SDC 1581S MINI EXIT CHECK DELAYED EGRESS EMLOCK - Manual (Page 5)

STEP 1. Mount armature to door. (See figures
2A, 2B & 2C.)
STEP 2. Install the mounting plate (filler plate
and/or angle bracket if needed – see figures 1A,
1B &
1C) to header with only the two screws at
the slotted hole locations at this time. Snug the
screws down lightly (do not torque) so the
mounting plate & lock can be repositioned later.
STEP 3. Temporarily install the lock to the
mounting plate with the 1/4-20 socket head
screws encased in the lock.
STEP 4. With the lock mounted, close the door
so the armature just comes into contact with the
face of the lock. If the door is not completely
closed as the lock & armature touch, open the
door and reposition the lock away from the door
as described in step 2.
(THIS IS TO PREVENT
THE DOOR FROM USING THE LOCK AS THE
DOOR STOP.)
STEP 5. Remove the lock from the mounting
plate, mark & punch all remaining screw and
wiring holes. Drill & tap holes as indicated on the
paper template and install all screws.
STEP 6. Reinstall the lock to the mounting
plate. At this point, if there is no need to remove
the lock for painting or any other reason, install
the anti-tamper plugs over the socket head
mounting screws, using a soft hammer to avoid
damage to the lock case.
