- with CODE (359) TELE AID emergency call system
In the quiescent state an electric current flows via the control resistor (parallel to switch contact) that is built into the SOS switch (S93/3s1). The
emergency call system control unit (N123/4) uses this to detect whether the feed line and the ground line are OK. When the SOS pushbutton switch
(S93/3) is pressed the control resistor is bridged by the switch contact.
The SOS switch (S93/3s1) signal is read in via a discrete line by the emergency call system control unit (N123/4). When the SOS switch (S93/3s1) is
operated the emergency call system control unit (N123/4) detects a manual emergency call and then places the call.
