Constructed with metal cabinet, the speaker is ideal for use in a voice alarm system. Can be surface- or flush- mounted to the wall. Either concealed in-wall wiring or exposed wiring can be used for speaker cable connection. The speaker structure of direct wall-mounting with screws prevents the speaker from falling easily even if an outward force is applied to. The input impedance can be easily changed by changing the tap position of the transformer. The built-in 16 cm double cone speaker unit delivers high quality sound. Two steatite screw terminal blocks (1 cable to 1 connection type) make bridge connection easier.

The speaker shall be a 16 cm (6") double cone-type speaker suitable for wall-mounting. Both wall and in-wall mounting shall be possible. Two steatite terminal blocks shall allow bridge connection. The speaker shall be EN 54-24 certified and compliant with BS 5839-8. The speaker shall include a transformer having multiple taps (0.8W, 1.5W, 3W, 6W at 100V line and 0.4W, 0.8W, 1.5W, 3W at 70V line) adjustable.
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) x 190 (H) x 87.2 (D) mm (12.2" x 7.48" x 3.43"), and a weight of 2.6 kg (5.73 lbs.).
The wall-mount speaker shall be a TOA model BS-680FC.
