GSM Key to EasyGate (Model: GSM-KEY-DC) 
               
              What is GSM-KEY? 
            The GSM-KEY System is an advanced secured system that is based on the cellular   network ,
              The GSM-KEY system works with Caller ID and when an authorize number   calls, the system will recognize the caller and open the gate, 
              While it will   not answer the call as the call will not cost anything. 
              
            How does it work? 
            GSM-KEY  incorporates a professional industrial grade GSM engine that   receives calls at its SIM number, as any ordinary GSM phone. You need to use any   operator that operates in the 900/1800 Mhz band, that is the standard in most of   the world, 
              Just to give an example, if your SIM has a phone number 35674564,   that is the number you have to call to open the gate.GSM-KEY has a memory   where you will store the numbers of people enabled to open your gate (up to 200)   When GSM-KEY receives a call, it will check the calling number and if the   number is in the list you have prepared it will reject the call and open the   gate.  
              
            Does it work with any electric gate? 
            Yes. All electric gates have a   button that is used to open them. GSM-KEY has a relay whose contact has to   be connected to the oopening button. Actually it pushes the button in your   place. 
              
              Does it cost me anything to use my phone to open my gate? 
            GSM-KEY   doesn't answer the call, it simply checks the caller ID. Your network must send   the caller ID otherwise GSM-KEY won't work. Usually operators don't charge   until you answer the call, so it won't cost you anything to open the gate with   GSM-KEY. 
            Of course you need to have an active SIM inside it, and this   may have a monthly fee regardless of the calls. 
            Check your local operators   for these details. 
            
            What is the maximum working distance? 
            GSM-KEY doesn't have   limitations like a normal remote control. Using a mobile phone you can open from   very far away, even from another city! 
            It is really convenient to arrive in   front of your house when the gate is already open, without having to wait in the   middle of the road.  
            How can I enable different phone numbers to open my gate? 
            To store a   number, you simply send an SMS, that starts with a password, to GSM-KEY,   indicating the phone number to enable, and its position in the list. 
            Numbers   are stored in GSM-KEY memory and not on the SIM. This prevents somebody   from removing the SIM to copy all the numbers into a mobile phone. 
            Only the   one who knows the password can insert or delete enabled phone numbers. 
            For   faster operation you can order from us a special Software to connect   the GSM-KEY to your PC and input numbers.

            What else do I need besides GSM-KEY?

            Is it difficult to install it? 
            You need to connect the 2 wires that come   out of the box in parallel with the Gate push button. 
              Connect it to AC power   ( 230V 20VA), insert SIM and start programming numbers (12 numbers can be   programmed with only one SMS).
