| GSM-Key is our newest controller, allowing for remote control of power supply to electrical equipment. It was design especially for use for remote opening of gates and entrances. Using a cell phone the user can switch on or off up to for electrical devices. The controller is also equipped with two discrete inputs, which can be configured so that GSM-Key will send out special SMS messages when one of these inputs becomes active.  Controller usage is very simple – in the basic mode, it is just necessary to insert a SIM card containing a list of phone numbers authorized to control the relay outputs. If one wants to use the more advanced functions of the controller, it is necessary to use the configuration program, supplied with the device. GSM-Key is also capable of sending out notifications in case of power failure - to carry out such functionality, the device includes a built-in battery. |
