During a fire, the ceiling cavity in which loudspeakers are installed can allow flames to spread throughout a building. To prevent fire entering the cavity via the loudspeaker, the ceiling loudspeaker can be fitted with a steel fire dome (LBC 3081/02). This optional fire dome is clicked into the mounting-ring via three leaf springs, before the loudspeaker is inserted. For extra convenience, a safety cord from the fire dome allows the installer to temporarily hang the loudspeaker unit during installation. This cord also provides reassurance after installation. The fire-dome has knockout holes for two grommets (supplied) and two cable glands (PG 13).

This fire dome can only be used with the LBC 3086/41 Ceiling Loudspeaker.
