No 1 for Door Entry
Telguard gained the British Approvals Board for Telecommunications in June 1994 which meant that we could plug the TelGuard system into BT phone sockets. They have systems designed for use on single houses or estates of high rise apartments.
TelGuard simply plugs in to a dedicated ‘BT’ type telephone socket, just like your home telephone. Think of Telguard as a computerised telephone. Now due to technical advances we use mobile phone technology as an alternative to a telephone land line. All that is required is a GSM SIM card rather than a ‘BT’ type phone socket. Telguard then makes calls via the mobile phone network to the destination.
There is a large memory inside the Telguard and your telephone number is programmed into the memory remotely by computer. The number is then allocated a speed dial number which is the number of the flat or house that you live in.
When a visitor arrives they press your known number (number 26 for flat 26) and then press the ‘CALL’ button. A local phone call is made, your home phone rings and when you answer the call you can speak to your visitor. Alternatively the call can be made to your mobile phone.
When you want to let them in just press the chosen digit on your phone keypad (normally the ‘#’ key) and the door opens. If you don’t want to let your visitor in simply put the phone down. If you are out the Telguard can divert the call to a mobile or your work phone so that you are still able to communicate with your visitor and let them in if you wish; it could be an important delivery. If you are on the phone there is no need to miss your visitor.
Call Waiting or Caller Line Identification from BT will let you know when another caller is trying to contact you, and who, and you can switch between calls to speak to your visitor and let them in if required. Alternatively the call can be diverted to your mobile phone which will also show the identity of the caller (ie ‘Front Door’).
