G202 3G/4G GSM Gate Opener Relay — Wireless Door Access (Replacement for RTU5024)

The G202 3G/4G GSM relay provides wireless door and gate access control and is a direct replacement for RTU5024. Security is handled via caller-ID so calls from unknown numbers are ignored. Administrators can add or remove users using SMS text commands, eliminating the need to distribute physical remotes or keys. You can configure up to 200 authorized phone numbers at the specified time. The relay’s open or close time is programmable to fit your requirements. When the relay operates it can send an SMS confirmation to the owner or the authorized calling number — this confirmation feature is editable by the user.
