Abstract

A theft protection system for an installation unit recessed in an installation passage protects the installation unit mechanically and by an electrically initiated alarm by permitting the installation to be pulled out of the installation passage to a distance limited mechanically by a movable protection stop and by actuating an electrical theft protection contact within this distance by utilizing the relative motion between the installation unit as an installation retention arrangement and the installation passage to initiate the alarm.
