Abstract
An alarm device with cross-bar that includes a telescoping cross-bar having a spring tensioning mechanism; an alarming circuit having a pair of contact points extending out from a contact point end of the cross bar; and a contact bracket, sized to detachably hold the contact point end of the cross-bar, having a moveable contact plate constructed from an electrically conductive material provided thereon in a manner such that both of the contact points of the alarm circuit contact the moveable contact plate when the contact end of the cross-bar is held by the contact bracket. The moveable contact plate is preferably pivotally supported from a central point. In a preferred embodiment the alarm circuit of the alarm device further includes a key-strip upon which a preselected deactivation code must be entered to turn off the alarm device after activation of the audible alarm.
