4) The gate must be properly installed and work freely in both directions prior to
the installation of the gate operator. Do not increase the operator amperage
levels beyond the required operable amounts to compensate for a damaged
gate.
5) For gate operators utilizing Type D protection:
•
The gate operator controls must be placed so that the user has full
view of the gate area when the gate is moving,
•
The placard be placed adjacent to the controls,
•
An automatic closing device (such as a timer, loop sensor, or
similar device) shall not be employed
•
No other activation device shall be connected.
6) Controls must be far enough from the gate so that the user is prevented from
coming in contact with the gate while operating the controls. Controls intended to
be used to reset an operator after 2 sequential activations of the entrapment
protection device or devices must be located in the line-of-sight of the gate.
Outdoor or easily accessible controls shall have a security feature to prevent
unauthorized use.
7) All warning signs and placards must be installed where visible in the area of
the gate. A minimum of two placards shall be installed. A placard is to be
installed in the area of each side of the gate and be visible to persons located on
the side of the gate on which the placard is installed.
8) For gate operators utilizing a non-contact sensor such as a photo beam:
•
See instructions on the placement of non-contact sensors for each
type of application,
•
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
•
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:
•
One or more contact sensors shall be located where the risk of
entrapment or obstruction exists, such as at the leading edge,
