摘要

The safety device (2) has a fire protection device (3) and two detecting units (4,5) connected with a control unit (6) for detecting temperature in an engine compartment. The fire protection device releases an extinguishing agent in the engine compartment, when a detected temperature value is exceeded to a predetermined temperature threshold value stored in the control unit. The first detecting unit is arranged to an engine block (1.1) of a motor vehicle (1) for detecting the temperature of the engine block. An independent claim is included for a method for operating a safety device with a fire protection device.
