PART 2 - PRODUCTS

2.1 VEHICULAR SWING GATE OPERATOR AND KEYPAD

A. Model SWD battery back-up swing gate operator as designed by Operator Specialty Company, Inc. (OSCO) shall open and close swinging gates, providing convenience and security. This model is adapted to function with most accessories including: radio controls, single and three button control stations, digital keypads, coded cards, sensing loops, telephone entry systems, and revenue control equipment. The SWD utilizes 115 Volt AC single phase power, converting to 24 Volt DC to power motor and controls.

B. Model AM-KP keypad with gooseneck requires no programming on this unit.

Simply unlock the faceplate and install the program cartridge. When a card is inserted, if the facility codes match, the gate will open.

2.2 DESIGN CRITERIA

A. Keypad specifications shall be as follows:

a. For outdoor use.

b. Programmable downlighting.

TS - 5

c. Cast aluminum, environmentally protected housing.

d. Dimensions: 4” W x 5.5” H x 3” D

B. Operation shall be by means of a 1/2 horsepower 24 Volt DC motor via a single phase dry-type 250VA transformer, transferring power through a one and a half inch pulley and V-belt to a seven inch pulley. Next power transfers through a right angle oil bath gear reducer to a #40 sprocket and chain to another #40 sprocket located on a one inch solid steel drive shaft. The shaft is equipped with a solid steel arm crank and harmonic action articulating swing gate arm attached to the gate.

C. The articulating arm shall cycle the gate through a 90 degree opening in approximately 11-14 seconds using manufacturer recommended installation. By use of an articulating arm design, the gate will start moving slowly, gradually increase in speed, then slow down again as it approaches full open. Larger opening angles and non-standard installation may be achieved through the adjustment of arm components during the installation process.

2.3 COMPONENTS

A. Standard mechanical components shall include as a minimum:

a. 3/16 inch thick, weather resistant UV stabilized polyethylene one piece cover which is fully removable and lockable.

b. Gasketed and powder coated steel cabinet door which is removable and lockable.
