GATE AUTOMATION INSTALLATION SAFETY

While the manufacturer has designed the system under strict safety standards, it is ultimately the installers responsibility to follow and

comply with national and local laws, codes and safety standards that apply to the mechanical, electrical and operational aspects of the gate

automation system. These include but are not limited to: safety standards established by entities like Underwriters Laboratory (UL), NFPA 70,

or codes and laws stated by corresponding state, county or municipality.

While it may not be compulsory, we highly recommend following UL 325 safety standards.

UL 325 VEHICULAR GATE AUTOMATION CLASSIFICATION

This system can be used in Class I, Class II and Class III applications.

●

CLASS I – RESIDENTIAL VEHICULAR GATE OPERATOR - A vehicular gate operator (or system) intended for use in a home of one-to

four single family dwelling, or a garage or parking area associated therewith.

●

CLASS II – COMMERCIAL/GENERAL ACCESS VEHICULAR GATE OPERATOR - A vehicular gate operator (or system) intended for use

in a commercial location or building such as a multi-family housing unit (five or more single family units), hotel, garages, retail store, or

other building servicing the general public.

●

CLASS III – INDUSTRIAL/LIMITED ACCESS VEHICULAR GATE OPERATOR - A vehicular gate operator (or system) intended for use in

an industrial location or building such as a factory or loading dock area or other locations not intended to service the general public.

●

CLASS IV – RESTRICTED ACCESS VEHICULAR GATE OPERATOR - A vehicular gate operator (or system) intended for use in a guarded

industrial location or building such as an airport security area or other restricted access locations not servicing the general public, in which

unauthorized access is prevented via supervision by security personnel.

UL 325 ENTRAPMENT PROTECTION REQUIREMENTS

For all installation classes, it is required to properly adjust the inherent obstruction sensing system and install warning signs on both sides of the

gate, warning pedestrians of the dangers of the automated gate system. For Class I and Class II installations, it is required to add a non-contact

device, such as a photoelectric eye OR a contact device such as a gate edge. For Class III installations it is required to add a non-contact device,

such as a photoelectric eye, AND a contact device such as a gate edge OR an audio alarm such as a siren, horn or buzzer.

UL325 INSTALLATION RECOMMENDATIONS

1. 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' (1.2 m) above the ground

to prevent a 2-1/4" (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.

c. All exposed pinch points are eliminated or guarded, and guarding is supplied for exposed rollers.

2. 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.

3. 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.

4. The gate must be properly installed and work freely in both directions prior to the installation of the gate operator.

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. Outdoor or easily accessible controls shall have a

security feature to prevent unauthorized use.

6. The Stop and/or Reset (if provided separately) must be located in the line-of-sight of the gate. Activation of the reset control shall not cause

the operator to start.

7. A minimum of two (2) WARNING SIGNS (supplied with the gate operator) shall be installed, one on each side of the gate where easily

visible.

8. 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.

9. 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" (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).
