6.4. GAP ADJUSTMENT MODE – iMXDa (Only)
As previously mentioned, the iMXDa may be “trained” to trigger at any desired gap distance
between 1/8” and 1”. To access the gap adjustment mode, ensure that the door is at rest in the
closed position. Insert the key into the IRB cylinder and rotate clockwise to actuate the mode
selection switch. The switch must be actuated three (3) consecutive times within a five (5)
second period.
 The first switch actuation will cause both LEDs to go off.
 The second switch actuation will cause the red LED to blink on and off once.
 After the third switch actuation, the green and red LEDs will alternate on and off for one
(1) second, and then the red LED will remain on.
At this point the iMXDa unit has read and stored the closed position of the door. Open the door
to the desired (gap) distance, and then turn the key clockwise once. The red LED will go out
and the green LED will go on. The door movement (gap) distance is now set. Close the door
and the unit is adjusted and ready for operation.
TO RETURN THE UNIT TO THE STANDARD OPERATING MODE WITH NO DESIRE TO
CHANGE DURING GAP ADJUSTMENT MODE, WAIT 10 SECONDS AND THE UNIT WILL
AUTOMATICALLY RETURN TO STANDARD OPERATIONAL MODE
EXD-1L Label Installation Procedure
Each iMXDa and iEXDa comes with an EXD-1L exit delay door label as required by fire code.
Please follow the included application instructions to apply the lettering to a door.
7. SPECIALIZED MOUNTING BRACKETS

8. MAGNALOCK MAINTENANCE
Visual Inspection
 Check the rubber washers for elasticity and proper pivoting. Tighten as required.
 Check for build-up of debris on the magnet face and strike armature. Clean as required.
 Check for rust on the magnet and strike plate armature. Clean as required.
 Check for iron debris on the actuator and strike (DPS) magnetic housings. Remove debris
as required.
Cleaning Methods
 Apply rubbing alcohol onto a clean cloth and thoroughly wipe down the Magnalock and
strike plate armature.
 Cleaning once a year is recommended.
 Clean every six months where minor rusting occurs.
 Clean every three months if rust conditions are severe.
