Redundant Mechanical Locks
In order to use a Redundant Mechanical lock, a method of retracting the bolt is required. An entire range of LA
GARD dials is available for alternate dial options.
1.
Locate, drill, and tap holes to mount the Lock Assembly to the inside of the safe door using the installation
template provided.
2. Locate and drill the two holes for the dial ring to be mounted.
3. Attach the lock assembly to the door using the three US 1/4"-20 (Metric M6X1) mounting screws provided.
Tighten the mounting screws to a torque setting of 30 in./lbs. (3.4 N•m).
Ensure the lock assembly spindle hole is properly
Note:
aligned with the spindle through hole in the safe door.
4. Measure total mounting thickness (door thickness +
mounting plate). (Figure 8)
5. Cut the spindle to a length of 1.125" (28.6mm) plus the
total mounting thickness.
6. Mount the dial ring centered on the through hole, and
attach to the safe door using the two mounting screws
supplied with the dial assembly. The opening index
reference mark must be in the twelve o'clock position
(Figure 9).
7. Place the dial bearing onto the dial ring.
WARNING:
The lock bolt MUST remain in the retracted
position throughout the installation procedure. To
ensure this keep one finger over the bolt while installing
the dial spindle into the lock cam.
WARNING:
Ensure that you are properly grounded to
protect the system card from Electrostatic Discharge
(ESD) damage before proceeding with the next steps.
8. Remove the two cover screws from the back cover of
the lock assembly, and remove the lock back cover
(Figure 10).
9. Carefully unplug the solenoid connector from the
system card. (If applicable, unplug the bolt switch
connector from the system card.) (Figure 10)
