Power door operators are becoming a necessity for specific applications in order to provide unrestricted access for people. The Department of Justice Title III Regulations, 28 CFR Part 36, is the Americans with Disabilities Act (ADA). The ADA covers non-discrimination on the basis of disability by public accommodations and in commercial facilities. The ADA requires public accommodations to provide equal access to goods and services for people with disabilities. For locksmiths, non-discrimination includes access into buildings as well as interior doors including public access to offices, hotel rooms, restrooms, etc.
The ADA regulation requires structural and communication barriers be removed in public areas of existing facilities when their removal is readily achievable. In addition, most states have their own regulations regarding accessibility. The ADA requires the use of the more stringent technical requirements for every modification. That is the requirements that provide greater access for individuals with disabilities. It is important to know your state and local codes; they may mandate changes.
One of the major problems for interior doors is the ADA requires a maximum of five pounds force (lbf) in order to open the door. The five lbf door closer requirement cannot be met by some large or heavier doors or even some lighter weight doors because of the attachment method.
Possible solutions include adjusting or replacing the door closer, hinges/pivots, or installing a lighter door or an automatic door opener.
The Arrow 7700 Operator is an electrically powered door opener and closer that functions with a track arm. The Arrow 7700 is designed to operate interior doors weighing up to 150 pounds. The non-handed 7700 is installed onto the pull side of the door. This low energy operator is designed for interior doors in non-fire rated openings. The Arrow 7700 powered door operator is ADA compliant, ETL Listed and meets the requirements of ANSI/BHMA standard A117.1 and ANSI/BHMA A156.19. The Arrow 7700 operates using 120VAC. Power is required to open and close the door.
In the event of power loss, the door will remain in the position at the time of the power loss during the opening or the closing cycles. There is an on-board 24VDC 1.1 Amp power supply and access control interface for powering an electric strike, magnetic lock or mechanical lock (that when powered retracts the latching mechanism) and the hardwired activation switches.
This power operator can be activated with the press of a wall switch, device or manually opening the door. If a wall switch is used, it must be positioned within view of the opening. Switches for the Arrow 7700 power door operator include hardwired and wireless wall switches and radio frequency devices.
The Arrow 7700 Door Operator’s “Push & Go feature senses the movement of opening the door and powers the operator to the full open position. When an activation signal is transmitted from a wall switch or operating device to the power operator, the door will open once the lock’s latch has been retracted or released.
The Arrow 7700 has Obstruction Detection during the opening cycle. If an obstruction is detected during opening, the operator will stop and the motor will reverse closing the door. If no obstruction is detected, the door will stop at the open position. After remaining in the Open Position for an adjustable time of 0 to 30 seconds, the door will begin to close. During closing cycle, the door operator motor closes door using a closing force not exceeding 15 lbf.
I was invited to the installation of an Arrow 7700 Powered Door Operator, Model 7710PRF1.AL. The aluminum finish unit came with a 433 MHz radio frequency receiver and power cord. The door is equipped with a Sargent Profile Series V.G1 standalone electromechanical cylindrical lock.
The decision was made to install the 7700 onto an interior office entry door within a large teaching facility. The office has a drop ceiling with an electrical connection box above the drop ceiling, approximately 10 feet away. The interior office has a right handed, inswing door.
The Detex AO19 is designed for medium to high traffic applications operating doors up to 250 lbs.
