THE MODULE HOUSING ASSEMBLY
The module housing assembly mounts onto the control board in the lower cover. The
underside of the housing has a transparent window that is aligned with the infra red power
electronics on the control board. This provides power to the module when it is inserted into
the housing; hence the housing contains no electronics. The module housing assembly
provides a means of latching in place modules that have been inserted. The module can be
released by pressing the button on the front (or if solenoid locked by pressing a designated
key on the keyboard to activate the solenoid to release the module).
