Introduction
Call ‘2’ open (C2O) is a self contained access Control Solution which provides relay changover
contact output which can be used to operate gates / barriers etc.
When C2O receives a telephone call, if ‘White Mode’ is enabled It checks the caller’s tele-
phone number with its own ‘White List’ and if valid, C2O operates its relay output momentari-
ly.
Because C2O rejects the call there are no call charges incurred. (Using current call charging
structures).
The user can set upto 100 numbers on the white list, or set the C2O ‘Open’ to any caller
Typical Application Connection:
Normally the C2O output relay is wired across the switch which operates the Gate.
In order to connect the C2O across a standard push switch the relay COM and NO contacts
are wired in parallel to the users gate wall push switch.
Hardware Features
SIM card
The unit will accept SIM cards of most types subject to the following restrictions.
The SIM card should be inserted into C2O before applying power
Only 3 Volt SIM cards should be used.
The message memory of the SIM card should be clear before it is fitted to the C2O unit.
SIM cards that have been protected by means of a PIN (in a mobile phone) will not operate in
the unit.
Some types of pay-as-you-go SIM cards may require regular call activity (once every 3 - 6
months) to remain registered.
