33/3550AWDC
Instead of traditional rods, concealed vertical cables are utilized, making use of a proven technology
that enables quick installation and allows for easy maintenance. Simplified sizing, ease of adjustment
and greater door integrity make the Wood Door Concealed exit device a more secure solution, without
the complexity associated with traditional concealed systems. Another key benefit of the system is the
ability to make adjustments to the system by simply removing the scalp plate from the edge of the
door.

10 TROUBLESHOOTING
If latches do not retract when pushpad is depressed:
Remove cover plate from edge of door
Pull down on top spool input. If the top latch fails to actuate, readjust top spool (Steps 4d-1 thru 4d-4).
Pull up on bottom spool input. If the bottom latch fails to actuate, readjust bottom latch clearance (Steps 8b-1 thru 8b-4).
If both actuate and the door is not functioning, proceed to next check.
Remove center case cover
Check lift finger screws to ensure they are still fully seated. If unseated, loosen
locking screw, and while applying pressure to the head of the lift finger screw to
seat it, tighten locking screw. If door is not functioning, proceed to next step.
With both lift finger screws fully seated, loosen top and bottom locking
screws, turn lift finger screws clockwise to end of travel, and repeat
device adjustment, Step 6.
If bottom spool input does not move during Steps 6b-2 / b-3:
Loosen bottom spool screw 10 turns.
If the 33/3550AWDC center case cover is difficult to install:
Loosen bottom screw installed in Step 5c and lift rod connector sleeve until it will go no higher, then retighten screw.
