Prior to installation, the following must be

observed: (per UL 325.56.8.4).

a) Install the gate operator only when:

1. The operator is appropriate for the construction of

the gate and the usage Class of the gate,

2. All openings of a horizontal slide gate are guarded

or screened from the bottom of the gate to a mini-

mum of 4 feet (1.22 m) above the ground to prevent

a 2 1/4 inch (57.2 mm) 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.

3. All exposed pinch points are eliminated or guarded,

and

4. Guarding is supplied for exposed rollers.

b) 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.

c) 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.

d) The gate must be properly installed and work freely in

both directions prior to the installation of the gate opera-

tor. Do not over-tighten the operator clutch or pressure

relief valve to compensate for a damaged gate.

e) For gate operators utilizing Type D protection:

1. The gate operator controls must be placed so that

the user has full view of the gate area when the

gate is moving.

2. The placard as required by 58.1.6 shall be placed

adjacent to the controls,

3. An automatic closing device (such as a timer, loop

sensor, or similar device) shall not be employed,

and

4. No other activation device shall be connected.

f) 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, un-

der, around or through the gate to operate the controls.

Outdoor or easily accessible controls shall have a security

feature to prevent unauthorized use.

g) The stop and/or reset button must be located in the line-

of-sight of the gate. Activation of the reset control shall not

cause the operator to start.

h) A minimum of two (2) WARNING SIGNS shall be in-

stalled, one on each side of the gate where easily visible.

i) For gate operators utilizing a non-contact sensor in ac-

cordance with UL 31.1.1:

1. See instructions on the placement of non-contact

sensors for each Type of application.

2. Care shall be exercised to reduce the risk of nui-

sance tripping, such as when a vehicle, trips the

sensor while the gate is still moving, and

3. 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.

j) For a gate operator utilizing a contact sensor in accor-

dance with 31.1.1:

1. 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 postmounted both

inside and outside of a vehicular horizontal slide gate.

2. One or more contact sensors shall be located at the

bottom edge of a vehicular vertical lift gate.

3. One or more contact sensors shall be located at the

pinch point of a vehicular vertical pivot gate.

4. A hardwired contact sensor shall be located and its

wiring arranged so that the communication between

the sensor and the gate operator is not subjected to

mechanical damage.

5. A wireless contact sensor such as 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 landscap-

ing or similar obstruction. A wireless contact sensor

shall function under the intended end-use conditions.

6. 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 con-

tact sensors shall be located on the bottom edge.

7. One or more contact sensors shall be located at the

bottom edge of a vertical barrier (arm).
