Setting the operating mode of a hazard warning system by means of an electrically readable bipole, in particular a resistor, which is arranged in a hazard warning system socket

摘要

A bipole is fitted in a warning system socket for removably receiving a hazard warning system in order to set one of at least two operating modes of the hazard warning system. An electric characteristic of the bipole can be read out electrically by an electronic control of the hazard warning system via two electric contact pairs which are in contact with each other in the received state of the hazard warning system. In particular, the bipole is used via at least one pair of electric contacts, the pair being generally provided for externally connecting an optical and/or acoustic alarm emitter, in order to read in the electric characteristic of the bipole. The bipole is preferably a passive electric resistor.
