Position hub toggles

 (if necessary)

1  Check whether the hub toggles are in the proper position 

for the lock. See the table below and Figure 9.

Note 1: 

For LH & LHRB doors, the inside is the back side of the 

case and the outside is the cover side of the case. 
For RH & RHRB doors, the inside is the cover side of the case 
and the outside is the back side of the case. The cover is 
mounted to the case with four screws.

Note 2: 

If the lock has an optional RQE status sensor, two RQE 

status switches are installed in the mortise case. However, 
only the switch for the inside of the lock needs to be 
connected. Before you install the mortise case in the door, 
determine whether you need to connect the ‘Case Side’ pair of 
RQE wires or the ‘Cover Side’ pair of RQE wires, based on the 
handing of the door.

2  To change the position of a hub toggle, remove the toggle 

screw, move the toggle into the desired position, and re-
tighten the screw.

Install mortise case

1  Remove the faceplate from the mortise case, if necessary.
2  Insert the mortise case into the mortise cavity, while 

feeding the sensor and solenoid wires into the mortise 
cavity and out the sensor & solenoid wire hole to the inside 
of the door.

Note 1: 

The armored front of the mortise case self-adjusts to 

the door bevel.

Note 2: 

The field wire harness should be routed above and 

behind the mortise case (depending on where the hole 
through the door meets the mortise cavity).

3  Make sure there are 3

″

 to 4

″

 of slack in the field wire 

harness to allow access to the control electronics circuit 
board in the inside trim.

3  Secure the mortise case with the case mounting screws.
