Abstract
A method and a device complementing a normally preinstalled telephone entry system with option for certain residents to open an entrance door by calling and presenting their telephone numbers/addresses. Advantageously, the telephone entry system's already existing tele connection, subscription, telephone number/address and possible answering are employed for the functioning.
Claims6
A method for use with an installed and lock-controlling telephone entry system, “tele-intercom” (3/23), said method comprising the steps of:
- intercepting the wired telecommunication line (2/22) of said tele-intercom at a suitable point between said tele-intercom and a PSTN by connecting to said point a lock (7/27) controlling device (1/21) capable of making or breaking said line's path into said tele-intercom and of reading, processing and reacting to at least one CLIP arriving on said line;
- into said device programming numerical information of said at least one CLIP and how to process and react to it after reading it;
- and
- after found correspondence between said information and said at least one CLIP reacting in one or both of initiating opening of said lock and breaking or making said line's path into said tele-intercom.
