18.1.1
Swinging Doors
Automatic Swing Doors have a variety of configurations, including:
• A single door swinging in or out, left-handed or right handed
• A pair of doors simultaneously swinging in the same direction
• A pair of doors simultaneously swinging in opposite directions (double egress)
The door operator is concealed or surface applied. The doors are center pivoted, offset hung, bal-
anced or butt hinged. No matter what the configuration or system, automatic swinging doors shall
include guide rails, sensors or control mats and signage for the safety and convenience of the user.
6. Guide Rails
6.1.1 Two guide rails shall be installed on the swing side of each door. Single doors shall have one
on each side of the door and pairs or double egress shall have one rail on each hinge side. Rails
shall project to the leading edge of the widest door in the open position.
Exception #1: A wall or separator is permitted to be used in place of a rail, provided that it meets
the criteria in 6.2.1 through 6.1.5
Exception #2: Guide rails for swing 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 in.
Exception #3: If double egress doors or a pair of doors is installed in a hallway, no guide rails are
required if the distance between the wall and the door in the 90 degree open position does not
exceed 10 in.
Exception #4: Guide rails for Knowing Act swinging doors serving both egress and ingress shall
project out from the face of the doorjambs on the swing side to no less than the outside leading
edge of the open door plus 12 in.
6.1.2 A guide rail shall be 30 in. high minimum measured from the floor surface.
6.1.3 A guide rail shall have a panel or divider to inhibit access to the protected area.
6.1.4 There shall be 6 in. minimum clearance between the rail and the door in the fully open 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 in. 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 the jamb (or
other adjacent surfaces) of 6 in.
For control mat adjustments, see full standard.
8. Sensors
8.1 General Requirements for Sensors
8.1.1 Activating zones for swinging, sliding and folding doors shall have a minimum width equal
to the width of the clear opening measured at 8 in. and 30 in. perpendicular from the face of the
closed door(s). The length from the face of the door shall be 43 in. minimum measured at the
center of the clear opening. Detection shall be effective to within 5 in. from the face of the door
measured at the center of the clear opening. Exception: If the 43" activating zone length is not
practical due to physical or environmental conditions, it shall be permissible to be reduced to 30
