BS-680FCWall Mount Speaker System

DESCRIPTION

FEATURES

The BS-680FC speaker has a strong, all-metal body, and are ideally suited for voice alarm system applications. 16cm (6") double cone speaker unit ensures high-quality sound. The speaker can be quickly and easily installed in either a horizontal or a vertical orientation. Either concealed in-wall wiring or exposed wiring can be used for speaker cable connection. BS-680FC is EN 54-24* certified and is therefore legalized for a use in conjunction with fire detection systems. It is also in compliance with BS 5839 part 8. Two steatite screw terminal blocks (1 cable to 1 connection type) allow bridge connection. The selectable input impedance can be easily adjusted by changing the top position of the unit’s transformer. Both wall and in-wall mounting are possible. The innovative structural design is based on the Golden Ratio (1: 1.618), and also permits direct wall installation with screws, making the speaker unit resistant to falling even if outward force is applied to it.*EN 54-24: Loudspeaker for voice alarm systems for fire detection and fire alarm systems.

The sensitivity at 1W input measured at a distance of 1m shall be 94 dB (500 Hz to 5k Hz, pink noise). The speaker shall have a frequency response of 150 to 20k Hz (-20dB).

The specifications based on EN 54-24 measurement conditions are follows:The sensitivity with 1W input shall be 74 dB at a distance of 4m and 89 dB at a distance of 1m converted based on EN 54-24 (100 Hz to 10k Hz, pink noise).

The maximum sound pressure level with 6W input shall be 84 dB at a distance of 4m and 96 dB at a distance of 1m converted based on EN 54-24 (100 Hz to 10k Hz, pink noise). The coverage angle (-6 dB) shall be: 180 degrees (horizontal and vertical) at 500Hz, 140 degrees (horizontal and vertical) at 1k Hz, 120 degrees (horizontal)/110 degrees (vertical) at 2k Hz and 100 degrees (horizontal)/80 degrees (vertical) at 4k Hz. The environmental type according to EN 54-24 shall be A (indoor application).

The speaker baffle and cabinet shall be constructed of steel plate. The grille shall be surface-treated steel plate net. The speaker shall be available in off-white color. The unit shall have dimensions of 310 (W) × 190 (H) × 87.2 (D) mm (12.2" × 7.48" × 3.43"), and a weight of 2.6 kg (5.73 lb).

The wall-mount speaker shall be a TOA model BS-680FC.
