Abstract
A power control circuit assembly for an electric door latch mechanism comprises a load control circuit module configured to distribute a DC operating voltage to power an electromechanical door latch mechanism and its associated access control device. An energy storage device such as a rechargeable battery is coupled to the load control circuit module and is configured to deliver a DC voltage to the load control circuit module wherein the DC energy storage device voltage supplies the DC operating voltage. A rectifier is configured to receive an input AC voltage and convert the input AC voltage to an input DC voltage. The input DC voltage is adapted to deliver an energy storage device recharge voltage. An energy storage device voltage detection module is configured to interrogate a DC voltage supplied by the energy storage device.
