Installation and Cables for an Add-on Interface Module

An add-on interface module would be located on the underside of your extension, in the rectangular opening on the underside of your extension, designed for this purpose.

It is connected to your extension with a connector that features a rigid extender attached with three torx-type screws that require an adapted screwdriver.

External ring devices (both audible and visual) are directly connected to the module using an RJ12 connector.
