Are smoke/heat/CO detectors connected to the electrical installation in domestic premises a “safety service” as defined in Part 2?
443.4.1 insists that overvoltage protection is provided for “safety services” as defined in Part 2, so we have no need to look to any other publication. I hold with JP, and whether intended or not, there is no doubt, having read the definition, that domestic alarms as I described above constitute a “safety system” and therefore over voltage protection is required.
