Claims

[Scope of Claim for Utility Model Registration] A home security system having the following configuration. (a) A home security system includes multiple sensors, a terminal, and a security body. (b) Multiple sensors are connected to a terminal. (c) The terminal and the security body are separate bodies connected by a signal cord. (d) The signal cord connecting the terminal and the security body is also used as a power transmission line that supplies power from the security body to the terminal, and the terminal is supplied with power from the security body. (e) The terminal is a parallel terminal that converts input signals from multiple sensors into time-divided signals.
It is equipped with a serial conversion circuit, and the signals input from the sensor are time-divided and transmitted to the security body using a signal code. (f) The security body of the terminal is equipped with display means for displaying signals transmitted in a time-divided manner from the signal code, and alarm means.
