3G – Compact GSM/3G mobile relay access technology for gates, barriers and remote equipment
G-202 3G GSM Gate Opener is a cellular remote-control relay designed for access control and remote switching applications. It allows authorised mobile-phone users to trigger an automatic gate, barrier, garage door, shutter or other compatible equipment by making a call or using supported SMS commands.
The G-202 uses caller-ID authorisation so unknown callers can be ignored while programmed users are allowed to activate the relay. It supports up to 200 authorised numbers in commonly documented versions and is suitable for villas, offices, warehouses, parking entrances and other properties where convenient phone-based gate access is required.

Frequently Asked Questions About 3G GSM Gate Opener
How many users can be added to the G-202?
Commonly documented G202 versions support up to 200 authorised phone numbers.
Can the G-202 3G GSM open a gate with a free call?
The controller is designed to recognise the caller ID of an authorised number, reject or avoid completing the normal voice call and activate its relay. Mobile-plan behaviour should still be confirmed with the SIM provider.
Can it be used with a parking barrier?
Yes, when the barrier control board has a compatible relay-trigger input. The correct terminals and relay logic should be confirmed before connection.
Does the G-202 3G support 4G?
G202 products exist in different cellular versions. The specifications associated with this record are primarily GSM/3G, so the exact supplied unit should be checked rather than assuming 4G capability.
Can I add or delete users without visiting the gate?
Supported versions allow authorised-user management through SMS commands, provided the controller has active network service and the administrator settings are configured correctly.
