Automatic Operators

The basic design concept for all LCN automatic operator systems considers both the opening and closing motion of the door. LCN designs allow the system to be easily retrofitted into existing doors and frames as well as new construction. A basic LCN electrohydraulic/pneumatic system consists of an automatic operator that incorporates

a heavy duty LCN 4040XP Series door closer and peripheral actuators.

LCN electromechanical automatic operators
utilize a motor gearbox and a control box to perform the opening and closing function. LCN offerings include
electrohydraulic, electromechanical Benchmark, electromechanical Senior Swing and pneumatic low energy automatic operators.

LCN automatic door operators have been improving accessibility in schools and health care facilities for decades. They are ANSI and UL certified and do not require AADM certified technicians. All automatic operator systems are easily retrofitted into existing doors and frames, as well as new construction. Low energy electrohydraulic and pneumatic automatic operators feature a heavy duty closer with a slow opening function. Electromechanical automatic operators utilize a motor gearbox and control box to perform the opening and closing function.

What is the ADA

The ADA is a civil rights law, not a building code. This act is designed to provide protection for people with disabilities. The law is divided into four major titles that prohibit discrimination against the disabled in Employment, Title I, Public Services and Transportation Title II, Public Accommodations Title III, and Telecommunications Title IV. Title III concerns doors and door controls.

The intent of ADA, Title III

Essentially, businesses of all types must comply with accessible design standards to provide people with disabilities with access equal to, or similar to, that available to the general public. Businesses that serve the public must also remove barriers to existing facilities where readily achievable. The deadline for compliance was January 26, 1992.

The final rules implementing Title III were published in the Federal Register of July 26, 1991. To obtain a copy or ask questions, contact the U.S. Department of Justice. Technical information can be obtained from The U.S. Architectural and Transportation Barriers Compliance Board.

How ADA affects doors

The ADA requires an “accessible” opening which means, among other things, providing a door with a minimum 32" (813 mm) clear width opening, easily manipulated handles, a maximum opening force, a minimum closing time, and the capability to open to at least 90°.

ADA criteria, based on opening force, are similar to American National Standards Institute (ANSI) Standard A117.1. This is different from ANSI Standard A156.4, which is based on closing force.
