Abstract (en)
[origin: EP1816619A1] The device has two separate primary control lines (2, 3) that exist between two control groups of a fire alarming and control center (1) and two control circles. The control lines lead to connecting terminals, where a control module is arranged at the connecting terminals. Low-side switches (9, 10) are arranged in the control circles, and decoupling diodes (11, 18) are switched in a row in the control circles. Darlington transistors (4, 5) are arranged between the control circles, and a coil (16) of a control and/or magnetic valve (17) is switched between the control circles.
