Installation Location:
When mounting the Door-Aid on the push
side of the door, the unit should be in a vertical position with the
shaft facing down on the hinge side of the door. The shaft should be in
a position to accept the actuator arm centered on the shaft and parallel
to the header of the door. The actuator arm for the unit should be
positioned below and parallel to the header of the door opening. The arm
will ride freely on the top rail without any type of attachment.
Approved Manufacturers:
The following manufacturers are approved
vendors: "Door-Aid Corporation" Other manufacturers shall be
permitted to the extent that they can supply products equal to the
operational effectiveness of the unit specified.
System Operation:
The unit shall be a self-contained unit
operating from buttons or beams both on the inside and exterior of the
door opening. In addition to the unit there shall be a self-contained
door closer either on top of the jamb or in the standard location. The
door closer shall not be tied to or connected to the unit. The unit
shall be totally free and independent from any attachment to the door,
to be only physically attached at the top of the hinged frame of the
specific door opening.
The actuator arm shall have a rubber-type
ball bearing roller mounted at the end that will ride over the surface
of the top rail of the door. The actuator arm will apply pressure to the
surface of the top rail of the door. The actuator arm will move at a
constant predetermined speed and stop if it meets any obstruction while
opening. When its cycle is completed, then the closer will close the
door.
When opening, the door shall open slowly
in compliance with the ADA low energy door opening guidelines. The hold
open delay shall be adjustable for a 0-60 second period to comply with
the needs of the location. The door shall close at a speed of three to
four seconds, the precise time to be required by the specifications of
the door closer. If there is an obstruction within the opening at the
hold open or in the closing mode, the unit shall recycle by holding
and/or reopening by pressing the activator button.
Inspection:
The operational effectiveness of the unit
shall be site tested and verified by the general contractor. The general
contractor shall have present the factory representative and the vendor
for such tests. Any operational deficiencies of the unit shall be
corrected at the time of inspection by the general contractor to bring
such unit to the level and safety required by the manufacturer.
