| Comment |
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. |
