Claim Text:
1. An alarm/monitoring system interface for an object having at least a ferromagnetic component, the alarm/monitoring system interface including: (a) an interface body; (b) a first electrical contactor, the first electrical contactor including an electrically conductive ring magnet having a magnetic field associated therewith to provide a magnetic attractive force between the ferromagnetic component and a ring face of the magnet located proximate to a first face of the interface body, the first electrical contactor also being electrically connected to a first lead; (c) a second electrical contactor electrically connected to a second lead, the second electrical contactor (i) extending from the first face of the interface body at a location within an area defined by an inner surface of the magnet and (ii) including an outwardly flared part that extends to a contact point spaced apart from the ring face of the magnet in a direction away from the first face of the interface body, the contact point being located beyond a boundary defined by a cylindrical shape which extends along a central axis of the magnet and which encompasses the inner surface of the magnet; and (d) wherein the first electrical contactor and the second electrical contactor are located on the interface body so that when the interface body is placed in an operating position with respect to the ferromagnetic component, a portion of the ring face of the magnet and a portion of the second electrical contactor each contact a respective surface of the ferromagnetic component to provide a closed electrical circuit between the first lead and the second lead, the closed electrical circuit providing a monitoring input to an alarm or monitoring system.
