Remote Control Unit (JB2403G)

The JB2403G Remote Control Unit has been specifically designed and  configured to incorporate a professional industrial grade GSM Engine that receives calls at its SIM number, as any ordinary GSM phone. 





The JB2403G operates in the GSM module Quad-band 850/900/1800/1900Mhz. Just to give an example, if your SIM has a phone number 5638 9110255, that is  the number you have to call to activate the switch. 

The JB 2403G has a memory where you will store the numbers of people enabled to activate the switch(s) (up to 50). When the Remote Control Unit 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 activate the switch. 



An example of this over other systems are that you do not have to leave the car to open your gates, or to arm/disarm an alarm system or simply reset a device, avoiding weather or safety issues, you don't need to carry around a separate remote device or indeed replace it, if it were to get lost! 


Simply dial the simcard number to control the unit whether it is to activate a switch or to open the gate/garage door. It will reject your call so you are not charged.

Phone list for added security up to 80 stored numbers.
