The GSM-230-3G opens the gate when you ring it from your mobile phone. The module recognises a stored number and switches the relay; unknown numbers are ignored. The call is not answered, so control is free of charge and works with any phone without an app. Memory for 200 numbers is suitable for apartment buildings, companies, hotels or holiday resorts.
Wiring
- Connect 4 wires: two for the power supply, two for the operator's control input.
- Insert a nano SIM card (3 V) with the PIN code and voicemail disabled.
- Store numbers remotely with the #TEL SMS command.
The module fits under the operator cover and is powered from its 24 V terminals. If the operator does not have a suitable voltage, use the supplied adapter.
Other options
- SMS commands – permanent switching on and off of the relay with the ON/OFF command.
- Relay switching time – from 0.5 to 9.5 seconds.
