。[Scope of Utility Model Registration Claim] is) an optical transmitter/receiver panel each having an optical transmitter, an optical receiver, and a report detector; a report push button; and an emergency light switch that operates when the push button is pressed and cuts off optical signals. An emergency alarm device that is equipped with a reporting device and an optical fiber cable that connects this device to a transmitter/receiver board, and detects notifications from push buttons based on the strength of the optical signal. (2) An optical branching device is installed in each emergency notification device that is connected to an optical switch and attenuates the optical signal, and the intensity of the optical signal that returns to the optical receiver of the receiver panel is used to notify which emergency notification device or block the emergency notification is. The emergency alarm device according to claim 1 of the utility model registration claim, which detects whether the device is a device or not. (3) The emergency alarm device according to claim 2 of the utility model registration claim, wherein the emergency alarm device is provided with an optical fixed attenuator that is connected in series or parallel with an optical switch and that attenuates the optical signal.
