PURPOSE: An exit guide board with a complex alarm function and a recharge battery is provided to help people to more rapidly and safely evacuate from a danger zone in an emergency situation. CONSTITUTION: The exit guide board comprises a smoke/fire detecting sensor(4), a gas detecting sensor(5), a vibration detecting sensor(6). According to the operation of these sensors, a control board(7) serves to generate an alarm such as a siren by receiving any signals for informing risk from the sensors when the leakage of gas, a fire, the breaking risk of a building, and so on are detected, to turn on a light emitting lamp(13) installed on the front surface of the exit guide board for more rapidly informing the emergency situation, to actuate other twenty exit guide boards at the same time, and to inform the emergency situation to a control office/a guardhouse.
