Security system monitoring method

摘要

The method involves calling a preset security monitoring telephone number of a control station via a communication network. The call is carried out in preset time intervals or to preset times. Preferably, the control station identifies the security system on the basis of the transmitted telephone number. A positive identification of a security system is stored in the security system. If the system is not identified after the time interval, alarm actions are started. A fixed network with caller telephone number transmission is used.
