The spec given on the plans for a relatively large dwelling was Grade A Category LD2. The house has a small basement garage, a ground floor of 250m2 and a slightly smaller first floor at 200m2. The electrical contractor fitted a standard Grade D Category LD2 system as the electrical layout was agreed on site with the home owner without reference to the architects plans. Any way, BC will not sign off as they insist that the Grade of system is changed to A. That system requires standard fire resisting cables. Of course the house is finished and decorated with no way of introducing new cabling. Could do wireless but I am not a fan (yet). The homeowner and contractor have asked me to assist. I presented a compromise where detector heads would be changed to allow panel to be fitted. Fire resistant cabling to a sounder on each floor via a service duct.
There is no special risk here but BC adamant that fire resistant cable is employed. I feel this to be unreasonable. Would appreciate your comments.
