<P>PROBLEM TO BE SOLVED: To provide a security device capable of facilitating the setting of a sensor terminal and rapidly performing communication with a main device. <P>SOLUTION: The main device 1 comprises an alarm means 1b performing the setting or release of an alarm mode; a first lighting line communication means 1a transmitting the alarm mode; and a control means 1c controlling the alarm means 1b and the first lighting line communication means 1a. A terminal device 2 includes a second lighting line communication means 2a performing data communication with the main device and a first optical communication means 2b optically communicating receiving data of the second lighting line communication means. The sensor terminal 3 includes a second optical communication means 3a performing optical communication with the first optical communication means 2b, an interface means 3b connected with a sensor means 4, and a battery power source 3c. By this, the setting of the sensor terminal 3 is facilitated, and the sensor terminal 3 can rapidly make the setting or release of alarm and the state of the sensor means 4 communicate with the main device 1 through optical communication with the terminal device 2. <P>COPYRIGHT: (C)2007,JPO&INPIT |
