Abstract
A method of operating a safety net system of an elevator system is provided. The method includes installing a sensor in an elevator pit of the elevator system and executing a learning phase of the sensor to verify successful installation of the sensor. The executing of the learning phase includes causing the sensor to sense physical characteristics of a portion of the elevator pit when the elevator pit is known to have certain physical characteristics to generate a background reading, comparing the background reading against a reading associated with known physical characteristics of the portion of the elevator pit and verifying the successful installation of the sensor based on results of the comparing.
