Description
The WT-9003 GSM remote controller incorporates a professional industrial grade GSM engine that receives calls at its SIM number, as any other ordinary GSM phone. The system operates in the GSM module quad band 850/900/1800/1900Mhz. Just to give an example, if your SIM has a phone number 9228 9810, that is the number you have to call to switch on/ off electric devices such as Automatic Gate, Heater, Fridge, HVAC, pump, motor and a lot more.
The system has a memory where the designated numbers are stored with a maximum of up to 250 numbers. When the WT-9003 receives a call, it will check the calling number and validate it with the listed numbers. If the number is in the list then it will reject the call and open the gate, switch on the boiler, turn on the heater, power up the motor and etc. The system does not answer the call, it simply checks the caller ID. Your network must send the caller ID otherwise the WT-9003 remote control will not work.
