GF82.25-P-4100-04T Emergency Alarm System Activate Button Function
- with CODE (934) Taxi emergency alarm unit


The emergency alarm system trigger button (S62/6) is monitored by the multifunction control unit for special-purpose vehicles (MSS) (N26/9). If the emergency alarm system activate button (S62/6) is pressed, the input of the special vehicle multifunction control module (MSS) (N26/9) is short-circuited to ground to generate an emergency alarm.

For line monitoring purposes the emergency alarm system activate button (S62/6) has a resistor (sensing resistor) connected in parallel. A small test current flows through this resistor when the emergency alarm system activate button (S62/6) is at rest. When the current drops below a defined threshold this indicates an open circuit.
