156.19 Compliance Overview*

Information - A156.19 ¦ Low Energy Operator vs
Minimal Requirements for Low Energy Door Operators
Special Concerns Not Covered by A156.19
Information - A156.19*
Compliance with American National Standard A156.10 and A156.19 is
intended to reduce the chance of injury to pedestrians and wheeled
traffic. Most all local codes, such as BOCA, require compliance with
A156.19 if low energy automatic doors or low energy door operators are
used. ANSI states that these are suggested standards, but compliance is
required when local building codes incorporate A156.19. Eastern Door
Service has provided you with our general overview and interpretation of
A156.19. You should obtain and thoroughly read an actual copy of A156.19
- 2007 available from the American National Standard Institute, 1430
Broadway, New York, NY 10018. They are also available
for purchase online at TechStreet™ for a nominal charge.
Energy Operators vs Power Assist
A156.19 provides minimal standard for two types of swinging
door operating equipment. Low energy door operators are a fully
automatic door system, which will open the door completely, without
additional manual force required by the door user. Power assist door
operators only reduce the amount of force required to open a door. The
user must manually operate a door equipped with a power assist operator.
The Americans with Disabilities Act of 1990 exempts automatic and power
assist doors from maneuvering
clearances required by manually operated doors.
Because power assist door
operators require manual opening force, Eastern Door Service does not
recommend their use at accessible entrances. Especially where wheelchair
maneuvering clearances do not exist. Power assist door operators may
meet the letter of the ADA code, but we do not believe these type of
door operators meet the spirit and intent of the ADA. Therefore we do
not discuss the minimal requirements for power assist door operators in
Low energy door operators
comprise most all types of accessible entrance operator systems. Low
energy door operators are usually suitable for every type of accessible
Requirements for Low Energy Operators
Swinging doors equipped with a low energy door operator must
comply with the following minimal standards to comply with A156.19 -
- The door must not open
to the backcheck position (80 degrees) in less than 3 seconds.
- The door must not
fully open (90 degrees) in less than 4 seconds.
- The door must not
close from the full open position to the latchcheck position (10
degrees) in less than 3 seconds.
- The door must not
close from latchcheck position to the full closed position in less
than 1.5 seconds.
- If a presence sensing
device is not used to hold the door in the full open position, a
minimal time delay of 5 seconds is required, before the door begins
- The force required to
stall an opening or closing door shall not exceed 15 lbf (67 N),
when applied 1" from the latch edge of the door.
- The kinetic energy of
a door in motion shall not exceed 1.25 lbf-ft (1.69 Nm).
- Manual opening forces,
in the event of a power failure, shall not exceed 15 lbf (67 N) to
release a latch mechanism if present, 30 lbf (133 N) to set a door
in motion, and 15 lbf (67 N) to open the door completely.
Concerns Not Covered by ANSI A156.19
Some entrances have very high wind or stack pressure
conditions. Because they are what they imply (low energy door
operators), we recommend you consider door operators with more operating
power and spring closing forces, at entrances with these type of
conditions. These types of automatic pedestrian door operators are
covered by ANSI A156.10.
A156.19 does not preclude
any type of actuation device, however it is strongly recommended by
Eastern Door Service that a knowing act, such as a wall switch, is used
to actuate low energy door operators. We do not recommend unknowing acts
of actuation for low energy door operators, such as motion detectors,
unless a safety presence detection device is used on the swing side of
the door. We strongly recommend compliance with ANSI A156.10, when an
unknowing means of actuation is used.
