Ceiling Mount Firedome Speaker
PC-1860BS-C
The PC-1860BS-C ceiling mount speaker is certified to EN 54-24 and compliant with BS 5839‑8:2008. It is designed for use in announcement and background music systems. Its unobtrusive design harmonizes with the architecture and décor of various installation environments. The speaker employs a spring catch mounting mechanism for secure ceiling installation. It is equipped with a fire dome to prevent the spread of fire through the ceiling in an emergency, and includes a 1 µF bipolar blocking capacitor that enables DC monitoring of the speaker line.

The loudspeaker shall be of in-ceiling type design and shall consist of two parts, comprising of an inner mesh grille and chassis with an integral loudspeaker with no visible fixings and a discreet outer bezel of only 5 mm. The second part shall be a steel constructed fire dome for the prevention of smoke or fire spreading through ceiling voids in an emergency situation.
Installation shall be via a separate spring catch latching mechanism allowing it to be mounted in a ceiling with a thickness of between 5 – 25 mm (0.2" – 0.98"). A template shall be provided to assist in cutting mounting holes. The ceiling mount loudspeaker shall include a DC blocking capacitor to enable DC line monitoring of speaker circuits and a thermal fuse.
The loudspeaker shall incorporate a single 12 cm (5”) full range cone-type transducer with a smooth frequency response of 170 Hz to 20 kHz with a wide-angle dispersion. The loudspeaker shall produce a Sound Pressure Level (SPL) of 94 dB (measured between 500 Hz – 5 kHz of pink noise) on axis at 1 meter with a power input of 1 watt and 80 dB (measured between 100Hz – 10kHz of pink noise) on axis at 4 meters with a power input of 1 watt. The loudspeaker shall be capable of producing 6 watts (for 100 V Line) and 3 watts (for 70 V Line) of power.
The loudspeaker shall be fitted with a factory mounted transformer with easy selectable power tappings of 6 W, 3 W, 1.5 W and 0.8 W when using 100 V Line and 3 W, 1.5 W, 0.8 W and 0.4 W when using 70 V Line. Connection shall be made possible via two steatite three pole connectors capable of handling solid cable: 0.8 – 6 mm² (AWG 18 – 10).
The ceiling mount loudspeaker shall incorporate suitable anchoring points, as an additional precautionary measure, allowing an attachment of a safety wire to avoid displacement. The dimensions shall be Ø180 × 100 mm (d) (7.09" x 3.94") weighing 1.1 kg (2.43 lb.) The finish of the loudspeaker shall be: Baffle: steel plate, white (RAL 9016 equivalent). Grille: Steel net, white (RAL 9016 equivalent). Fire dome: steel plate painted black.
The ceiling mount loudspeaker shall be certified according to the following standards: European Standard EN 54-24: 2008, International Standard ISO 7240-24: 2010 and shall comply with British Standard BS-5839-8: 2008.
