Perform the Cylinder Lock/Cover Hole Plug
Installation
NOTE 1: The GL1 provides for the additional function of an optional key-
operated cylinder lock. The cylinder lock can be installed to
either side of the lock cover, because the GL-1 lock latching
mechanism features an actuator lever that will engage the
cylinder lock from either side.
NOTE 2: IF the cylinder lock is not used, THEN a cover hole plug
(provided) must be installed on both sides of the cover.
1. SELECT the side of the lock cover that will be the most convenient
for the key access after installation if installing the optional manual
override.
2. INSTALL the optional cylinder lock.
NOTE:
The following step is critical to the proper operation of the
mechanical override. The cam of the cylinder (“MS” type)
must come into contact with the actuator lever pin to
operate the release trigger of the lock mechanism when
the cover is assembled to the lock chassis.
a. ASSEMBLE the cam, as necessary, so that the key rotation
moves the cam to point toward the rear (opening) of the cover.
b. INSERT the cylinder lock with applicable spacer (i.e., Sargent
Number 90) into the applicable cover hole (see table below and
Figure 5, “Cylinder Lock Installation”).
