- Positive Hold Open - degree of hold open is predetermined by mounting point
Note: Neither of these options is allowed on fire rated doors.
Positive Stop - Parallel arm has a stop in the soffit shoe to stop the door opening at a specific point; seen on doors where auxiliary stop is required and wall or floor stops are not appropriate
Delayed Action - An optional hydraulic adjustment to delay closing on some models (up to 1 minute) from maximum opening to approximately 75 degrees
Back Check - Standard in some models, optional in others; a hydraulic adjustment to slow the door's opening swing after approximately 75 degrees

ADA Door Control Requirements:
- Door must open to at least 90 degrees
- Low opening force - less than 5 lbs. for interior doors and less than 8 1/2 lbs. for exterior doors
- Slow closing time (the door must still latch)
- Minimum width required - 32" clear opening
Powered Systems - provide easy access for disabled; minimum opening force with adequate closing force
Manual Systems - Must consider door width, opening force, and other factors such as environmental air pressure on opening force
Handicapped door operators
- Doors can be operated manually or automatically; when manually operated, doors operate in the same manner as a non-powered door with closer; automatically operated doors are activated by push buttons, switches, scanners, or radio frequency remote switches
- Manually operated door openers exceed 8.5 pounds of opening force and will not meet ADA requirements.
- Doors can be controlled to remain open for a set time and operate with other doors in a sequential or simultaneous mode; some models have hold open feature for prolonged door opening
- Electric interface available to be used with electric strike or electric latch retraction exit devices; can also be used to interface with access control and exit control, and other security and loss prevention hardware.
