The “GSM Switcher” is another very popular form of access control, especially on very busy multiple-use applications and is fitted to the Gate control panel. By calling the number of the SIM card inserted in “GSM Switcher”, the system checks if the number of the caller is recorded in the memory. If the number exists in the database, the system rejects the call and turns on the relay for the determined period, opening the gate without charge. If the number of the caller is not recorded (random caller or misdialed), the contacts of the relay are not connected and the gate will not open.
Up to 200 numbers can be stored & this can be managed by adding and deleting entries via text.
This is absolutely ideal for many busy sites & cuts out the cost of Remote Control Transmitters or the need to continually change a Keypad code.
