Abstract
A method for measuring a line resistance R() and determining control line () faults in a hazard warning and control system. The control lines () connect a control device () to an actuator () using an actuation voltage Uin the case of an event and supplies the actuator () with a monitoring voltage Uin the case of a monitoring process using a monitoring module (). Furthermore, the control device () has a constant current sink (), which can be activated by a microcontroller (), and a switchover device (). In order to determine the line resistance R(), a constant voltage supply is provided in a measurement time interval Δtby an energy store () integrated into the monitoring module () and is fed back to the control device (), and the switchover device () deactivates the monitoring voltage Usupply from the control device () to the actuator () during the entire measurement time interval Δt.
