Gate Operator Classifi cations
All gate operators can be divided into one of four different
classifi cations, depending on their design and usage. Install
this gate operator only when the operator is appropriate for
the construction and usage class as defi ned below:
• Class I Residential Vehicular Gate Operator
A vehicular gate operator intended for use in a home or for one to
four single family dwellings with a common garage or parking area
associated with these dwellings.
• Class II Commercial / General Access Vehicular Gate Operator
A vehicular gate operator intended for use in a commercial location
or building such as a multi-family housing unit of fi ve or more single
family units, hotel, retail store or other building servicing the general
public.
• Class III Industrial / Limited Access Vehicular Gate Operator
A vehicular gate operator intended for use in an industrial location
or building such as a factory or loading dock area or other location
not intended to service the general public.
• Class IV Restricted Access Vehicular Gate Operator
A vehicular gate operator 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.
Linear barrier gate operator models SG and SG-D meet
the requirements for all four classifi cations.

IMPORTANT INSTALLATION SAFETY INSTRUCTIONS
TO REDUCE THE RISK OF SEVERE INJURY OR DEATH
TO PERSONS, REVIEW THESE INSTALLATION SAFETY
STEPS BEFORE PROCEEDING
1. READ AND FOLLOW ALL INSTALLATION INSTRUCTIONS.
2. Read the blue "Safety Instructions" brochure enclosed with the
packet of information. If any pages are missing or are unreadable,
or you do not have the safety instructions, please call Linear at
1-800-333-1717 to request additional copies.
3. ALL ELECTRICAL CONNECTIONS TO THE POWER SUPPLY MUST
BE MADE BY A LICENSED ELECTRICIAN AND MUST OBSERVE ALL
NATIONAL AND LOCAL ELECTRICAL CODES.
4. A separate power-disconnect switch should be located near the
operator so that primary power can be turned off when necessary.
5. Never connect a button station within reach of the barrier gate or on
the side of the gate operator.
6. Do not adjust the operator controller's current sensing feature too
high. It should be adjusted high enough to keep the gate from falsely
triggering the sensing, but no higher than necessary for the gate to
operate. DO NOT DEFEAT THE PURPOSE OF THIS FUNCTION!
7. You must install all required safety equipment.
8. UL325 Compliance requires the use of contact edges or photoelectric
controls on all automatic or remotely-controlled gate operators.
9. 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 into contact with the vehicular gate during the entire path
of travel of the vehicular gate.
