Power controller for a door lock and method of conserving power
A power control system for use with an electric lock mechanism having an actuator comprises a power supply to output an output voltage to the actuator. A credential device signals the power supply to output the voltage upon receiving an authorized code. A microcontroller controls the power supply, the credential device, and the actuator and may operate in an Access Mode or a Dog Mode. When in Access Mode, the actuator is unpowered and the credential device is powered until an authorized code is received and the power supply powers the actuator. The Dog Mode has an awake mode where the actuator is powered and the credential device is unpowered after the actuator remains in the powered state for a length of time. A sleep mode has the actuator unpowered and the credential device powered until an authorized code is received and the power supply powers the actuator.
1. A power control system for use with an electric lock mechanism having an electric actuator, said power control system comprising:
a) a power supply configured to receive power from a voltage source and to selectively provide an output voltage to said actuator;
b) a credential device configured to detect a credential, and wherein, upon authentication of said credential, a signal is provided to said power supply to provide said output voltage to said actuator; and
c) a microcontroller operatively connected to said power supply and said credential device,
wherein said microcontroller is configured to selectively operate in either an access mode or a dog mode, wherein said dog mode includes an awake mode;
wherein, when in the access mode, said credential device is in a powered state and said actuator is in an unpowered state,
wherein, when in said awake mode, said credential device is in an unpowered state and said actuator is kept in a powered state until said awake mode is terminated, and
wherein said credential device is placed in said unpowered state after the actuator remains in said powered state for a predetermined period of time.
