SECURITY DEVICE

PURPOSE:To secure safety and to prevent a secondary accident from occurring by appealing a message to instruct of and guide in appropriate action corresponding to the scale of earthquake and the accident status of fire, etc., from both viewpoints of visual sense and hearing sensation. CONSTITUTION:When the earthquake occurs, a detection signal from an earthquake detection sensor 15 is inputted to the CPU 3 of a device main body 1, and also, the detection signals of a fire detection sensor 17 and a gas leakage detection sensor 18 are inputted to the CPU 3. The CPU 3 is operated based on the accident status by each of the detection signals, and the CPU selects a message content with priority set in advance fitting in the status of an accident and outputs it to every part. Earthquake intensity and the message content in accordance with the earthquake intensity are displayed on the LCD screen of a screen display part 4 by receiving the output of the CPU 3, and also, the message content is notified in voice from a voice output part 5.
