Emergency Contact Button: Description and Operation
GF82.95-P-4101-04A TELE AID Pushbutton, Function
- with CODE (347) TELE AID emergency call system (D2B)
An electric current flows in park position through the control resistor that is installed in the SOS pushbutton switch (S93/3) (parallel to the switch
contact). This indicates to the D2B telephone and TELE AID transmitter/receiver (A35/17) 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. This is detected by the CTEL and TELE AID
transmitter/receiver, D2B (A35/17) and a TELE AID emergency call is then activated.
