is best to use monitored photoelectric sensors, model CPS-UN4. If a monitored photoelectric sensor is not working or loses power or the beam is blocked, then ALL
gate operation in that direction will stop. Unmonitored photoelectric sensor models AOMRON and RETROAB are also acceptable.

IMPORTANT SAFETY INFORMATION
To prevent SERIOUS INJURY or DEATH from a moving gate:
• Pinch points must be guarded at all times. Install enclosed-style gate tracks and
roller guards.
• Place screen mesh 4 feet (1.2 m) high on the gate to prevent access through
openings anywhere the gate may travel.
• Mount controls at least 6 feet (1.8 m) from the gate or ANY moving part of the
gate.
• Install Warning signs on EACH side of gate in PLAIN VIEW. Permanently secure
each Warning sign in a suitable manner using fastening holes.
• This operator is intended for vehicular use only. To prevent INJURY to
pedestrians, a separate pedestrian access should be supplied, visible from the
gate. Locate the pedestrian access where there is not a chance of INJURY at
any point during full movement of the gate.
• Contact sensors MUST be located at the leading and trailing edges, and post
mounted both inside and outside a horizontal swing gate. Non-contact sensors
such as photo eyes MUST be mounted across the gate opening and operate
during BOTH the open and close cycles.
• To AVOID damaging gas, power or other underground utility lines, contact
underground utility locating companies BEFORE digging more than 18 inches
(46 cm) deep.
• Entrapment protection devices MUST be installed to protect anyone who may
come near a moving gate.
• Locate entrapment protection devices to protect in BOTH the open and close
gate cycles.
• Locate entrapment protection devices to protect between moving gate and
RIGID objects, such as posts or walls.
• Too much force on gate will interfere with proper operation of safety reversal
system.
• NEVER increase force beyond minimum amount required to move gate.
• NEVER use force adjustments to compensate for a binding or sticking gate.
• If one control (force or travel limits) is adjusted, the other control may also
need adjustment.
• After ANY adjustments are made, the safety reversal system MUST be tested.
Gate MUST reverse on contact with a rigid object.
• DO NOT touch the heater when switch is on, heater may be hot.
• ALWAYS wear protective gloves and eye protection when changing the battery

SAFETY
STANDARD INSTALLATION
(Inside Property)
The illustration is an example of a standard installation.
COMPACT INSTALLATION
EARTH GROUND ROD
Proper grounding gives an electrical
charge, such as from an electrical
static discharge or a near lightning
strike, a path from which to
dissipate its energy safely into the
earth. Without this path, the intense
energy generated by lightning could
be directed towards the gate
operator. Although nothing can
absorb the tremendous power of a
direct lightning strike, proper
grounding can protect the gate
operator in most cases.
