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 is the difference between Entry, Mid and Performance Level?
- Entry Level: speech and alarm tones in public address and voice alarm; cost-efficient, nothing more, nothing less.
- Mid Level: high-quality speech plus background music, metal fire dome, more installation features. Mid Level horns add long throw and aluminium for demanding sites.
- Performance Level: evacuation and high-quality music in one housing.
It is about the job, not the price: if you only need alarm tones in an emergency, an Entry Level loudspeaker is reliable and perfectly fine. Pick Mid or Performance for background music, easier installation or more robust materials. Horns: Entry, Mid, Performance.
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.
