Maybe not exactly a wiring regs question, but does anyone know of a fire hood for an 8 inch ceiling loudspeaker that offers 120 minute fire resistance? I can find 90 minute hoods, but this design (not ours I hasten to add) has put loudspeakers into a 120 minute fire ceiling and this is proving a bit challenging.
We can possibly change to wall loudspeakers in these areas but if we can find a 120 minute hood that would be the easiest solution.
Thanks,
Jason.
