C. The gate must be installed in a location so that enough clearance is supplied between the gate and adjacent
structure-es when opening and closing to reduce the risk of entrapment.
D. The gate must be properly installed and work freely in both directions prior to the installation of the gate opener.
Do not over-tighten the opener clutch or pressure relief valve to compensate for a damaged gate.
E. For gate openers utilizing Type D protection:
1) The gate opener controls must be placed so that the user has full view of the gate area when the gate is moving.
2) The placard provided marked in letters at least 1/4-in (6.4-mm) high with the word ″WARNING″ and the
following statement or the equivalent: “ Moving Gate Has the Potential of Inflicting Injury or Death – Do Not
Start Gate Unless Path is Clear” 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.
4) No other activation device shall be connected.
F. Controls intended for user activation must be located at least ten feet 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.
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 opener to start.
H. A minimum of two (2) WARNING SIGNS shall be installed, one on each side of the gate where easily visible.
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 nuisance tripping, such as when a vehicle trips the sensor while the
gate is still moving in the opening direction.
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.
I. For a gate opener utilizing a contact sensor in accordance with Usage Class:
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 post-mounted 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 opener is not subjected to mechanical damage.
5) A wireless contact sensor such as one that transmits radio frequency (RF) signals to the gate opener 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.
6) One or more contact sensors shall be located on the inside and outside leading edge of a sliding gate.
Additionally, if the bottom edge of a sliding 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.
Caution
➢Be sure that the opener is installed in a level and paralleled position and is properly secured.
➢Improper installation could result in property damage, severe injury, and/or death.
