Abstract
An electronic circuit to capture legacy lock controller pulses and reduce the energy consumed. The legacy pulse is captured, converted to power to power the circuit and the direction of the pulse—polarity—is determined. A substitute pulse is created at lower power and sent to a motor actuator in the lock. The total power consumed is substantially reduced by reducing the duration and voltage of the pulse. In the preferred design, the circuit also detects control voltages for solenoid locks and produces suitable control signals for a motor actuator.
