A. Operation

1. Manual operation: Manual balanced door system. The customized cast iron hydraulic speed control with back checking feature is manufactured by LCN for Wikk Industries, Inc. This unit meets ANSI standards and is designated as a “Grade 1” speed control. Speed control is concealed in the head frame and has latch, general and back check adjustments. The speed control is removable without requiring the removal of the door, head frame or any other structural members of the balanced door system.

2. Automatic operation: Automatic balanced door system. The operating mechanism is the Access-A-Matic. The Access-A-Matic electro-mechanical operator is overhead concealed, and designed, manufactured by and is a product of the balanced door manufacturer, i.e. Wikk Industries, Inc. Operator consists of a 2 stage gear box, permanent magnet motor and electronic control panel. Hydraulic operators or operators containing closing springs are not acceptable. Operator is capable of normal speed or low speed/low energy operation. The low speed /low energy operation allows opening force within the limits of ANSI Standard A156.19. Control panel selection includes Push & Go with sensitivity adjustments, electric lock release functions and early power stage boost closing. Operator and electronic control box mount directly onto guide box in place of the manual speed control and is completely concealed within a minimum size of 5-1/2 inch by 5-1 /2 inch (139.7 by 139.7mm) header without a surface applied drive arm. The door can be manually operated (with power on or off) without damage to the operator. The system is furnished complete with Wikk AccessAbility™ activation switch products, or sensors and safety devices as required.
