A power supervised emergency warning device provides a shaking motion to a piece of furniture coupled thereto upon receipt of an electronic actuating signal from an external closed contact type device. A backup battery provides power to the device in the case of a main power outage. External warning devices may be coupled to the device which are activated upon receipt by the device of the actuating signal. Additional external device hook-ups are provided as well as the ability to be coupled to auxiliary modules. The auxiliary modules accept actuating signals from additional external closed contact type devices to produce shaking. Additional indication devices may also be coupled thereto. Additional auxiliary modules may also be chained thereto.
