Abstract
An elevator door lock assembly () includes a sensor device () for providing an indication of a properly locked door. A plurality of proximity sensor elements () interact with activating elements () when the door lock assembly () is properly locked. In disclosed examples, a specific geometric pattern of the sensor elements () and the activating elements () provides redundancy and tampering protection. In a disclosed example, an output from the sensor device () provides an indication of a condition of the door lock and a building level location of a plurality of sensor devices.
