The passageway selective detector mechanism and system of this invention comprises a mat positionable within a passageway, such as a doorway, gateway, or the like. Imbedded within the mat are magnetically operable electric switches which are electrically connectable to an alarm or signal member and to a source of electrical energy. Thus, when any of the switches is operated, the alarm or signal member is energized. The mechanism and system includes magnetic elements associated with selective personnel for operation of at least one of the electric switches as the selective personnel travels over the mat. The magnetic element may comprise an inner sole within the shoe of the selective personnel to actuate an electric switch, which actuates the alarm or signal member as the selective personnel steps upon the mat. The magnetic element may also comprise a magnetic member carried by a wheelchair in which the selective personnel travels and which actuates an electric switch, which energizes an alarm or signal member as the selective personnel travels over the mat in a wheelchair.
