The disclosed herein controlling automation system destined forremote monitoring and remote warning purposes via general-use GSM cellular telephony is composed of five co-operating circuits (SX.1, SX.2, SX.3, SX.4, SX.5). The circuit SX.1 co-operates with the circuit SX.3 while the SX.2 circuit is able to cooperate with most of the commercialized alarm systems and serve as remote control and remote warning system sending automated phone calls to the operatorin case of forcing conditions. The SX.5 circuit is used for the access control in buildings/companies where access of individuals is selected; it offers the possibility of registering the time and date of use upon connection of the NOKIA device to a PC (see page 2, SX.5). The aforementioned circuits are located into airtight and humidity-resistant boxes at the bottom of which there are formed openings accomodating the entry and exit of cables with adequate glands. In dependence on the embodiments to be realized, these boxes are characterised by a control panel equipped with a cutout switch and pilot lamps indicating the operational condition of the control panel. The invention offers the following possibilities of operation and embodiment: 1) Remote control of the device from whatever point covered by the GSM cellular telephony network; 2) In contrast to conventional devices using radio frequency receptors (RF), the invention is not influenced by other emitters emitting on the same radio frequency or by other interferences. Commands by other SIM card for the control of the operation by third parties are excluded; 3) The commands addressed to the invention are not debited to the cellular telephones of the operator(s); 4) The invention recognize the operator by the no of the SIM card so that the ON-OFF function of the cellular telephone may be energized with no use of user's identification codes habitually used in conventional cellular telephones; 5) The commanding operators accepted by the invention are stored up |
