Specifications: SlideDriver 50VF2/3 (222 X3 ST) be performed in a neat and professional manner, completed to journeyman standards. B. Current safety standards require the use of multiple external sensors to be capable of reversing the gate in either direction upon sensing an obstruction. See also 2.2D. C. Vehicular gates should never be used by pedestrians. A separate pedestrian gate must always be provided when foot traffic is present. D. Gate must have physical stops to prevent over travel in both the open and close directions. E. Current safety standards require gate operators to be designed and labeled for specific usage classes. 1. HySecurity model SlideDriverT"" 50VF2/3 (222 X3 ST) is listed for use in UL 325 Usage Classes I11 and IV only. 1.6. PRODUCT DELIVERY AND STORAGE A. Comply with 01600. B. Store products upright in the original shipping containers, covered, ventilated and protected from all weather conditions. 1.7. WARRANTY A. Provide a warranty against all defects in materials or workmanship for five years or 500,000 gate cycles (whichever occurs first) after the date of installation. Defective materials shall be replaced at manufacturer's discretion with new or reconditioned materials furnished by the manufacturer, at no cost to the owner. Freight, labor and other incidental costs are not covered under the factory warranty, but may be covered by a separate service agreement between installing company and the owner. 1. To ensure validation of warranty, complete warranty registration form online at www.hysecurity.com/warranty. Warranty registration form is also included in the printed materials shipped with the operator. PART 2 — PRODUCTS 2.1. GATE OPERATORS A. HySecurity gate operator model SlideDriver 50VF2/3 (222 X3 ST) with Smart Touch Controller, or other comparable operator, as approved by the architect or specifier. Substitute operators that are approved will be published in an addendum, not less than ten days prior to bid opening. Requests for substitution will include the amount of savings to be passed on to the owner. 2.2. OPERATION A. Operation shall be by means of a metal rail passing between a pair of reinforced composite wheels with polyurethane treads. Operator motors shall be hydraulic, geroller type, and system shall not include belts, gears, pulleys, roller chains or sprockets to transfer power from operator to gate panel. The operator shall generate a minimum horizontal pull of 300 lb (136 kg) without the drive wheels slipping and without distortion of supporting arms. Operator shall be capable of handling gates weighing up to 5,000 Ib (2,268 kg). The operator shall be speed controlled by an electronic Variable Frequency Drive (VFD) which will accelerate and decelerate the gate gradually to prevent shock Toads to the gate and operator assembly. The maximum gate velocity of the SlideDriver 50VF2/3 shall be selectable between 2.2 ft/s (670 mm/s) and 3 ft/s (914 mm/s). The operator shall contain an Emergency Fast Operation (EFO) mode wherein a separate continuous input allows the operator to override all safety inputs and run at the EFO speed. The gate velocity during Emergency Fast Operation (EFO) shall not be less than 3 ft/s (914 mm/s). Upon starting, the VFD will gradually accelerate the gate to its maximum speed and when stopping, gradually reduce gate velocity to less than 1 ft/s (304 mm/s), whereupon a limit switch will stop the electric motor. Two adjustable hydraulic brake valves (one for each direction) assist in slowing the gate to a precise stop. B. Minimum standard mechanical components: 1. Supporting arms: Cast aluminum channel. Arms shall incorporate a fully bushed, 1 1/2" (38 mm) bronze bearing surface, acting on arm pivot pins. (item 2 below) 2. Arm pivot pins: 3/4" (19 mm) diameter, stainless steel, with integral tabs for ease of removal. 3. Tension spring: 2 1/2" (63 mm) heavy duty, 800 Ib (363 kg) capacity. 4. Tension adjustment: Finger tightened nut, not requiring the use of tools. 5. Drive release: Must instantly release tension on both drive wheels, and disengage them from contact with drive rail in a single motion, for manual operation. www.hysecurity.com Specification D0677
