Protection class assignment I; If a protective earth is connected by the customer|This component for installation may have several local protection classes. This information relates to this component’s basic design.|The final protection class is based on the component’s intended installation and connection.
Conformity with standards EN 15085-1, CPC3; EN 45545-2, HL3; EN 50155; EN 61373, Cat. 1B
Approval EAC
Comment 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.
