. Intended use.
The ED is a low power electromechanical operator
used exclusively for opening and closing interior or
exterior swing doors.
. Packaging
The ED operator is packaged in a header for overhead
concealed (OHC) installation.
For double swing doors, two ED operators are
packaged in a single header.
. Low energy operator.
The ED is supplied only as a low energy operator
(ANSI/BHMA A.). The operator is supplied with a
reduced power motor and a brake. The brake is used
during door hold open time.
WARNING
To reduce risk of injury to persons, use this
ED low power operator only with an
automatic door for which the ED is
designed for. Reference Chapter , Technical
Data.
