GF82.95-P-4107-04QM SOS Switch, Function
- with CODE (359) TELE AID emergency call system

In the idle position, an electric current flows over the control resistor (parallel to the switch contact) installed in the SOS pushbutton switch (S93/3). This indicates to the emergency call system control unit (N123/4) that the feed line and the ground line are OK. When pressing the SOS pushbutton switch (S93/3), the control resistor is bridged by a switch contact.

The SOS pushbutton switch (S93/3) is read in via a discrete line from the emergency call system control unit (N123/4). By pressing the SOS pushbutton switch (S93/3) a manual emergency call is recognized by the emergency call system control unit (N123/4) and is then made.
