During a fire the ceiling cavity can allow fire or smoke to
spread throughout a building. To inhibit fire entering the
cavity via the ceiling loudspeaker it can be fitted with an
LBC 3080/01 steel fire dome. This is mounted on the
loudspeaker assembly using four self-tapping screws
supplied with the fire dome. The fire-dome has knockout
holes for two grommets (supplied) and two cable glands.
This fire dome can only be used with the ceiling speakers:
LBC 3087/41 LBC 3090/01 LBC 3090/31 LHM 0606/00
and LHM 0606/10.
