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 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.
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.
