Which fire dome or back box fits my ceiling loudspeaker?
- LBC3080/01: steel fire dome, flame red RAL 3000, EN54-24 certified, for LBC3090/01, LBC3090/31, LHM0606/10, LHM0606/00, LHM0626/00 and LBC3087/41. A white version, LBC3080/11, is available (ask us).
- LBC3081/02: steel fire dome, flame red, for LBC3086/41. With it, the LBC3086/41 is EN54-24 certified.
- LC3-CBB: ABS back box for the LC3 range. The LC3-UC06E is EN54-24 only with it.
- LC1-MFDS metal fire dome, LC1-CMR mounting ring with LC1-CBB back box, or LC1-MMSB bracket: housings for the LC1 range.
The LC3-UM06E and the new Mid and Performance Level models have a metal fire dome built in.
What cut-out does the ceiling loudspeaker need?
The new series is standardized on 180 mm: every Entry and Mid Level model and the 4-inch LCP-20MWE. The 6.5-inch LCP-30MWE needs 272 mm.
Replacing older loudspeakers? Their EN54 cut-outs differ: LBC3099 210 mm, LC1-MFD and LC1-MFDS 190 mm, LC1-CMR 200 mm, LBC3086 196 mm, LC4-MFD 178 mm, LC4-CBB 162 mm, LC3-UM06E 170 mm. Ask us for the right model for your existing holes.
What do the power taps mean?
Each loudspeaker can be set to one of its power taps, for example 6 / 3 W. Choose a lower tap for small or quiet areas and a higher tap for large or noisy ones. Add up the taps of every loudspeaker on a line: the amplifier must deliver at least that total.
Many 6 W ceiling loudspeakers are tapped down to 3 W, 1.5 W or 0.75 W in the field; in smaller or low-noise areas 3 W is more than enough.
