Abstract

An access control device (10) for a manhole cover having a lid (12) and a frame (14) adapted to accommodate the lid (12) is attachable to at least one of the lid (12) and the frame (14) in the area covered by the lid (12) and has an antenna (16) adapted to receive external signals, and a connection to a remote security control unit. In a method of using an access control device in accordance with any of the preceding claims, a sender, such as a transponder, is used to emit signals received by the antenna. A method of using a security system having at least one such access control device and at least one remote security control unit. A lid or a frame of a manhole cover has at least one access control device. A method of providing a manhole cover having a lid and a frame adapted to accommodate the lid with an access control device has the following steps: preparing an access control device having an antenna adapted to receive external signals, attaching the access control device to at least one of the lid and the frame in an area covered by the lid, positioning the antenna proximate to the lid, and connecting the access control device to a remote security control unit.
