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.
8.1.2 Motion sensors shall detect a 28 in. minimum high person,
moving at a rate of 6 in. per second minimum toward the center
of the door within the detection zone described.
8.1.3 Presence sensors shall detect a stationary 28 in. minimum high
person within the detection areas described for a minimum of 30
sec.
8.2 Swinging Doors
8.2.1 Swinging doors shall have an activating zone as described in
8.1.1.
8.2.2 A safety zone shall be provided on the swing side of all power
operated swinging doors.
8.2.2.1 If an overhead sensor(s) is used to provide a safety zone, the
length of the active area shall be effective to within 5 in.
from the face of the closed door measured at the center of
the door opening. The safety zone shall extend 5 in.
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
in. maximum measuring both sides for a total of 10 in.
maximum parallel to the face of the door at a distance of 8
in. and 30 in.
When the safety zone is occupied by a 28 in. minimum high person
fully in the swing path of a fully open or closed door, the door oper-
ator shall not operate.
8.2.2.2 When an overhead sensor is prevented from providing a
safety signal to the control during the closing cycle, an
additional sensor, sensors or photo beam shall be used to
either (1) inhibit reopening of the door until the safety zone
is cleared or(2) stop, reverse or slow to a maximum latch
edge speed of 4 inches per second measured within 1 inch
of the latch edge before any contact is made.
