3 Introduction

Introduction 4

1. READ and FOLLOW all instructions.

2. The gate operator is intended for use with Class I

vehicular swing gates.

Class I denotes a vehicular gate operator (or system)

intended for use in a home of one to four single family

dwellings, or a garage or parking area associated

therewith.

Install the gate operator only when the operator is

appropriate for the construction and the usage class of

the gate.

3. Gate operating system designers, installers and users

must take into account the possible hazards associated

with each individual application. Improperly designed,

installed or maintained systems can create risks for the

user as well as the bystander. Gate system design and

installation must reduce public exposure to potential

hazards. All exposed pinch points must be eliminated

or guarded.

4. A gate operator can create high levels of force during

normal operation. Therefore, safety features must be

incorporated into every installation. Specific safety

features include safety sensors.

5. The gate must be properly installed and work freely in

both directions prior to the installation of the gate

operator.

6. The gate must be installed in a location so that enough

clearance is provided 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.

7. The operator is intended for use 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. The

pedestrian access shall be located such that persons

will not come in contact with the moving vehicular gate.

8. Pedestrians should never cross the pathway of a

moving gate. The gate operator is not acceptable for

use on any pedestrian gate. Pedestrians must be

supplied with a separate pedestrian access.

9. For an installation utilizing non-contact sensors (safety

sensors), see product manual on the placement of

non-contact sensors (safety sensors) for each type of

application.

a. Care shall be exercised to reduce the risk of

nuisance tripping, such as when a vehicle trips the

safety sensor while the gate is still moving.

b. One or more non-contact sensors (safety sensors)

shall be located where the risk of entrapment or

obstruction exists, such as the perimeter reachable

by a moving gate or barrier.

10. For a gate operator utilizing a contact sensor such as

an edge sensor:

a. 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.

b. 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.

11. Never mount any device that operates the gate

operator where the user can reach over, under, around

or through the gate to operate the controls. Controls

are to be placed at least 6' (1.8 m) from any part of the

moving gate:

• A hard wired control device shall be located and its

wiring arranged so that communication between the

control device and the gate operator is not subject to

mechanical damage.

Safety Installation Information

5 Introduction

To prevent SERIOUS INJURY or DEATH from a moving gate:

• Install warning signs on the front and back of the gate in

PLAIN VIEW.

• Permanently secure each warning sign in a suitable manner

using fastening holes.

12. 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, or easily accessible controls shall have a

security feature to prevent unauthorized use. Never

allow anyone to hang on or ride the gate during the

entire travel of the gate.

13. Each gate operator is provided with two safety warning

placards. The placards are to be installed on the front

and back of the gate where they are plainly visible.

The placards may be mounted using cable ties

through the four holes provided on each placard.

All warning signs and placards must be installed where

visible in the area of the gate.

14. To AVOID damaging gas, power, or other underground

utility lines, contact underground utility locating

companies BEFORE digging.

15. SAVE INSTRUCTIONS.
