[origin: EP1439510A1] The alarm system has at least one detector (M1) for providing an alarm signal transmitted via a LV communications network (KN) to a reception station (AE). The transmission device (UE) supplying the alarm signal to the LV communications network has a current supply circuit (EV) with a transformer (TR) for delivering the supply voltage for the transmission device from the communications network voltage.
