FAILSAFE EXTRA NARROW CONCEALED MORTISE BOLT LOCK
OVERHEAD INSTALLATION HORIZONTAL
1. Examine the top rail of the door for the most suitable location for the strike plate. Mark the door for the end of the strike closest to
the lock stile, and make a corresponding mark on the header to line up with the first mark.
2. Locate center line of door thickness on the header and attach adhesive cut out template to header. Lining it up with marks, center
punch the tab-mounting screw locations and counter-sink for #10 screw. Saw or rout out the cutout area. Continue to step 5.
SIDEJAMB INSTALLATION VERTICAL
3. Examine the lock stile jamb for the point nearest the center of the door height, with space available for the lock and strike. Mark
the door stile horizontal for the top end of the strike plate and make a corresponding mark on the jamb.
4. Locate center line of door thickness on the jamb and attach adhesive cutout template to jamb, lining up the the top of the cutout
with the horizontal mark on the jamb. Center punch the tab mounting screw locations and counter sink for #10 screw. Saw or rout
the frame cutout.
5. Attach the mounting tabs inside.
6. Attach power supply and access control leads to lock leads as shown on page 2. Handle the lock carefully; do not hang it by the
wire leads. Insert wiring into the header cavity carefully so they do not interfere with proper locating of the lock in the cutout.
7. Insert lock. When installed overhead horizontally, the bolt end is nearest the lock stile. When installed vertically on the sidejamb,
the bolt must be at the top end of the cutout. Secure with # 10-32 machine screw.
8. Using strike plate as a template, mark screw hole location and drill holes for screws supplied. Mortise as required. Attach strike.
9. The automatic relock switch is set for 1/8" clearance between the top of the door and transom bar or head jamb. Any additional
gap may be compensated for by loosening the lock nut and turning the switch assembly clockwise until proper adjustment is
reached. Be sure to tighten lock nut when adjustment is satisfactory.
Loosen nut.
Turn assembly
clockwise for wide
door gap.
Tighten nut.
Easy Installation or Servicing
All Space Saver locks are
easily installed in any existing
entrance merely by mortising
out a cutout, attaching the
wiring, inserting the lock, and
bolting it into position with two
attaching tabs. Cutting studs is
no longer a problem or
expense.
