Door Opener/Magazine Lock Assembly

It is necessary to remove the Door Opener/Magazine Lock Assembly in order to replace the
Control Panel.
The Door Opener/Magazine Lock Assembly consists of two subassemblies that must be
replaced as a matched pair. The two pieces are mounted on opposite sides of the bulkhead that
separates the electronics compartment from the cartridge magazine. The bracket on the right
of the bulkhead supports the motor for the Door Opener/Magazine Lock. The mechanism can
be operated without power by inserting a straight-bladed screwdriver through a hole in the
bracket identified in Figure 6-9 to engage a slotted shaft about 1 1/2" below the bracket.
Removal
Refer to Figure 6-9.
