PLEASE READ THIS FIRST!

Thank you for purchasing a GTO/PRO-SW2502 When correctly installed and properly used, your GTO/PRO­SW2502 Operator will give you many years of reliable service. Please read the following information to ensure you
have the correct system for your particular needs. This manual will enable you to properly install your GTO/PRO­SW2502 Automatic Gate Operator

The GTO/PRO-SW2502 Operator is designed for installation on pull-to-open gates (gates that open into the
property). By purchasing an accessory bracket, the GTO/PRO-SW2502 Operator can accommodate push-to-open
gates (gates that open out from the property). The gates must not exceed 16 feet in length (per leaf) nor weigh more
than 500 pounds (per leaf) (please see Technical Specifications on page 10). The GTO/PRO-SW2502 Operator
can be used on vinyl, aluminum, chain link, farm tube, and wrought iron gates. Use on solid (wood) gates is not
recommended. Solid surface gates have a high resistance to the wind. If the wind is strong enough, the operator will
obstruct and stop.

The GTO/PRO-SW2502 Operator accommodates extra transmitters, digital keypads, solar panels, push buttons,
automatic gate locks, and other access control products. These optional accessories (see the enclosed GTO/PRO
Accessory Catalog) are available.

The GTO/PRO-SW2502 Operator features adjustable obstruction sensing. This safety feature makes the gate
stop and reverse direction within 2 seconds when it comes in contact with an obstruction.
meaning the gate will exert the minimum force on an obstruction before it stops and reverses direction.

The GTO/PRO-SW2502 Operator also has an adjustable auto-close feature. After the gate reaches the fully open
position, it can be set to remain open up to 120 seconds before automatically closing. Pressing the transmitter button
at any time after the gate opens fully will cause it to close immediately.

For The Consumer

WARNING: To reduce the risk of injury or death:

1. READ AND FOLLOW ALL INSTRUCTIONS. Failure to meet the requirements set forth in the instruction
manual could cause severe injury and/or death, for which the manufacturer cannot be held responsible.

2. 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.

3. The gate must be installed in a location that provides adequate clearance between it and adjacent structures when
opening and closing to reduce the risk of entrapment. Swinging gates

4. The gate and gate opener installation must comply with any applicable local codes.

I. Before Installation

1. Verify this dual opener is proper for the type and size of gate, its frequency of use and the proper class rating.

2. Make sure the dual gate has been properly installed and swings 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 opener and safety devices used with the system.

3. Review the operation of the system to become familiar with its safety features. Understand how to disconnect the
opener for manual gate operation (see page 1

).

must not open into public access areas.

4. This gate opener is intended for vehicular gates ONLY. A separate entrance or gate must be installed for pedestrian
use (see page 6).

5. Always keep people and objects away from the gate and its area of travel. NO ONE SHOULD CROSS THE

PATH OF A MOVING GATE.

Zone 2 – between the gate and the gate post.
Zone 3 – the path of the gate.
Zone 4 – the space between the gate in the open position and any object such as a wall, fence, tree, etc.
Zone 5 – pinch points between the opener and gate or post.

II. During Installation

1. Install the gate opener on the inside of the property and fence line. DO NOT install an opener 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. Devices such as contact sensors (safety edges) and non contact sensors (photo beams) provide additional protection
against entrapment.

4. If push buttons or key switches are installed, they should be within sight of the gate, yet located at least 10 feet from
any moving part of the gate (see diagram below). Never install any control device where a user will be tempted to

reach through the gate to activate the gate opener.

5. Do not activate your gate opener unless you can see it and can determine that its area of travel is clear of people,
pets, or other obstructions. Watch the gate through its entire movement.

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

IMPORTANT SAFETY INSTRUCTIONS

III. After Installation

1. Attach the warning signs (included) to each side of the gate to alert the public of automatic gate operation. It is
your responsibility to post 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 GTO/PRO for free replacements.

2. The gate is automatic and could move at any time, posing a serious risk of entrapment. No one should be in contact
with the gate when it is moving or stationary.

3. Do not attempt to drive into the gate area while the gate is moving; wait until the gate comes to a complete stop.

4. Do not attempt to "beat the gate" while the gate is closing. This is extremely dangerous.

5. Do not allow children or pets near your gate. Never let children operate or play with gate controls. Keep the
remote controls away from children and unauthorized users; store controls where children and unauthorized users do
not have access to them.

6. KEEP GATES PROPERLY MAINTAINED. Always turn power to opener OFF before performing any
maintenance. Clean the push-pull tube with a soft, dry cloth and apply silicone spray to it at least once per month.

7. Service the gate and gate opener regularly. Grease hinges, and replace the battery every 3-5 years.

Secondary Means of Protection Against
Entrapment

As specified by Gate Operator Safety Standard, UL 325 (30A.1.1), automatic gate openers shall have an inherent entrapment
sensing system, and shall have provisions for
against entrapment. The GTO/PRO utilizes Type A
of entrapment protection. Also, the GTO/PRO has provisions for
secondary type of entrapment protection, if desired.

1. For gate operators utilizing a contact sensor (e.g., safety edge sensor– Type B2) in accordance with UL 325 (51.8.4 [i]):

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

outside of a vehicular swing 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 opener is not subjected to mechanical damage.

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

ENTRAPMENT ALARM (UL 325; 30A.1.1A)

The GTO/PRO gate operator is designed to stop and reverse within 2 seconds when the gate comes in contact with
an obstruction. Additionally, these openers are equipped with an
unit obstructs twice while opening or closing. This alarm will sound for a period of 5 minutes, or until the opener
receives an intended signal from a hard wired entry/exit source (e.g. push button control or keypad) and the gate
returns to a fully open or fully closed position. Turning the power switch on the control box OFF and back ON will
also deactivate the alarm. Wireless controls such as transmitters and wireless keypads will not deactivate the alarm.

Required Safety Precautions for Gates

Install Warning Signs

Warning signs alert people of automatic gate operation and are required when installing the GTO/PRO gate operator.
Furthermore, a walk-through gate must be installed if pedestrian traffic is expected near the vehicular gate. We recommend
using the GTO Bulldog Pedestrian Gate Lock (Call the GTO Sales Department) for controlled access.

Entrapment Protection

GTO/PRO SW2502 inherent obstruction settings, even when properly adjusted, may not be sensitive enough to prevent
bodily injury in some circumstances. For this reason, safety devices such as safety edge sensors (or photoelectric sensors),

which stop and reverse gate direction upon sensing an obstruction, are suggested for enhanced protection against entrapment.

Warning Signs

The warning signs (at right) must
be installed on both sides of the
gates (see page 7 for details

).
