4G Switch with RF for Remote Control (GMT-4GSRF)

The GMT-4GSRF GSM Switch with FR Key Fob incorporates a professional, industrial grade engine that receives calls at its SIM number, as any ordinary GSM mobile phone.

The system operates in the GSM module quad band 850/900/1800/1900/2100mhz frequencies.

To give an example, if your SIM has the number 07234567890, this is the number you must call to open the gate. The system has a memory where you will store the numbers of people enabled to open the gate (up to 120). When the Gate Opener receives a call, it will check the calling number is in the WHL list, *answer the call for 3 seconds*, then reject the call and open the gate if the number is recognized. *The unit answers the call which means any sim provider can be used as there are timing issues with these kind of switches and certain network providers*

The advantage of this over other systems is that you do not have to leave the car to open the gate avoiding weather conditions or safety issues.
