BS-678AB-EB

Cabinet Speaker

BS-678AB-EB

This wall mount speaker is specifically designed for voice alarm applications where AB wiring is required. The speaker structure permits direct wall mounting, with screws, which prevents the spaker from failing if an external force is applied. The input impedance can be easily altered by changing the tap position of the transformer.
The BS-678B-EB is certified to the European Standard EN54-24:2008. DoP number is 23-101.

Certified to EN54-24, ISO 7240-24 for use in voice alarm systems.
Compliant with BS-5839-8: 2023.
2 x 6W rated input (100 Vline) 6W, 3W, 1,5W.
Sensitivity SPL max SPL:
92 dB ( 2x 0.5W, 1 m) ( 100Hz - 10kHz, pink noise). 102 dB (2x 6W, 1 m) (100Hz - 10kHz, pink noise).
Sensitivity EN-54 max SPL EN-54:
80 dB (2x 0.5W, 4 m) (100Hz - 10kHz, pink noise). 90 dB (2x 6W. 4 m) (100Hz - 10kHz. pink noise).
Frequency response: 155Hz - 20kHz.

The A/B line wall mount box loudspeaker shall be equipped with two loudspeaker elements and two 100V transformers for complete separation of the A and B loudspeaker lines. It shall offer cost-saving installation of one speaker by an A/B wiring instead of installing two speakers. The housing shall be made of chipboard with steel plate net grille. Cable connection shall be via ceramic terminals with integrated thermal fuses.

Mounting of the speaker housing shall be possible separately when preparing the wiring for comfortable installing and connecting the speaker chassis later by spring catches.

The loudspeaker must be certified by a notified body in accordance with EN 54-24. The loudspeaker must meet the requirements of BS 5839-8:2013.
