Abstract
PURPOSE: To reduce the number of the detection switch without lowering the anti-burglar function, by providing a switch to the receiver in order to switch the state so that the alarming signal is transmitted when the electric wave signal including only the long-time band and the signal containing also the short-time band are received.
