Understanding ANSI A156.10 Requirements for Full Energy Swing Doors

Automatic doors have become an essential part of commercial buildings. They offer convenience, accessibility, and safety for everyone who uses them. However, these benefits come with the responsibility of ensuring that these doors are installed and maintained in compliance with industry standards, such as ANSI A156.10.

What is ANSI A156.10?

ANSI A156.10 is a standard created by the American National Standards Institute (ANSI) that outlines the requirements for full energy swing doors. This standard defines the testing procedures and criteria for determining the energy efficiency of these doors.

What are Full Energy Swing Doors?

Full energy swing doors are automatic doors that are equipped with sensors that detect the presence of a person or object and initiate the door's opening and closing cycle. These doors are designed to be full power, meaning that they open faster than their low energy counterparts. In order to provide safe and reliable access for users, ANSI A156.10 sets forth requirements that must be followed for such door operators.

Requirements of ANSI A156.10

ANSI A156.10 outlines several requirements for full energy swing doors. Here are some of the key requirements:

Guide Rails

6.1 Guide Rails for Swing Doors (See Figures A-2, A-4 & A-H)

6.1.1 Two guide rails shall be installed on the swing side of each door. Rails shall project at least to the leading edge ofthe widest door in the fully open position.

Exception #1: A wall or separator is permitted to be used in place ofa rail, provided that it meets the criteria in 6.1.2 through 6.1.5.8

Exception #2: Guide rails for swinging doors serving both egress and ingress shall project out from the face of the door jambs on the swing side to no less than the outside leading edge of the open door plus 55 inches (1400 mm) (See Figure A-2 & A-4).

6.1.2 A guide rail shall be 30 inches (760 mm) high minimum measured from the floor surface.

6.1.3 A guide rail shall have a panel or a divider to inhibit access to the protected area.

6.1.4 There shall be 6 inches (150 rum) maximum clearance between the rail and the door in the fullyopen position or between the rail and the leading edge of the door at the point in its arc of travel when it is closest to the rail. There shall be a 2 inch (51 mm) minimum clearance between the rail at the hinge side and the door in the fully open position.

6.1.5 Free standing guide rails shall have a maximum dimension between the rail and jamb (or other adjacent surface) of 2 inches (51 mm).

8.1.1 Non-swing side activating detection areas shall have a minimum width equal to the width of the door opening less 5 inches (125 mm) maximum from both sides for a total of 10 inches (255 mm) maximum measured at 15 inches (380 mm) and 30 inches (760 mm) perpendicular from the face of the closed door. The length from the face of the door shall be 43 inches (I090 mm) minimum measured at the center of the door opening. Detection shall be effective to within 5 inches (125 mm) from the face of the door measured at the center of the door opening (See Figure A-12A).8.1.2 A safety zone shall be provided on the swing side of all power operated swinging doors.12

8.1.2.1 If an overhead sensor(s) is used to provide a safety zone, the length of the active area shall be effective to within 5 inches (125 mm) of the face of the closed door measured at the center of the door opening. The safety zone shall extend 5 inches (125 mm) minimum beyond the leading edge of the door in the open position when measured at the center of the door opening. The width of the active area measured perpendicular from the face of the closed door shall be the door opening less 5 inches (125 mm) maximum measuring both sides for a total of 10 inches (255 mm) maximum measured parallel to the face of the door at a distance of 15 inches (380 mm) and 30 inches (760 mm) (See Figure A-12A).

8.1.2.2 If a door mounted sensor is used to provide a safety zone, it shall provide an active area 5 inches (125 mm) maximum from the face of the door for the width of the door less 5 inches (125 rum) from the pivot point. A door mounted sensor on either side of the door shall detect a 28 inch minimum (710 mm) high person or equivalent in the swing path, during the opening or closing cycle and shall cause the door to reverse direction, stop or slow down to a maximum latch edge speed of 4 inches per second (100 mm per second) measured within 1 inch (25 mm) ofthe latch edge before any contact is made (See Figure 12B).

8.1.3 Swinging doors serving both egress and ingress shall have a safety zone on the swing side, as defined in 8.1.2 and an activating zone extending an additional 55 inches (1400 mm) from the leading edge o f the door in the open position (See Figure A-12A).

8.1.4 If a sensor is used for activation and a safety control mat is used as a safety zone, the exposed area of the safety control mat shall extend 5 inches (125 nun) minimum beyond the edge of the door in the open position and:

1) extend 5 inches (125 mm) into the non-swing side area of the door measured from the face of the door; or

2) the door opening area shall be provided with a presence sensor that shall be used to prevent a fully open door(s) from closing when a person is in the space between two non overlapping activation or safety detection areas; or

3) the door closing cycle shall have a delay of 4 seconds minimum after the activating area is clear; or

4) be equipped with a door mounted sensor on the non swing side as described in 8.1.2.2.

8.1.4.1 The width ofa safety control mat shall be in accordance with 7.3.1 (See Figure A-12A).

8.1.5 If the distance between the two non overlapping zones exceeds 8 inches (205 mm) when sensors areused to provide both an activation and a safety zones, the door system shall:

1) be equipped with a safety control mat; or

2) be equipped with a presence sensor across the door opening; or

3) have a door closing cycle delay of4 seconds minimum after the activation area is clear; or

4) be equipped with a door mounted sensor on the non swing side as described in 8.1.2.2.

Why is Compliance Important?

Compliance with ANSI A156.10 is essential for ensuring that automatic doors are safe and reliable for all users. Non-compliant doors can pose a risk of injury to users and can result in costly lawsuits for building owners and managers. Additionally, compliance with this standard ensures that automatic doors are energy-efficient, which can lead to significant cost savings over time.
