REFER TO THE PROPER TEMPLATE ACCORDING TO THE TYPE OF DOOR AND FRAME APPLICATION.
READ THESE INSTRUCTIONS AND STUDY THE TEMPLATE THOROUGHLY BEFORE BEGINNING THE INSTALLATION.
IMPORTANT NOTES:
Although electromagnetic shear locks provide the utmost in aesthetics for fail-safe applications, they are less forgiving than
electric bolt locks and direct pull magnetic locks where alignment problems exist. Therefore, great care must be taken
during preparation and installation of the frame, door hardware and the shear Emlock to attain proper alignment and ensure
positive lock
operation.
Unbalanced air conditioning (stack pressure) can hinder door alignment and must be corrected to help ensure positive
locking.
HI-SHEAR EMLOCKS REQUIRE A REGULATED 12 OR 24VDC AT THE LOCK
Use only the highest quality door closer.
POSITIVE CENTERING DOOR CLOSERS ONLY should be used on double acting doors to help attain consistent dead
center alignment.
Door latching problems must be corrected prior to installation.
INSTALLATION:
1. Make sure the clearance between the door top rail and frame header is 1/8”. Make adjustments to the door as required.
2. Adjust single acting door and door closer to ensure the door settles immediately and is fully closed and at rest against the
stop allowing for mutes, smoke seals or weather stripping where applicable.
Adjust double acting door and POSITIVE CENTERING DOOR CLOSER to ensure the door settles immediately and is
fully closed and at rest in the dead center of the frame.
3. Locate the vertical centerline of the Emlock and armature as close as possible to the leading door edge.
CAUTION: Wood door applications require the armature back box to be located an ample distance from the
door edge vertical grains, to avoid splitting from wood screws.
4. Determine the horizontal centerline of the door top rail thickness. The armature centerline will be the same.
Mark the door per the template.
5. Before determining the frame header centerline, single acting doors must be fully closed and at rest against the stop
allowing for mutes, smoke seals or weather stripping where applicable. Double acting doors must be fully closed and at
rest in the dead center of the frame.
6. Mark the frame header per the template.
7. Prepare the door and frame per the template.
