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.
