SAFETY INSTALLATION INFORMATION

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. Install the gate operator only when the operator is appropriate for the construction of the gate and the usage class of the gate. 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. Specifi c 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.

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.

Introduction

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.

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.

14.To AVOID damaging gas, power, or other underground utility lines, contact underground utility locating companies BEFORE digging.

15.SAVE THE INSTRUCTIONS.

Moving Gate Can Cause

Injury or Death

KEEP CLEAR! Gate may move at any time without prior warning.

Do not let children operate the gate or play in the gate area.

This entrance is for vehicles only. Pedestrians must use separate entrance

3 MEASURING AND MARKING FOR THE GATE BRACKET

Before proceeding, begin with the gate in the fully closed position. There are two methods for determining the proper location of the post brackets:

•Paper template (located on the back page of this manual. Must be cut out.)

•Tape measure.

Either method will work depending on preference.

NOTE: Be sure gate is in the closed position before proceeding.

Template Method

Place the template (provided on the back page) under the gate hinge point. Use a screwdriver or dowel rod to temporarily mark the location in front of the gate post.
