SAFETY » UL325 MODEL CLASSIFICATIONS UL325 MODEL CLASSIFICATIONS I CLASS I – RESIDENTIAL VEHICULAR GATE OPERATOR A vehicular gate operator (or system) intended for use in a home of one-to four single family dwellings, or a garage or parking area associated therewith.
SAFETY » SAFETY INSTALLATION INFORMATION 1. Vehicular gate systems provide convenience and security. Gate systems are comprised of many component parts. The gate operator is only one component. Each gate system is specifically designed for an individual application. 2. Gate operating system designers, installers and users must take into account the possible hazards associated with each individual application.
INTRODUCTION » FEATURES + TOOLS NEEDED + OPERATOR SPECIFICATIONS FEATURES • Full service controller with eight inputs and LED indicators for loops, card reader, radio, etc. • Reversible arm direction for right or left handed operation. • Instant Reverse Device (IRD) monitor senses obstructions during motion. • Fail safe (auto open on AC power failure). • Raise gate input memory will memorize multiple vehicles – ideal for bar code scanners and AVI.
INSTALLATION » INSTALL THE CONCRETE PAD AND CONDUIT INSTALL THE CONCRETE PAD AND CONDUIT 24" Check the national and local building codes before installation. Layout the concrete pad for the operator. The concrete pad should be approximately 24" x 24" x 24" in order to ensure proper and stable operation. The pad should be 6" above the finished grade or even with top of curb (if applicable). NOTE: Pad should always extend below frost line in regions where ground will freeze. 6" 1 18" the conduit.
INSTALLATION » ATTACH THE OPERATOR TO THE CONCRETE PAD ATTACH THE OPERATOR TO THE CONCRETE PAD the operator on the concrete pad and mark the mounting 1 Position holes. 1/2" x 6" wedge anchors in the location of the mounting 2 Install holes. The wedge anchors should be installed with approximately 1-1/4" showing above the concrete pad in order to allow for the 1/2" thick base plate as well as washers for leveling. 3 Attach the operator to the concrete pad with appropriate fasteners.
WIRING » POWER WIRING To reduce the risk of SEVERE INJURY or DEATH: • ANY maintenance to the operator or in the area near the operator MUST NOT be performed until disconnecting the electrical power and locking-out the power via the operator power switch. Upon completion of maintenance the area MUST be cleared and secured, at that time the operator may be returned to service. • Disconnect power at the fuse box BEFORE proceeding.
WIRING » INPUTS INPUTS (J5 TERMINAL STRIP) DO NOT connect ANY device which would deliver ANY voltage of ANY kind to these terminals. The J5 terminal strip is used for controlling the barrier arm with various accessories such as receivers, loop detectors, access controls, and push button stations. Use common and normally open contacts from devices connected to these inputs. The J5 terminal strip is located on the top of the control board. Make connections to the appropriate points for the desired operation.
WIRING » ACCESSORY AND RELAY CONNECTIONS + BATTERY INSTALLATION ACCESSORY AND RELAY CONNECTIONS K1 These terminals will provide battery backed power to 24 Vdc devices and are located at the bottom of the control board at J4 terminals 1 and 2. Terminal 1 is 24 Vdc (+) and number 2 is 0 Vdc (-). Peripheral CLASS 2 low voltage devices that require 24 Vdc power maybe connected here (500 ma. maximum). EXAMPLE: Vehicle detector, radio receiver.
WIRING » PRIMARY/SECOND WIRING FIGURE 1 PRIMARY/SECOND WIRING In a primary/second configuration, either operator can be the primary. Choose an operator to be the primary and then direct all control wiring to it (also install vehicle detectors and receivers in it). At the primary, any input (at J5) with control wires (detectors, receivers, keypads, timers, etc.) to it must also be run to the same terminals of the second.
INSTALL THE RECEIVER » INSTALL THE RECEIVER To prevent possible SERIOUS INJURY or DEATH from a moving gate or garage door: • ALWAYS keep remote controls out of reach of children. NEVER permit children to operate, or play with remote control transmitters. • Activate gate or door ONLY when it can be seen clearly, is properly adjusted, and there are no obstructions to door travel. • ALWAYS keep gate or garage door in sight until completely closed. NEVER permit anyone to cross path of moving gate or door.

Each DIP switch represents the number of seconds the gate will remain OPEN before CLOSING.
ADJUSTMENTS » INSTANT REVERSE DEVICE (IRD) + INSTALL THE BARRIER ARM To reduce the risk of SERIOUS INJURY or DEATH: • Disconnect power BEFORE performing ANY adjustments near drive shaft.
OPERATION AND MAINTENANCE » GENERAL SERVICE + SHEAR PIN REPLACEMENT + BATTERY To avoid SERIOUS PERSONAL INJURY or DEATH from electrocution, disconnect ALL electric power BEFORE performing ANY maintenance. Check at the intervals listed in the following chart: ITEM PROCEDURE Fasteners Check and tighten as required Bearings and Shafts Check for wear and lubricate Battery Maintenance Replace batteries.
ADDITIONAL FEATURES » SUGGESTED LOOP SENSOR LOCATIONS SUGGESTED LOOP SENSOR LOCATIONS Do not allow control devices to be within 10 feet of gate or operator. RECOMMENDATIONS: • If vehicle detectors are used to open or close the gate, use of the presence contacts are recommended. Using the pulse contacts will REDUCE the gate’s safe operation. • If closing timer is to be used, use ONLY on a dedicated free exit. • Close loop must be centered under gate arm.
ADDITIONAL FEATURES » TRAP INSTRUCTIONS TRAP INSTRUCTIONS INSTALL THE K1 AUXILIARY RELAY AND CONNECTOR AT MEGA ARM CONNECTED TO THE ACCESS DEVICE RECONNECT THE POWER AND TEST 1. Reconnect the DC power by replacing the neutral (Black) wire to the battery terminal. 2. Reconnect the AC Power to the operator. 3. To test, activate the following sequence of inputs: • Open the trap gate using the access device. • When the trap gate is open, activate the close loop on the trap operator.
ADDITIONAL FEATURES » SEQUENCE ACCESS MANAGEMENT SYSTEM (SAMS) WITH "MEMORY" SEQUENCE ACCESS MANAGEMENT SYSTEM (SAMS) WITH "MEMORY" NOTE: Insert a jumper across the JP2 terminal to allow the SAMS feature to work with the multiple vehicle memory count selection, use the K1 relay to open the sequenced gate (S1-5 off, S2-6 on, jumper across JP2). This allows gate to store input counts via J5 #4 but not raise the arm until the sequenced slide or swing gate has fully opened.

TROUBLESHOOTING » BATTERY CHECKOUT + GATE NOT OPERATING WARNING - DISCONNECT BATTERIES AND AC POWER BEFORE SERVICING ANY MECHANICAL OR MOVING COMPONENTS. BATTERY CHECKOUT When the batteries become weak the gate will begin to run noticeably slower. NOTE: Batteries should only be checked when you are sure they have had adequate time to fully charge. 1. Turn off the AC power and run gate for 5 to 10 cycles while observing low battery indicator LED D12.
