What does EN54-24 mean?
EN 54-24 is the European standard for loudspeakers in voice alarm (evacuation) systems. Certified models show EN54-24 in the banner at the top of their page; the others show Non-EN54 and suit commercial public address and music. For an evacuation system, use EN54-24 loudspeakers throughout.
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.
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.
