Abstract: A door lock engagement status indicator system comprising a position indicating sensor installed adjacent to a striker box, wherein the position indicating sensor toggles between a first state identifying when a door lock throw bolt is placed in an extended or locked position and a second state identifying when the door lock throw bolt is placed in a retracted or unlocked position. A local lock engagement status monitoring apparatus monitors the sensor and displays the status of the indicating sensor, representative of the monitored lock status. Each local monitoring apparatus communicates with a master monitoring apparatus, wherein the master monitoring apparatus displays a complete summary of all of the associated local monitoring apparatus. The displayed status can utilize green and/or red lights providing a simple and clear monitoring system.
