PHI D-4990 User manual

Precision D-4990
Low Energy Door Operator
Product Overview

BACKGROUND
• Low Energy Door Operators are not required by the Americans with
Disabilities Act but can help make facilities more accessible for
people with physical disabilities
• The D-4990 Low Energy Operator is being manufactured by Stanley
Access Technologies and marketed as a Precision Hardware
product
• The D-4990 is not being marketed as a Stanley Door Closer product
so that it will not be confused with low energy operators that Stanley
Access Technologies sells and installs
• The D-4990 utilizes the SAT Magic Force operator to open the door
and a Stanley D-4550 door closer to close the door

With Low Energy
Operators, Safety Rails and
Presence Sensors are not
needed IF THE OPERATOR
IS INSTALLED AND
ADJUSTED CORRECTLY.
Motion detectors, presence sensing devices and pressure pads that will
cause the door to open MUST NOT BE USED.

•KNOWING ACT: Consciously initiating the powered opening of a low-energy door
using acceptable methods including: wall or jamb-mounted contact switches such
as push plates; the action of manual opening (pushing or pulling) a door, and
controlled access devices such as keypads, card readers, and keyswitches.
•LOW ENERGY POWER OPERATED DOOR: A door with a power mechanism that
opens the door upon receipt of a knowing act activating signal, does not generate
more kinetic energy than specified in this Standard and is closed by a power
mechanism or by other means (such as the use of a hydraulic door closer or spring
mechanism).
•POWER ASSIST DOOR: A door with a power mechanism that activates by pushing
or pulling the door, reducing the opening resistance of a self closing door to allow
easier manual opening of the door. If the opening force on the door is released,
the door shall come to a stop and either immediately begin to close, or begin to
close after a predetermined time.
•PUSH-PULL ACTIVATION: A door where the user pushes or pulls a door equipped
with a Low Energy Power Operator to activate a mechanism, causing the door to
go through a complete cycle of automatic opening, hold open time delay, and
closing (“Push and Go”) .
*Excerpted from ANSI/BHMA A156.19-2007
*Consult ANSI/BHMA A156.19-2007 for exact wording and specifications.

•OPENING TIME: Doors shall be adjusted so that the opening time to back-
check or 80 degrees, whichever comes first, must be 3 seconds or longer
as prescribed in ANSI A156.19 Table I, plus Table II.
•TIME DELAY: The doors shall be field adjusted to remain fully open for not
less than 5 seconds.
•CLOSING TIME: Doors shall be field adjusted to close from 90 degrees or
fully open to 10 degrees in 3 seconds or longer as prescribed in ANSI
A156.19 Table I, plus doors should be field adjusted to a minimum of 1.5
seconds from 10 degrees to fully closed.
•FORCE AND KINETIC ENERGY: The force required to prevent a stopped
door from opening or closing shall not exceed a 15 pound force applied 1
inch from the leading edge at any point in its travel. In the event of a power
failure to the operator, doors shall open with a manual force not to exceed a
15 lbf to release a latch, 30 lbf to set the door in motion and 15 lbf to fully
open the door.
•The KINETIC ENERGY of a door in motion shall not exceed 1.25 lbf-ft.
Table Iprovides speed settings for various widths and weights of doors for
obtaining results complying with this paragraph.

DOOR FORCE GAUGE

DOOR FORCE GAUGE

DOOR FORCE GAUGE
When checking for manual opening force
place the tip of the gauge on the push-side
of the door 1” away from the leading edge
and slowly push the door open with the
gauge.
When checking for the opening force
generated by the motor, place the tip of the
gauge on the pull-side door 1” away from
the leading edge, and activate the operator.

T = Time in seconds (this is what we are trying to find)
D = Door Width (inches)
W = Door Weight (pounds)
For doors that are heavier than 200 lbs. we must use the
formula shown below to calculate the Time to Backcheck
and the Closing Time from 90

.
FORMULA FOR HEAVY DOORS
*Consult ANSI/BHMA A156.19-2007 for exact wording and specifications.

Example:
Our door width is 36”. Our door weight is 250 lbs. To calculate the Opening
Time to Backcheck (or 80
0
) and the Closing Time from 90
0
to 10
0
we must
first find the square root of our door weight. The square root of 250 lbs. is
approximately 15.81. Divide 15.81 by 133. This number is approximately
.119. Multiply .119 by the 36” door width. This brings us to the number 4.28
(rounded). 4.28 is our time, in seconds. This number needs to be rounded
up to the nearest half second. 4.5 seconds is the number we are looking
for.
4.5 = Time in seconds
36 = Door Width (inches)
250 = Door Weight (pounds)
4.28 = 36 250 / 133
