INSTALLATION 1 Mounting Site Review Review the following items prior to installation and predetermine the solution to any problems which may exist: • Does sufficient space exist for mounting and future servicing of the opener and control box? • Which direction will the gate swing? • Will the gate opener pull the gate open to the inside (Pull to Open)? • Will the gate opener push the gate open to the outside (Push to Open)? • Where will the universal actuator bracket and gate bracket be secured at the hinge
2 Determine Proper Brackets and Opening Method Mounting Brackets Determining which of the brackets will be needed for your installation. The Sentry gate opener is supplied with universal brackets to mount on round or square hinge post ranging in size from 2 3/8” to 6”. Some pieces may not be needed for your installation. The hinge post is the post your gate hinges are attached to. Follow the steps below to identify which of the included brackets will be needed for your installation.
Pull to Open Installation This installation method is the most common where the gate swings into the property/driveway. No matter which way you decide to install the actuator bracket and universal actuator bracket the pivot point below must be located in approximately this position for a pull to open installation. Gate Hinge Center (pivot point) Push to Open Installation This installation method is common where the driveway slopes up entering the property and gate must swing out to avoid interference.
3 Attach Universal Actuator Bracket to hinge post or post being used Mounting hardware needed: • two 3/8” x 16 x 8” carriage bolts • two 3/8” USS flat washers • two 3/8” nylon lock nuts The universal actuator bracket can be installed in many different ways to accommodate your gate opener installation. The pictures here are for reference and your installation might differ. Universal actuator bracket must be securely installed. Drilling through the post is the strongest method.
4 Attach Actuator Bracket to Universal Actuator Bracket The actuator bracket has a 3/8” pre drilled hole that the linear actuator will mount to. This is the pivot point for the linear actuator. In all cases, the universal actuator bracket should be aligned level with a horizontal gate section. (see Mounting Site Review) For a Pull to Open installation - the pre-drilled hole must be located 5” behind the gate hinge and 8” to the inside of the property.
6 Install Gate Bracket to Linear Actuator 7 Install Gate Bracket to Gate (Pull to Open Only) Install manual release pin, gate bracket and manual release clip to linear actuator extension rod end. To determine where the gate bracket will be installed follow these steps: The linear actuator should be connected to the actuator bracket at this point. NOTE - The linear actuator was shipped from the factory set to the fully retracted position. 1. Swing gate to the fully open position. 2.
14.5” 9 Install Sentry Control Box The control box should be installed in a location that will not require the eight foot linear actuator cable to be spliced. If the cable must be spliced, refer to the splicing instructions below. The most common location would be on a fence or wall adjacent to your gate. Avoid placing the control box behind solid metal objects that might interfere with the receiver reception.
10 Sentry Plug N Go Harness The Plug N Go Harness comes preinstalled and should be plugged into the bottom of the charge controller. Plug is color coded. Red connects to positive battery post and Black connects to negative battery post. Once connected, place harness into wire compartment to prepare for battery installation.
12 Install Charging System - AC or Solar For AC Charge Option - Install Transformer Supplied with opener The USAutomatic transformer (PN520008) supplied is a low voltage UL approved transformer for this type of application. The transformer is equipped with a DC plug for easy connection to the charge controller and can easily provide 575 cycles of operation a day without decreasing the battery charge.
13 Connect Charge Device to Charge Controller Charge Device plugs in here (Transformer or Solar Panel Kit) The Sentry gate opener charge controller accepts inputs from either the supplied AC transformer or the optional solar panel. The transformer and solar panel come with a DC plug for easy installation. Once the charge device is selected and installed connect the DC plug into the charge controller “Power In” located in the upper right corner of the charge controller.
15 Install Linear Actuator Cable 16 Sentry Plug N Go Harness Final Installation With the control box installed route the linear actuator cable into the bottom of the control box using the 1 1/4” hole in the rear bottom. Slide the hole plug that is installed on the linear actuator cable into the control box hole and snap in place. If cable length is excessive, coil up and place in the wire compartment of control box. Ensure the length allows for connection to the Sentry control board Gate 1 connector.
Sentry Control Board Information The Sentry control board is capable of operating two gates. If your installation is a single gate you can operate the gate on the Gate 1 or Gate 2 connector. Set control switch “ON” for the connector being used. The Sentry gate opener was shipped with the receiver and entrapment siren already connected to the control board; these connections are plugs that can easily be disconnected.
18 Adjusting Gate 1 and Gate 2 Sensitivity Sensitivity factory setting is on position 5. This setting will work with most gates. Adjust so that when gate is stopped by an object, it stops and reverses direction. If gate stops and reverses for no obvious reason then increase force by slightly adjusting clockwise. If force is set too sensitive false sensing may be observed.
J2 Terminal (Accessory Wiring) Accessories wire to the J2 connector. Insert wire and tighten screw. J2 pin functions are as follows: J2 pin 1 - +12 VDC output for any accessory power needed J2 Terminal (80ma max). J2 pin 2 - Ground connection for any accessory item. J2 pin 3 - Open / Exit sensor input for opening the gate only (N/O connection) J2 pin 4 - Secondary entrapment device input (N/O connection).
22 Install Safety Signs Mount the 2 included safety signs on inside and outside of the gate area so they are clearly visible. 23 Programming Transmitter and Receiver (model 433DSR2LC): Operating frequency 433.92 MHz. Receiver can store up to 42 unique transmitter dipswitch code settings. Transmitter Setup: (It is recommended that the dipswitch code be changed from the default factory setting) Battery Compartment Door 1. Open the battery compartment door and locate the dipswitches. 2.
Verifying Receiver P2 relay is programmed to latching mode: 1. Press the P2 push-button until the green LD light comes on, then release. 2. Green LD light should be flashing. If green LD light is steady, redo the Receiver Programming section above. Resetting receiver P2 relay to momentary mode: 1. Press the P2 push-button until the green LD light comes on, then release. Green LD light should be flashing. 2. While the LD light is flashing, push the P1 push-button down and release.
ENTRAPMENT ZONES Zone 1 The leading edge of the gate & catch post. Zone 2 Area between the gate and hinge post. Zone 3 The arc of the gate or gate path. Zone 4 he space between the gate when open and any obstruction such as fence, wall, T landscaping, etc. Zone 5 The point where two bi-parting gates come together when closing. (Not shown below) Every installation is unique and it is the installer’s responsibility to recognize and remedy all safety concerns.

ut ut The Gate 2 kit contains linear actuator with 1 1/4” hole plug, 50 feet of 5 conductor cable, wire nuts, junction box and mounting hardware. The Sentry control box is equipped with two knock outs for the gate 2 linear actuator cable. One knock out is 1 1/4” and is intended for non conduit installation (not advised). The other knock out is 7/8” and designed for 1/2” conduit fitting for conduit installation (recommended). (see figure) If conduit is being installed knock out 7/8” hole.
17. Cut extension cable to length allowing for future considerations. 18. Remove 2” of cable insulation to expose the 5 wires. Caution: do not damage internal wires. 19. Remove approximately 1/2” of insulation from each wire. 20. Locate 8 pin connector and pigtail previously cut from Gate 2 linear actuator cable. Prepare wires for the splice. 21. Connect the 5 wires from extension cable to the 5 wires from the pigtail by matching the wire colors. Then secure with supplied wire nuts. 22.
Accessories Sentry Garage Door Receiver Part Number 030209 The receiver provided with the Sentry gate opener operates at 433.92 MHZ and might or might not be compatible with your garage door. If receiver frequency is not compatible the optional “Sentry Garage Door Receiver kit” can be easily installed in the garage. The kit contains receiver, transformer and a wire harness that easily installs to the existing garage door. One receiver will be needed for each garage door.
Sentry Photo Eye (Send and receive) Part Number 550012 The photo eye is a secondary safety device. It produces a beam between the 2 units. When the beam is broken it will keep the gate from closing. It requires wires to be connected to both units (20 gauge) for operation. Typically a swing gate needs two sets of photo eyes for the best area protection (see figure below). One set of photo eyes pointing across the drive on the Transmitter Receiver outside of the hinge post (A).
Electric Gate Lock Part Number 070510 The USAutomatic Electric Gate Lock works with an automatic gate operator to securely lock the gate into position without having to step out of a vehicle. The USAutomatic Electric Gate Lock is wired into the gate operator control box, and when an input device such as a transmitter or keypad is used to open the gate, the USAutomatic Electric Gate Lock disengages. The gate will then swing open.
Programming Your Wireless Keypad Part Number 050520 (plastic) and 050550 (metal) This tamper-resistant, weatherproof, programmable Wireless Keypad can be mounted outside your gate and offer convenient access without having to carry a transmitter. Terms to understand: Access Code – The 2 to 5-digit code used to open the gate (24 unique codes are possible). If access code is less than 5 digits it requires the # sign after code is entered. Example: “2 #.” If code is 5 digits the # sign is not required.

Problems 1. Gate 1 or Gate 2 will not operate. Single gate installation. 2. Gate 1 or Gate 2 will not operate. Dual gate installation. 3. Gate 1 and Gate 2 will not operate. Dual gate installation. 4. Single or Dual gate installation opens or closes very slow. 5. Single or Dual gate installation will not automatically close. 6. Single or Dual gate installation automatically opens instead of automatically closing. 7. Gate begins to open or close, but stops and reverses after a couple of seconds.
2. G ate 1 or Gate 2 will not operate. Dual gate Installation 1. These instructions are for the failure of one gate to operate in a dual gate installation. 2. Identify the gate that will not work and check the control switch for that gate and verify that it is turned “ON”. 3. Swap the Gate 1 and Gate 2 linear actuator connectors on the control board. If problem moves to other gate then the control board is bad. 4.
4. G ate 1 or Gate 2 (Gate 1 and Gate 2 if dual gate) operating speed has slowed down When the gate is running slow, the reason is low power. The Sentry charge controller does not output any voltage or current when disconnected from the battery, you cannot check the charge controller by disconnecting from battery and measuring output voltage. To check charge controller output, disconnect from battery, measure battery voltage and note.
6. S ingle or dual gate installation gate auto opens instead of auto closing 1. In this condition the open time can be controlled by adjusting the auto close timer adjustment. 2. If installed in the pull to open configuration then control switch number 2 should be turned “OFF” verify it is. If installed in the push to open configuration verify switch is turned “ON”. 3. Gate is trying to close too far. Readjust close limit adjust for gate 1 or gate 2 to the correct stop position. 4.
9. T ransmitter (remote control) will not operate the gate 1. Remove the J1 connector from the control board and then reconnect, press transmitter button to verify operation. 2. Open the control box and press the transmitter button to operate the gate, listen closely for a clicking sound coming from the receiver. Click should be heard when the transmitter button is pressed if transmitter and receiver programming is correct and they are working correctly a sound should be heard. 3.
10. Photo-eye or other safety accessory will not reverse the gate when closing or hold the gate open 1. The first thing to check is the accessory wiring. See accessory wiring information on page 21. 2. Accessory being used should be wired with the N/O wire connected to J2 pin 5 on the Sentry control board. 3. Verify the control switch “Operating Direction Reverse” switch is set in the correct position, Pull to Open switch is OFF. 4. Connect a wire to J2.
