Basic Insulation of the Alarm Relay

NOTE: Take the corresponding precautions for industrial applications (EN 61800-5-1), as the alarm relay has only basic insulation (for TN/TT systems) or functional insulation (for phase-conductor-grounded networks) with respect to the supply voltage, and does not have double insulation like the rest of the interface.

The voltage switched by the alarm relay (for example 230 Vac) must then have no electrical connection to the control input and GND (electrically isolated interface).
