Emergency alarm activation switch, function - GF82.25-P-4100-04A

Model 140 except 140.063/07, 202, 210 220 

Function with taxi emergency alarm 

In the non-actuated state current flows through the "sense" resistor installed in the emergency alarm activation switch (S62/6)  . This allows the emergency call system control module (TELE AID) (A35/8)  to recognize that the feed lines and ground lines are okay.

When the emergency alarm activation switch (S62/6)  is activated the "sense" resistor is bridged by the switch contact. This is recognized by the emergency call system control module (TELE AID) (A35/8)  and a TELE AID taxi emergency alarm is triggered.
