Abstract
An exemplary embodiment of the invention is directed to an elevator braking system including an accelerometer for detecting acceleration of an elevator car and generating an acceleration signal. An over-acceleration detection module compares the acceleration signal to an acceleration threshold. If over-acceleration detection module detects an over-acceleration condition, a first switching device disrupts power to a solenoid in order to activate a braking assembly.
