| Comment: | Prerequisite for operation is a Class 1 vehicle electrical system architecture according to EN 50533. If voltage (e.g. 230 VAC) is passed through the alarm relay, the SELV signal wires lose their property of reinforced insulation, meaning they then have only basic insulation. The SELV property (reinforced insulation) is not lost when voltages of up to 110 VDC are passed through the alarm relay. |
