WARNING
To reduce the risk of INJURY or DEATH:
- Never let children operate the gate or play around the gate. Keep the remote control away from children.
- Always keep people and objects away from the gate. Cars, people, and other objects should never enter when the gate is closing.
- Verify this operator is proper for the type and size of gate.
- 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.
- Test gate operator monthly. The gate must reverse when it comes in contact with a solid object, or stop when an object activates the non-contact sensors. After adjusting the force or travel limit, re-test the gate operator. Failure to maintain the gate operator properly can increase the risk of injury or death.
- Use the emergency release only when the gate is not moving.
- Keep the gate properly maintained. Read the owner’s manual on how to maintain your gate. Have a certified service technician make repairs or install gate operator hardware.
- The gate entrance should be used for vehicles only. Pedestrians should use a seperate entrance.
- Keep these instructions.

both the opening and closing directions is in accordance with the requirement;
however, a single device is not required to cover both directions.
Additional UL Requirements
- A minimum of two (2) warning signs shall be installed, one on each side of the gate where easily visible.
- The gate must have sufficient room when opening and closing. Swinging gates should open inwards and not into public access areas. The gate must be properly installed and move freely in both directions.
- Install the gate operator only when: 1) The operator is appropriate for the construction of the gate and the usage Class of the gate, 2) All openings of a horizontal slide gate are guarded or screened from the bottom of the gate to a minimum of 4 feet (1.2 m) above the ground to prevent a 2-1/4 inch (57.15 mm) diameter sphere from passing through the openings anywhere in the gate, and in that portion of the adjacent fence that the gate covers in the open position, 3) All exposed pinch points are eliminated or guarded, and 4) Guarding is supplied for exposed rollers, could be UL approved
- The gate must be properly installed and work freely in both directions prior to the installation of the gate operator. Do not over-tighten the operator clutch or pressure relief valve to compensate for a damaged gate.
- For gate operators utilizing Type d protection: 1) The gate operator controls must be placed so that the user has full view of the gate area when the gate is moving, 2) The placard as required by 52.1.1.6 shall be placed adjacent to the controls, 3) An automatic closing device (such as a timer, loop sensor, or similar device) shall not be employed, and 4) No other activation device shall be connected.
- Controls must be far enough from the gate (at least six feet) so that the user is prevented from coming in contact with the gate while operating the controls. 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 lineof-sight of the gate. Outdoor or easily accessible controls shall have a security feature to prevent unauthorized use.
- For gate operators utilizing a non-contact sensor in accordance with 30A.1.1: 1) See instructions on the placement of non-contact sensors for each Type of application, 2) 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, and 3) 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.
- For a gate operator utilizing a contact sensor in accordance with 30A.1.1: 1) One or more contact sensors shall be located at the leading edge, trailing edge, and post mounted both inside and outside of a vehicular horizontal slide gate. 2) One or more contact sensors shall be located at the bottom edge of a vehicular vertical lift gate. 3) One or more contact sensors shall be located at the pinch point of a vehicular vertical pivot gate. 4) A hardwired 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. 5) 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.
Step 1: Determine Location for the Gate Operator
Choose either the Front or Rear Position. If you’re not sure, choose the Front
position.
If you chose Front Position, install the chain using
figure 1. 
If you chose Rear Position, install the chain using
figure 2.
Install the operator INSIDE the property
Install the gate operator on the inside of the property and behind the gate.
DO NOT install the operator on the outside of the gate where the public has
access to it.
Gate Operator Distance from Gate and Base
The gate operator should be 5 inches away from the gate.
The chain should be 5 inches above the base. 
Step 2: Installing the Base
The base, also known as a pad is a raised platform. We recommend using a
concrete base.
- Lay out position of 6 wedge anchors by measuring clearance between anchors and inside edge of gate. Figure 5
- Install underground conduits in area for conduits. Figure 6
Size of concrete base
A minimum of 2″ on each side of the operator is recommended.
CAUTION
Contact local underground utility locating companies before digging more than
12 inches deep to avoid damaging underground power, gas or other utility
lines.
Step 3: Installing the Bracket and Chain
Weld (recommended) both brackets directly on the end of both sides of the
gate.
Chain Position
The chain should have no more than 1 inch (2.5 cm) of sag for every 10 feet
(3m) of chain length.
Chain should not be too tight or too loose. Chain should be straight and not
bent at an angle. If the chain is too loose, remove links from the chain until
you get your desired length.
NOTE: Make sure the chain is straight and not
bent. Incorrect installation can cause the gate operator to malfunction and
potentially get damaged. Figure 8.
Maximum Wire Length
14 AWG – 1,150 ft
12 AWG – 1,850 ft
10 AWG – 2,950 ft
- MUST use UL approved power wires, power wires MUST have a minimum capacity for 15 Amp current.
- All operators MUST be properly grounded in order to prevent an electrical charge. Must use a dedicated circuit for power supply.
- When the power is connected, turn the power switch to the ON position.
Step 5: Open Direction
See which direction your gate opens when viewed from the inside (exit side).
Dip Switch #6 (Figure 10) on the bottom of the gate operator circuit board
controls the open direction.
ON = opens to the right, OFF = opens to the left

Dual Gates Setup – Master/Slave 
This setup is for dual swing gates. A
single button press of the remote control can open both gates.
This requires 2 gate operators. One gate operator is the “Master”, and the
other is the “Slave”.
-
On the SLAVE gate operator circuit board, set dip switch #5 to ON (Figure 1).
-
Press the reset button on the SLAVE gate operator circuit board.
-
A 20 awg cable (or higher gauge) with two conductors is required.
A. Locate the green terminal (Figure 2) on the bottom of the circuit board with the words DATA- and DATA+.
B. Use a flathead screwdriver to release the 2 locks on the top of the green terminal.
C. For conductor 1, connect the DATA+ on the MASTER circuit board to the DATA+ on the SLAVE circuit board.
D. For conductor 2, connect the DATA- on the MASTER circuit board to the DATA- on the SLAVE circuit board.
E. Use the flathead screwdriver to close the two locks on the top of the green terminal.
-
Place the cable underground in an electrical conduit.
-
Make sure all remote controls, photosensors, loop detectors, and any other accessories are installed on the MASTER gate operator, and not the SLAVE. The setup is now complete.

DIP Switch Features
There are 6 dip switches located at the bottom of the circuit board. Each switch has a different feature.
- CL-DELAY: Gate Closing delay, switch to ON position, turn timer to 1- 6 seconds.
- TIMER: 1-60 Timer: Auto activated to close gate upon set time ( 1~ 60 seconds).
- OSC: Remote control priority. Allow remote control to direct gate movement whenever gate is moving in any direction. Use first signal to stop gate, use second signal to move gate to opposite direction.
- 1 PASS: Anti-tailgating system – When ON, after a vehicle has cleared the safety loop, the gate will start to close immediately. If a second vehicle crosses the loop while the gate is closing, the gate will stop. The second vehicle must get off the loop before the gate closes completely.
- SLAVE: Secondary operator activation
- OPEN L/R: Choose gate open direction Left or Right.
Installing Non-Calimet Brand Photosensors
Follow infrared control instructions to connect power. Common
wire is connected to Common pole, signal wire is connected to OPEN or CLOSE
pole.
Note: Check Photo eye connection if hear a long beep from Circuit board
the when motor is ON.
Installing an External Receiver
External connectors are installed on the rear side of mainboard
protector box.
Electronic Reversing Device (ERD)
The Electronic Reversing Device (ERD) is a feature on the circuit board which
detects when the gates comes in contact with an obstruction, causing the gate
to reverse.
The open and close knobs determine the amount of force required to reverse the
gate (figure 21). We generally recommend leaving the knob at 75, or around a
3:00 position. You may adjust the positions based on your needs.
If the gate reverses without touching an obstruction, the ERD is too
sensistive. If the gate does not reverse when it hits an obstruction, the ERD
is not sensitive enough.
Test ERD every 6 months. 
Remote Control & Timer Delay Closing
Remote Control delay closing
- Choose time delay to activate operator between 0-6 seconds by turning knob on DELAY
Auto Close
This allows your gate to automatically close after opening it.
- On your gate operator circuit board in the bottom, turn Dip Switch #2 to the ON position. Figure 22
- On the gate operator circuit board, adjust the delay by turning the second blue knob from 0-60 seconds. Figure 23
Other:
- BAT: 24V external Battery Connector
- LOOP DETECTOR: Only compatible with Calimet Loop detector device.
- RELAY-1: Signal light connector, this light only turns on when door is in motion.
