Compatibility and Installation Notes
The GSM Gate Opener Controller is compatible with gate motors, door locks, gate operators, barriers, and access systems that accept an external NO/NC dry contact trigger input. A working Nano SIM card with suitable mobile network coverage is required, and the relay output must be wired correctly to the gate control panel input. Professional installation is recommended because incorrect wiring, relay timing, or power supply selection can damage the controller or cause unsafe gate operation. The manufacturer also notes that the antenna must be installed before use, and setup is completed through SMS commands; review the official WH-120 technical product details before installation.
