1. Part identification.
There is one component that creates the “panic release”feature on the interior of the Trilennium™ mortise lock. The long drive arm is for the interior, the short drive arm for the exterior.
2. Remove plastic covers
A. The black plastic “rehanding covers” are removable. Depress the snap lock using a fingernail and lift the cover out.
B. One edge is under the “I” beam, so twist it to the side slightly.
3. Reverse arms.
Once you have removed both plastic covers, reverse the drive arms. See reference chart for correct placement. Reinstall the covers.

All Trilennium ® locks include a “panic release” feature for the interior lever. Operation of the lever disengages the deadbolts and latches simultaneously. Trilennium locks with the panic release feature comply egress door requirements described within International Building and Residential Codes. State or municipality codes may differ from these.
Tools required
• #2 Phillips Screwdriver
• Deadbolt Actuator
• Lock Actuator wrench
Parts required
• Exterior Link Arm Kit TC-EXTARMKIT
NOTE:
The removal of the “panic release” feature from your door system may prevent it from meeting egress door codes in your area. By removing the “panic release” feature the homeowner is taking responsibility for changing this part and must be made aware that it may create a code violation.
1. Part Identification
The panic release feature is created by use of a long drive arm. To eliminate the panic release this long drive arm is replaced with a short drive arm.

• Carefully remove the snap ring (U-shaped locking pin) with a flat head screwdriver.
• Lift the spring retaining plate out of place
(Careful, spring may jump out of place).
For the Circular tabbed snap ring:
• Open the ring using the Snap Ring Pliers.
