FOR THE GTO/PRO SL-1000/2000 AND GTO/PRO SL-1000B/2000B

AUTOMATIC SLIDE GATE OPERATORS

Because automatic gate operators produce high levels of force, all system designers, installers, and consumers
have an obligation to know the potential hazards associated with improperly designed, installed, or maintained gate
operator systems. Keep in mind that the gate operator is just one component of the total gate operating system.
Each component must work in unison to provide the consumer with convenience, security, and safety.

This manual contains various safety precautions and warnings for the system designer, installer, and consumer.
Because there are many possible applications of the gate operator, the safety precautions and warnings contained in
this manual cannot be completely exhaustive in nature. They do, however, provide an overview of the safe design,
installation, and use of this product. CAREFULLY READ AND FOLLOW ALL SAFETY PRECAUTIONS,

WARNINGS, AND INSTALLATION INSTRUCTIONS TO ENSURE THE SAFE SYSTEM DESIGN,
INSTALLATION, AND USE OF THIS PRODUCT.

The precautions and warnings in this manual are identified with this warning symbol.

The symbol identifies the conditions that can result in damage to the operator or its components, serious
injury, or death.

Because GTO automatic gate operators are only part of a total gate operating system, it is the responsibility
of the designer, installer, and purchaser to ensure the total system is safe for its intended use. Bypassing
safety devices or neglecting to use safety devices with the gate operator is NOT acceptable.

TO MANUALLY OPEN AND CLOSE THE GATE, FOLLOW
THE PROCEDURE BELOW:

CAUTION: Disconnect the
operator chain ONLY when the
gate is NOT moving.

1. Lift the quick release pins UP, then
pull them OUT of the chain brackets
(see illustration).

2. Lay the chain down and manually slide
the gate to the desired position.

To prevent unauthorized removal of the
quick release pins, install pin locks (see
accessory catalog) above the quick release
pins in both chain brackets.

IMPORTANT SAFETY INSTRUCTIONS

FOR THE SYSTEM DESIGNER

WARNING: To reduce the risk of injury or death:

1. READ AND FOLLOW ALL INSTRUCTIONS.

2. This operator is intended for use only on vehicular gates. Pedestrians must be supplied with a separate
walk-through gate (see Entrapment Protection on page 6).

3. When designing a system that will be entered from a highway or main thoroughfare, make sure the system
is placed far enough from the road to prevent traffic congestion.

FOR THE INSTALLER

WARNING-To reduce the risk of injury or death:

I. Before Installation

1. READ AND FOLLOW ALL INSTRUCTIONS.

2. Verify this operator is proper for the type and size of gate, and its frequency of use.

3. Make sure the gate has been properly installed and slides freely in both directions. Repair or replace all
worn or damaged gate hardware prior to installation. A freely moving gate will require less force to operate
and will enhance the performance of the operator and safety devices used with the system.

4. All openings of a horizontal slide gate must be guarded or screened to prevent a 21/4 inch diameter sphere
from passing through openings anywhere in the gate. This screen (or guard) must also be installed over the
portion of adjacent fence that the gate covers in the open position (see page 6).

5. Review the operation of the system and become familiar with its safety features. Understand how to
disconnect the operator chain with the quick release pins for manual operation of the gate (see page 1).

6. This gate operator is intended for vehicular gates ONLY. A separate entrance or gate must be installed for
pedestrian use (see page 6). NO ONE SHOULD CROSS THE PATH OF A MOVING GATE.

II. During Installation

1. Install the gate operator on the inside of the property and fence line. DO NOT install an operator on the
outside of the gate where the public has access to it.

2. Be careful with moving parts and avoid close proximity to areas where fingers or hands could be
pinched.

3. Determine the best obstruction sensing setting for this installation. The gate MUST stop and reverse on
contact with an obstruction or when an object activates the non-contact sensors. After adjusting the force
or the limit of travel, retest the gate operator. Failure to adjust and retest the gate operator properly

increases the risk of injury or death.

4. Additional safety equipment such as roller guards and safety edges (or photoelectric sensors) MUST
be installed to prevent bodily injury (see page 6).

2

IMPORTANT SAFETY INSTRUCTIONS

5. Mount access controls away from the gate (minimum distance is 10 feet). The user must have full view
of the gate but be unable to touch it while operating the controls.

6. Secure outdoor or easily accessed gate operator controls in order to prohibit unauthorized use of the
gate.

III. After Installation

1. Review ALL safety instructions with the consumer/end user and explain the basic operation and safety
systems of the entire gate operator system, including disconnecting the chain for manual gate operation.

2. Inform the consumer/end user that servicing of the operator must only be done by an experienced

technician.

3. Attach the warning signs (included) to each side of the gate to alert public of automatic gate operation.
Take a photo of warning signs installed on gate. Record the date of the photo for your reference.

4. SAVE THESE INSTRUCTIONS. Leave IMPORTANT SAFETY INSTRUCTIONS

(included) with consumer/end user.

Entrapment Alarm

(bottom right of control box)

SECONDARY MEANS OF PROTECTION AGAINST ENTRAPMENT

As specified by Underwriters Laboratories Inc. UL 325 (31.1.1), automatic gate operators shall have provisions
for, or be supplied with, at least one independent primary and one independent secondary means to protect against

entrapment. GTO gate operators utilize Type A, an inherent entrapment sensing system, as the primary type of
entrapment protection. The GTO/PRO SL-1000/2000 and GTO/PRO SL-1000B/2000B gate operators have provisions
for the connection of Type B1 and B2 protection to be used as the secondary type of entrapment protection.

1. For gate operators utilizing a non-contact sensor (Type B1) in accordance with UL 325 (31.1.6):

A. Refer to the sensor manufacturer’s instructions on the placement of non-contact sensors for each type of

application.

B. 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.

C. 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.

2. For gate operators utilizing a contact sensor (Type B2) in accordance with UL 325 (31.1.10):

A. One or more contact sensors shall be located at the leading edge, trailing edge, and post mounted edge, both

inside and outside of a vehicular slide gate system.

B. A hard wired contact sensor shall be located and its wiring arranged so that the communication between the

sensor and the gate operator is not subjected to mechanical damage.

C. A wireless contact sensor such as one that transmits radio frequency (RF) signals to the gate operator 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.

The GTO/PRO SL-2000 and GTO/PRO SL-2000B operators are designed to stop and reverse for 2 seconds
when the gate comes in contact with an obstruction or when an object activates the non-contact sensors.
Additionally, these operators are equipped with an audio entrapment alarm which will function if the unit
obstructs twice while opening or closing. This alarm will sound for a period of 5 minutes or until the
operator receives an intended signal (e.g., transmitter signal) and the gate returns to a fully open or fully
closed position.

Keep the remote controls away from children and unauthorized users; store controls where children and
unauthorized users cannot access them.

6. If push buttons or key switches are installed, they should be within sight of the gate, yet located far enough
from the gate (at least 10 feet) so the gate cannot be touched while in operation. Do not operate any control
without watching the movement of the gate.

7. Do not activate your gate operator unless you can see it and can determine that its area of travel is clear of
people, pets, or other obstructions.

THE CONSUMER/END USER

8. If your gate has open rollers, be sure that roller guards have been installed to prevent hands and fingers
from being caught in the rollers (see page 6).

9. It is your responsibility to make sure that the installer posted warning signs on both sides of your gate. If
any of these signs or warning decals become damaged, illegible or missing, replace them immediately.
Contact your installer or GTO for replacements.

10. Verify that electric safety edge sensors (or photoelectric sensors) have been installed (see page 6). These
safety devices should be tested monthly.

11. KEEP GATES PROPERLY MAINTAINED. Have a qualified service person make repairs to the gate
hardware. NEVER REMOVE THE OPERATOR HOUSING.

WARNING SIGNS

The warning signs (above right) must
be installed on both sides of the gate
(see page 7 for details).

ENTRAPMENT PROTECTION

GTO’s internal obstruction settings, even when properly adjusted, may not be sensitive enough to prevent bodily
injury. For this reason, safety devices such as safety edges MUST be installed. Furthermore, a pedestrian gate

must be installed if walk-through traffic is expected near the gate. We recommend the GTO Bulldog Pedestrian
Gate Lock (see accessory catalog) for controlled access.
