Abstract
The invention discloses a security system, which comprises a sensor, a terminal resistor and a host module. The sensor has a first state and a second state. The terminal resistor is connected with the sensor to generate terminal resistance. The host module is used for setting preset resistance and outputting a voltage signal corresponding to the preset resistance to enable the terminal resistor to generate the terminal resistance according to the voltage signal. The host module detects the terminal resistance. When the sensor is in the second state, the host module does not generate an alarm signal; and when the sensor is in the first state and the terminal resistance is not equal to the preset resistance, the host module generates the alarm signal. The security system can effectively solve the problem that the security system cannot work normally because the circuit of the security system is destroyed. Moreover, the host module of the security system can be used for setting loop failure time. When the time exceeds the loop failure time and alarms are not given out, a security guard company can be informed to dispatch personnel to inspect the security system.
