Abstract

A peripheral load driver that utilizes the power, wiring, and primary load of a conventional doorbell system to drive a doorbell system peripheral load at a higher current without risk of inadvertently energizing the primary load of the conventional doorbell system. The peripheral load driver comprising a power converting means for converting power extracted from the conventional doorbell system from a higher-voltage-at-a-lower-current to a lower-voltage-at-a-higher current wherein the higher-voltage-at-a-lower-current is insufficient to energize the primary load of the conventional doorbell system and the lower-voltage-at-a-higher-current is compatible with the doorbell system peripheral load.

Claims

1. A primary load bypass apparatus that when coupled to or in place of the primary load of a conventional doorbell system comprising a transformer, a primary load, and a primary load switching means for switching power to and from said primary load, can drive a doorbell system peripheral load at a higher current, said primary load bypass apparatus comprising:

a. power diverting means for diverting power extracted from said conventional doorbell system from said transformer toward said peripheral load through an alternate electrical circuit which bypasses said primary load.

2. The primary load bypass apparatus of claim 1, wherein said power diverting means comprises a current regulated circuit wherein said current regulated circuit passes current through it up to a threshold level and impedes current through it above said threshold level.

3. The primary load bypass apparatus of claim 1, wherein said power diverting means comprises switching means for switching power away from said primary load toward said peripheral load when said primary load switching means has not switched power to said primary load.

4. The primary load bypass apparatus of claim 3, wherein said switching means comprises a relay.

5. The primary load bypass apparatus of claim 1, wherein said power diverting means comprises a low impedance conductor.

6. The primary load bypass apparatus of claim 1, wherein said power diverting means comprises a fuse.

7. The primary load bypass apparatus of claim 6, wherein said fuse is resettable.

8. The primary load bypass apparatus of claim 7, wherein said fuse is a positive temperature coefficient (PTC) resettable fuse.

9. The primary load bypass apparatus of claim 1, further comprising a radio frequency transmitter for communicating with a remote radio frequency receiver.

10. A method for driving a doorbell system peripheral load at a higher current wherein said method utilizes a conventional doorbell system comprising a transformer, a primary load, and a primary load switching means for switching power to and from said primary load, said method comprising:

a. diverting power extracted from said conventional doorbell system from said transformer toward said peripheral load through an alternate electrical circuit which bypasses said primary load;

b. coupling the power diverted through said alternate electrical circuit to said peripheral load.
