Safety service

Are smoke/heat/CO detectors connected to the electrical installation in domestic premises a “safety service” as defined in Part 2?

  • I think I agree with Andy ... Isn't the interpretation of this partly within BS 5839-6, and the Grade of the system? Clause 110.1.3 and indent (v) to that regulation, effectively says that BS 7671 isn't stand-alone for fire detection and fire alarm systems, and that BS 5839 supplements BS 7671 in this respect.

    It's what differentiates a Grade D1 and D2 (and, if considering the interlink cable, F1 and F2) systems from Grades A and C systems?

    Clause 16.4 a) of BS EN 5839-6 appears to indicate that normal domestic mains cable is OK. Compare with the requirements for cable types for Grades A and C systems in Clauses 16.2 and 16.3 ?
