hi,we look after a couple of HMO's in witch we have fitted mains linked smoke detectors and call points a few years ago, we also have certificate of design, installation and commissioning and test the system as recommended (Category LD2 Grade D). The council now want us to complete a FSM3/ Appendix G6 of BS 5839: Part 1, as far as we can see this is for non domestic property, is there an annual certificate for LD2 Grade D systems ?
thanks Chris Davies
