Modular GSM Door Intercom - GSM VarioBell

The Alphatech GSM VarioBell doorphone intercom is a hands-free GSM phone with pre-programmed phone numbers. Phone numbers can be dialled by pressing the call buttons or the keypad. The GSM VarioBell door entry is used for incomming and outgoing calls, incomming calls can be accepted based on the white list stored on the SIM card. Relay switching contacts can be controlled remotely by ringing (GSM key function, i.e. ringing/calling to the SIM card number of the GSM VarioBell door entry phone, only calls from white listed numbers are accepted). if required, incomming calls can be accepted from any GSM number as well. The relay contacts can be controlled remotely during an active call by dialing a DTMF code or if there is no active call, by entering an access code via the keypad of the GSM VarioBell doorphone. The relay can be switched ON/OFF remotely by SMS text message. There is also one programmable input for text message alerting (alarm alerts) and monitoring of sliding gate status.
