Feature Product

The GSM Telephone Entry System uses a SIM card to program, activate and communicate with your gate. A direct phone line connection from the house is not required which means there is no possibility of signal loss due to long wire runs. This system is ideal for users going wireless and not using a home phone line. 

Access your gate system from anywhere in the world.
