ETM 3

The Energy Transfer Monitor Hinge (ETM) like the ETH hinge is the ideal way to pass low voltage power from the hinge jamb to the lockset. There are no exposed wires, cables or switches that can be tampered with and the hinge maintains the same appearance of a conventional non-power transfer hinge. What distinguishes it from the ETH hinge is that it has a concealed switching mechanism that monitors the position of the door.
