Approval: EAC
Comment: A prerequisite for operation is a Class 1 vehicle electrical system architecture according to EN 50533; if supply potential (e.g. 230 VAC) is passed through the alarm relay, the SELV signal wires lose their property of reinforced insulation and 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.
