Call-To-Open (C2O)

The Call-2-Open (C2O) receiver is a self contained GSM/GPRS cellular access controller which provides relay contact outputs which can be used to operate gates, doors, booms / barriers, garage doors etc.

When C2O receives a telephone call, if White Mode is enabled, it checks the caller’s telephone number with its own White List and if valid, C2O operates its relay momentarily. The user can allocate up to 100 numbers to the white list, or set the C2O to ‘Open’ to any caller.

The C2O requires a SIM card from your cellular provider. The most economical service provider package offered is all that is required, and airtime call charges will not be incurred since the C2O never actually answers the call – it only identifies the incoming call.
