Abstract

Procedure for transmitting measurement values in a fire alarm system, the measurement values being determined by several fire alarms connected in parallel to warning lines, introduced in an analog way into a central evaluating device, where they are combined to obtain differential warnings of faults and respectively alarm, characterized in that all the warnings of a line are explored in a cyclical manner, each warning being induced, after a characteristic advance time for it, to transmit a current pulse of a duration proportional to its measurement value, and because in the central evaluation device, by measuring the advance time, the direction of each of the warning devices is determined in each case, and by measuring the pulse width, its measurement value.
