GSM intercom dialer – Door station with SIM Card. Calls direct to mobile phone. Wireless. No Cables required

The GSM VARIOBell can store up to 1000 numbers (SIM card dependent), with up to 7 numbers per user (i.e. each call button or speed dial on keypad). The GSM VARIOBell door station is used for incoming and outgoing calls, incoming calls can be accepted based on the list stored on the SIM card. Relay contacts can be controlled remotely by calling in (calling/ringing to the SIM card number of the GSM VarioBell, only  calls from listed numbers are accepted to control the relay). The relay contacts can be also controlled remotely during an active call by dialling a DTMF code or if there is no active call, by entering an access code via the keypad of the GSM VarioBell. The relay can be switched ON/OFF remotely via SMS. There is also a programmable input for SMS alerts (alarm alerts) and monitoring of sliding gate status. GSM numbers stored on SIM card can have limited access to the restricted area based on day, time, calendar period (MON-FRI only) for e.g. number of pre-determined entries.
