<p>A power supply detecting device using an RF(Radio Frequency) system is provided to detect an error of reserved power supply by using a remote control. In a power supply detecting device using an RF system, a power supply(200) provides a main power(210) and a reserved power. A detector(300) detects emergency status generation by detecting a temperature and illumination. An output part(400) has more than one illuminator(410) to light an inside lamp according to a signal of the detector(300). An input part(500) blocks the main power supply. The input part(500) receives a separate remote control(510) signal to inspect supply status of a sub power(220). A lead lamp controller(100) controls operations of the power supply(200), a detector(300), an output part(400), and an input part(500). The output part(400) has a radio(420). The radio(420) outputs a radio broadcasting of a prescribed frequency through a speaker if the emergency status occurs. The lead lamp controller(100) transmits information about the emergency state to a central controller(620). The central controller(620) manages and controls entire building. And, the input part(500) transmits a rescue signal via the lead lamp controller(100) to the central controller(620) by having a rescue button(520).</p> |
