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 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. Makesurethegatehasbeenproperlyinstalledandslidesfreelyinbothdirections. Repairorreplaceallworn
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 21/4inch 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).
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.

3
IMPORTANT SAFETY INSTRUCTIONS
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. Informtheconsumer/enduserthatservicingoftheoperatormustonlybedonebyanexperiencedtechnician.
3. Attachthewarningsigns(included)toeachsideofthegatetoalertpublicofautomaticgateoperation.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.

IMPORTANT SAFETY INSTRUCTIONS
SECONDARY MEANS OF PROTECTION AGAINST ENTRAPMENT
As specified by Underwriters Laboratories Inc. UL 325 (30A.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 (51.8.4 [h]):
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 (51.8.4 [i]):
A. Oneormore contact sensors shall be located at the leading edge, trailing edge,andpost mounted 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.

Concrete
Be sure the gate is properly installed and slides smoothly before installing the GTO/PRO Slide Gate Operator. The
gate must be plumb, level, and move freely. The gate must not bind or drag on the ground. Never use a wheel
on the gate, because the additional drag and resistance can cause the operator to obstruct.
The diagram below shows a single slide gate installation with recommended safety features. The operator must be
installedonthe insideof thegate.GTOrequiresusingsafetyedgesandrollerguardstohelpreducethepossibility

TO OPEN THE GATE MANUALLY:
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 Master®pin
locks (see accessory catalog) above the
quick release pins in both chain brackets.

CONNECTING THE BATTERY
INSTALLATION OF THE GTO TRANSFORMER
STEP 8
Unscrew and remove the front cover of the control box and slide battery into
position with its terminals to the left (see illustration). Make sure the battery
fits snugly in control box.
Connecttheblackbatteryleadtothenegative(–)terminal,
and the red battery lead to the positive (+) terminal. DO
NOT allow battery leads to touch the control board!
Touching the control board with battery leads can short
circuit the system!
HINT: a dab of household petroleum jelly on
each terminal will help prevent corrosion.
RED WIRE to positive (+)
BLACK WIRE to negative (–)
Choose the electrical outlet into which the transformer will be plugged. Measure the distance from the electrical
outlet to the control box, following the path where the low voltage wire will run (the maximum distance can be no
more than 1000 ft.).
NOTE: Transformer must be connected with no more than 1000 ft. of 16 gauge multi-stranded, dual conductor,
direct burial low voltage wire.

The charts below illustrate the average maximum number of cycles (the “MNC”) in a 24 hour period on a typical
single gate, and is installed such that the motor draws 10 amperes to move the gate.
1) TheMNCfortheGTO/PROSL-2000isroughlycomparabletomostACpoweredoperators,andthetransformer
provided with this operator should handle most high traffic situations. If the battery does not seem to be able to
provide the constant charge required for your application, the addition of the GTO/PRO 40 Amp Hour Battery
Kit (see Accessoy Catalog) should provide ample power to handle any situation. For more information, call
GTO’s service department at 1-800-543-GATE.

2) Ifthe gate is binding or dragging, or if ball bearingrollersarenot used, it will require more than 10 amps tomove
it. This will reduce the MNC.
3) The charts are based on the transformer being plugged into an outlet that provides a line voltage of 120 volts; if
the outlet provides less than 120 volts (for example, some rural areas may only provide 105 volts), it can reduce
the MNC by as much as 50%.
4) A fully charged standard battery has an inherent reserve of 20-50 cycles without requiring a charge. This allows
peak loads at several points during the day, depending upon how much time the transformer has to provide a
charge to the battery between cycles. The transformer is capable of fully recharging the battery in as little as five
minutes at optimum conditions.
5) The charts on page 16 are based upon an ambient temperature of 40º F. Battery performance and speed at which
it will recharge will fluctuate based upon temperature.
6) The MNC for dual gate applications will be about 50% of those for a single gate.
IMPORTANT:
•The GTO transformer is intended for indoor use. If the transformer can only be plugged into
an outside electrical outlet, a weatherproof housing or cover (available at electrical supply
stores) must be used.
•Use of a surge protector is highly recommended.
• Optional Solar Panels are available from a GTO dealer; see Accessory Catalog.
