The system includes a security device having a user device for imputting a first control signal to block the incoming telephone call, and for inputting a second control signal for controlling at least one feature of the security system, at least one sensor for detecting an emergency event within a protected area. The sensor generates an alarm signal. The system further includes a control section for processing the first and second control signals. The control section generates a control signal based upon the first control signal. Based upon this control signal, a line seizure means opens or closes a connection between an incoming telephone line and a telephone device. The security system has continuous access to the incoming telephone line, even though the line can be isolated from the telephone device.
