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.
Can this loudspeaker be used on a voice alarm line?
Ask us for the LBC1256/00 EVAC connection adapter: a 3-pole ceramic screw connector with a pre-mounted thermal fuse, installed in series with the loudspeaker's 100 V connection, so a loudspeaker damaged by fire does not take the line down. Sold in sets of 100. For certified evacuation systems, choose an EN54-24 model.
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.
Who supplies Bosch loudspeakers in Pakistan, and what warranty do I get?
Electronic Security Company (ESCO) is the only authorized distributor of Bosch, Dynacord and Electro-Voice in Pakistan, so every Bosch loudspeaker is genuine and comes with a 3-year warranty. Warranty is carry-in: bring the unit to an ESCO office and after inspection it is repaired or replaced as needed.
We supply, design and install public address and voice alarm systems, with offices and stock in Karachi, Lahore, Islamabad and Rawalpindi and dealers across Pakistan.
