SMART SYSTEMS FOR ACCESS CONTROL
Thank you for purchasing the Zareba Automatic Gate
Opener.
Your Zareba Automatic Gate Opener is designed for
years of trouble free performance. It will provide you
with a comfortable, safe, hassle-free way to access your
property.
The Zareba Automatic Gate Opener is designed to work
on single or dual swing gates. Each individual gate can
be up to 18 feet long and weigh up to 850 pounds.
Your gate opener will work on a variety of gate types
such as iron, tubular, chain link, vinyl, etc. It is not rec-
ommended to use an automatic gate opener on a solid
fence due to wind resistance. Depending on the
strength of the wind and the obstruction sensing, your
gate may not operate properly.
Your Zareba Automatic Gate Opener can be opened
and closed in a variety of ways. Primarily, you will use
your remote transmitter (included with your unit) to
open or close the gate. However, the gate can also be
opened with a hardwired button, an automatic vehicle
sensor, a keypad, or built-in vehicle transmitter systems.
These accessories are discussed later in this manual. The
gate can also be closed with the hardwired button or
keypad. In addition it can be closed automatically using
a time delay that is set in the control box.
Your Zareba Automatic Gate Opener is designed to pro-
vide for safe operation. One of the most important fea-
tures of your gate opener is obstruction sensing. Your
gate opener includes an adjustment for setting the sen-
sitivity of the obstruction performance. When there is an
obstruction that prevents the gate from opening or
closing, the gate will immediately stop and reverse
direction. If the obstruction is removed the gate may be
activated to continue its path from where it stopped. If
the obstruction is not removed, the gate opener will
sound an alarm and will not operate again until the
gate opener system is reset.
There are a number of accessories that can be installed
with your gate opener that maximize your benefit to
owning the system. The accessories include additional
transmitters, keypad, pin lock, solar panel, in-ground
vehicle sensor, and others. Please see the List of
Accessories at end of this manual.
You may obtain additional copies of this manual from
our web site at www.zarebasystems.com, or contact

IMPORTANT SAFETY
INFORMATION
General Safety Information
Vehicular gates are large heavy objects. Automatic gate
openers provide a convenient way to open and close
the gates. Since the gate system and its components
exert a high level of force to open and close the gate,
they can be dangerous, causing severe injuries and
death to you and others.
Your safety and the safety of others depend on the
owner and users of this system to read, understand, and
follow the information and instructions in this manual.
Save this safety information for future use.
Safety overview checklist
WARNING – To reduce the risk of injury or death:
• Use this operator only with single swing gates.
• READ AND FOLLOW ALL INSTRUCTIONS.
• Never let children operate or play with gate controls.
Keep the remote control away from children.
• Always keep people and objects away from the gate.
NO ONE SHOULD CROSS THE PATH OF THE MOVING
GATE.
• Test the gate operator monthly. The gate MUST
reverse on contact with a rigid object or stop when an
object activates the non-contact sensors. After adjust-
ing the force or the limit of travel, retest the gate
operator. Failure to adjust and retest the gate operator
properly can increase the risk of injury or death.
• KEEP GATES PROPERLY MAINTAINED. Read the own-
er’s manual. Have a qualified service person make
repairs to gate hardware if needed.
• The operator is intended for installation only on gates
used for vehicles. Pedestrians must be supplied with a
separate access opening. The pedestrian access open-
ing shall be designed to promote pedestrian usage.
Locate the gate such that persons will not come in
conatct with the vehicular gate during the entire path
of travel of the vehicular gate.
• SAVE THESE INSTRUCTIONS
• Remember that the Zareba Automatic Gate Opener
must only be installed on gate systems meeting the
requirements of the application.
• Ensure that you are using the correct opener for the
type and size of gate, its frequency of use and the
class rating.
• Ensure that the gate and gate opener installation com-
ply with applicable local codes.
• Contact local fire and law enforcement to arrange
emergency access procedures.
• Keep people, animals, and property away from the
gate area. Do not let children play in or near the gate
area.
• Use caution with moving parts to avoid injuring fin-
gers or hands.
• Consider installing contact sensors, or non-contact
sensors to provide additional safety and protection
against entrapment.
• Never activate your gate opener until you ensure that
the area is clear of people, pets, or other obstructions.
Watch the gate until it stops.
• Do not drive forward until the gate stops completely.

Protection Against Entrapment
The Zareba Automatic Gate Opener is designed to com-
ply with UL 325, the safety standard covering automatic
gate opening systems. UL 325 requires that gate open-
ing sytems shall have an inherent entrapment sensing
system and shall have the provisions for, or be supplied
with, at least one independent secondary means to pro-
tect against entrapment. The primary means of entrap-
ment protection in the Zareba Automatic Gate Opener
is Type A, an inherent means of entrapment protection.
The secondary means of entrapment protection in the
Zareba Automatic Gate Opener is Type B2, the provi-
sion for the connection of a contact sensor (edge
sensor).
The gate opener’s built-in means of entrapment protec-
tion (Type A) may not be sensitive enough to prevent
bodily injury in some circumstances. Secondary means
of entrapment protection (Type B2), such as contact
(safety edge) sensors are suggested for enhanced safety.
See page 9 for important information on additional
safety devices.
Entrapment Alarm
(UL 325; 30.1)
In compliance with UL 325 the Zareba Automatic Gate
Opener is designed to stop and reverse direction within
two seconds of sensing an obstruction. In addition, the
Zareba opener activates an audible alarm if the unit
incurs an obstruction twice while opening or closing.
This alarm sounds for five minutes, or until the opener
receives a renewed, intended input from a hardwired
control such as the Push Button Control. At that point
the gate returns to a fully open or fully closed position.
Turning the power switch on the control box OFF and
back ON also deactivates the alarm.
Warning Signs and Labels
Required Safety Precautions for Gates
WARNING SIGNS alert people of automatic gate opera-
tion. They are required when installing the Zareba
Automatic Gate Opener. If pedestrians will be in the
area, install a walk-through gate for their use.
Warning Signs (fig. 3-5)
The warning signs must be installed on both sides of
the gate.
These warning signs and labels must appear at the loca-
tions specified below. If any were missing when the gate
opener was purchased, immediately contact Zareba
Systems for replacements.

SMART SYSTEMS FOR ACCESS CONTROL
Contact Sensors (safety edges) (fig. 6)
Contact sensors are also referred to as “safety edges.”
Activating a properly installed contact sensor while the
gate is moving causes the gate to stop and reverse with-
in two seconds.
Contact sensors must be mounted in compliance with
UL 325, the Underwriters Laboratories safety standard
for gate openers.
Turn off the power switch to the opener
(actuator) before connecting safety device
wiring to the terminal blocks. Unplugging
the transformer does not turn off power to
the opener.
Additional Safety Devices
The Zareba Automatic Gate Opener features built-in
obstruction sensitivity. The opener is designed to stop
and reverse the gate within two seconds of contact with
an obstruction. However, the gate opener’s built-in
obstruction settings, even when properly adjusted, may
not be sensitive enough to prevent injury in some cir-
cumstances. See page 32 for more information.
Safety devices, such as contact (safety edge) sensors or
non-contact (photoelectric) sensors, that stop and
reverse gate direction upon sensing an obstruction are
suggested for additional protection.
Zareba Systems recommends using additional safety
devices. Be sure to use products that are certified and
that comply with applicable UL standards and national
and regional safety codes. Call Zareba Systems at
1-800-272-9877 for information on compatible prod-
ucts for your application.
Important: In all cases, review the safety-device manu-
facturer’s instructions for information on installing these
devices on a vehicular gate.

Non-Contact Sensors (photoelectric beams)
Non-contact sensors, also called photoelectric beams,
enhance safety by monitoring the path of the safety
beam when the gate is closing. Obstructing the safety
beam path activates the non-contact sensor, which
reverses the gate to the fully open position.

Other Items You May Need for Installation
• Low-voltage wire. This is needed to run from the
transformer to the control box. You’ll need enough to
cover the distance between the transformer power
supply and the control box. See Powering Information
on page 34 and Gate Opener Accessories on page 40.
• Solar Panel(s). If your gate is more than 1,000’ away
from an AC power source, you will need at least one
Solar Panel to trickle charge the battery. See Gate
Opener Accessories on page 40.
• Threaded rods or carriage bolts longer than 8”.
You will need these if your fence post is more than 6”
in diameter.
• Reinforcement supplies. If you have thin-walled tube
or panel gates, use wood or metal reinforcement

Overview
This section begins with installation instructions for
gates that open into the property or “pull-to-open”
gates.
NOTE: Gate opener is mounted inside the gate/prop-
erty. A pull-to-open gate will open toward you if you are
standing inside the gated property and facing towards
the gate.
To mount the opener on a brick, masonry, or rock col-
umn, refer to page 28.
If you have a push-to-open gate, you must use a push-
to-open bracket (sold separately). See Push-to-Open
Installation on page 26.
For any installation, having another person assist the
installer is helpful.
Bracket Mounting (fig. 10)
The proper position of the mounting brackets is crucial
to the efficiency and leverage of the gate opener. The
distance between the gate opener (actuator) and the
gate is also determined by the proper position of the
mounting brackets.
NOTE: Ensure a minimum 2” space exists between the
gate and the gate opener (actuator) for safety reasons.
The curved design of the post brackets accommodates
either round or square posts. When mounting the post
brackets, use bolts long enough to pass through the
entire post. When mounting the post brackets to wood-
en posts, use a larger-size washer or metal plate (sold
separately) between the bolts and the wood post to
ensure the stability of the fastening hardware when
thrust is applied.
If you are using gate posts smaller than 6” diameter or
square, they should be (1) made of metal, and (2) set in
cement to ensure the stability of the post.

Gate Reinforcement Methods (fig. 11)
IMPORTANT: Use wood or metal reinforcement plates or
pipes (not included) when mounting the gate bracket to
thin-walled tube gates or panel gates.
Identify the Correct Mounting Positions of
the Gate Bracket and the Post Mount
Bracket Assembly
This section presents instructions for identifying the cor-
rect mounting position of the gate bracket and the post
mount bracket assembly for pull-to-open gates. For
push-to-open gates, see Push-to-Open Installation on
page 26.
NOTE: The direction a gate opens and closes is deter-
mined by standing inside the gated property and facing
towards the gate.
Step 1 (fig. 12)
Assemble the post mount bracket assembly by placing
the pivot bracket between the two post brackets. Insert
the 3/8” x 2” hex bolt through the center hole of the
two post brackets and the pivot bracket. Place a 3/8”
washer, a 3/8” lock washer, and a 3/8” hex nut on the
bottom of the 3/8” x 2” hex bolt and hand tighten.

Step 2 (fig. 13a and 13b)
NOTE: Gate opener (actuator) must be in the fully
retracted position before attaching the gate bracket and
the post mount bracket assembly.
Attach the gate bracket and the post mount bracket
assembly to the gate opener (actuator) by inserting a
clevis pin through the holes in the gate bracket and the
pivot bracket. Secure the clevis pins using the clevis pin
clips.
Step 3 (fig. 14)
With the gate in the desired open position
(from 0° to 110° from the gate’s closed
position) and with the gate opener (actua-
tor) in its retracted position, place the gate
opener (actuator) with the gate bracket
and post mount bracket assembly on to the
gate post and the gate. Position the gate
bracket and the post mount bracket assem-
bly so that the gate opener (actuator) is
level with the horizontal cross member of
the gate.
Tip: Locate the gate opener (actuator) in
approximately the middle between the top
and bottom of the gate. This will prevent
the gate from twisting and flexing. While
holding the gate opener (actuator) in the
desired level position, temporarily secure
with two C-clamps. Use one C-clamp to
temporarily secure the gate bracket to the
gate. Use the other C-clamp to temporarily
fasten the post mount bracket assembly to
the gate post.

Step 4 (fig. 15)
Determine the optimum position of the pivot bracket
on the post mount bracket assembly by ensuring a mini-
mum 2” clearance exists between the gate and the gate
opener (actuator) in both the gate-open and gate-closed
positions. To ensure the 2” clearance minimum is main-
tained in the gate-closed position, remove the clevis pin
from the gate bracket while holding the gate opener;
then close the gate. Move the gate opener (actuator) so
the gate bracket and the gate opener are aligned.
NOTE: Ensure the gate opener (actuator) and the pivot
bracket do not bind in the gate-open and gate-closed
positions.
If the proper clearance cannot be achieved, turn over
the pivot bracket and try a different alignment position.
You may also move the post pivot bracket assembly
slightly to the right or left to obtain the proper
clearances.
After you’ve identified the desired position of the pivot
bracket, place the 5/16” x 1” hex bolt into the desired
pivot hole (out of the five pivot hole options) on the
post bracket.

Step 7 (fig. 17)
Attach the post mount bracket assembly to the gate
post by inserting six 3/8” x 8” carriage bolts though the
post mount bracket assembly and the drilled holes in
the gate post. Fasten each carriage bolt with one 3/8”
washer, one 3/8” lock washer, and one 3/8” hex nut.

Step 5
Mark the bolt-hole locations on the gate and the gate
post. Do this by placing a punch or a mark in the mid-
dle of each bolt slot on the gate bracket and the post
bracket assembly. (Marking the bolt-hole locations in
the middle of each bolt slot permits slight adjustments
to the mounting brackets.)
Once you have marked the bolt-hole locations on the
gate and the gate post, remove the gate bracket and
the post bracket assembly by taking off the C-clamps.
Step 6 (fig. 16)
Using a drill and a 3/8” bit, drill holes through the gate
post and the gate at the marked bolt-hole locations.
NOTE: When drilling holes into the gate post and the
gate, keep the drill level and ensure the holes come out
at 180° on the other side.
