Another method of activating the door is with the
Push and Go
feature.
This is a standard field selectable option which
activates the door when it is opened more than one inch. It can
be used as the only method of door activation, or it can be used
in conjunction with other external activation means, such as push
buttons. The push and go type activation is intended for
openings that are dedicated to accessibility, since the door is
operating automatically 100% of the time. The push and go
feature is only active when the door is in the fully closed position.
The ED800 has an
open trigger
to activate the door opening.
The ED800 also has a standard
vestibule function
available.
With this function two units can be interconnected. Upon the
completion of the closing cycle of the first unit, an activation
signal will be sent to the second unit. This activation functions in
both directions. If the interior door is activated first, it will then
signal the exterior door to open. If the exterior door is activated
first, it will then signal the interior door to open.
The ED800 also has a standard
latch delay function.
This is
used to control the release of an electric strike, magnetic lock or
the retraction of an electric latch, in conjunction with the
operation of the ED800.
When the ED800 is activated, Form-C relay (NO/ C / NC)
contacts (PINS 6, 7, 8) momentarily change state for up to 1
second to release a strike, magnetic lock or retract a latch.
If required, ED800 operation may be delayed by 1/2 second
when using an electric strike, magentic lock or latch retraction.
Delaying the operator allows a locking device time to release the
door before the ED800 opens it. The delay is enabled using an
On/Off switch on the controller (See page 16). This feature is
only activated when the door is in the closed position, so that
electric strikes, magnetic locks or electric latch bolts are not
operated needlessly.
In addition, the ED 800 offers an
external output terminal
, rated
at
12 volts DC
, at a maximum of
500 milliamps.
This can be
used to power an electric strike or any accessory of compatible
voltage.
The ED 800 also has a
built-in safety circuit
. While not
required by the ANSI A156.19 standard, this safety circuit can
provide the ultimate in safe door operation. When the optional
presence sensor is installed, the door will not operate under
power when it detects an obstacle within the swing area of the
door. In addition, the unit will hold the door in the fully opened
position until traffic has cleared from the swing area of the door.
Under no circumstances however, shall the presence sensor
serve to stop an already moving door in the event that the swing
area of the door becomes occupied, once the door is in motion.
In this case, safety is assured by the low opening force, low
opening speed, and obstacle default function of the unit.

INSTALLATION OF UNIT
Introduction
Prior to installation of the ED800, confirm that the door is in proper working order. Hinges or pivots must be in good condition and
the door must swing freely through the entire opening range anticipated with the ED800.
All door repairs must be performed
prior to installation of the ED800.
Ball bearing hinges or needle bearing pivots are recommended for proper ED800 operation.
The ED 800 is a non-handed unit which mounts to the door and frame much the same as a standard door closer. The unit is
designed so that it can be installed by one person. The backplate is equipped with unique slots to aid in installation. Two screws
are pre-installed into the frame. The unit is then hung on the two screws until the balance of the screws can be installed and
tightened.
There are four different ways that the ED 800 can be ordered and installed:
ED 800J
- Top jamb installation where the unit is attached to the
header on the push side and the arm shoe is attached to the
door. The standard unit accommodates a reveal from 2 to 6
inches. For reveals of 0 to 4 inches, the C800R bar and shoe
must be specified. For reveals of 4 to 8 inches, the C810R bar
and shoe must be specified. For reveals of 8 to 12 inches, the
C812R bar and shoe must be specified.
ED 800J x Drop
- Top jamb installation where the unit is located
to clear a low ceiling condition on the push side of the door.
This is otherwise similar to the ED 800J.
ED 800J x Drop x 830
- Top jamb drop installation to clear a low
ceiling on the push side. The 830 is an arm shoe drop plate
designed to connect the ED 800 arm to a narrow top door rail in
this particular application. This is otherwise similar to the ED
800J x Drop.
ED 800T
- Track installation where the unit is attached to the
header on the pull side and a track arm assembly is attached to
the top of the door.
Refer to individual templates for exact dimensional requirements
for each particular application.
Please use the full size
preparation template included with the ED 800 when
preparing the door and frame.
