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 detector base (3) is used for releasably receiving a hazard detector (1), for setting two operating modes of hazard detector. The electrical characteristic value of two-terminal resistor (R1) in detector base is read out by an electronic controller (4) of hazard detector. The two-terminal resistor is connected to electrical contact (XEA) that is connected to electrical contact (YEA) of electronic controller. An external optical and/or acoustic alarm generator is connected with hazard detector, for reading the electrical characteristic value of two-terminal resistor. An independent claim is included for hazard detector.
