Overview
What it is and how it fits the system.
The LSC-506 is an EN54-24 approved round 5-inch flush-mounted ceiling loudspeaker with capacitors, designed for voice alarm and fire detection systems. Rated at 6W on a 100V/70V line, it offers selectable power taps (6W/3W/1.5W/0.75W at 100V) and delivers 91 dB at 1W/1m and 88 dB at 6W/4m measured to EN54-24. Its 8-ohm driver and tapped impedances from 1.7K to 13K ohms suit flexible distributed voice-alarm layouts.
Technical overview
The LSC-506 is an EN54-24 approved round 5-inch flush-mounted ceiling loudspeaker with capacitors, designed for voice alarm and fire detection systems and offering full compliance with BS5839 Part 8. Selectable power taps on its 100V/70V line let installers set the output to suit distributed voice-alarm layouts, while the tapped impedances give flexibility across large, zoned systems.
Built-in protection means that damage to an individual loudspeaker does not result in a failure of the wider loudspeaker circuit; ceramic terminal blocks and a thermal fuse provide this integral safeguarding. The flush-mounted design, finished with a metal fire dome, makes the unit well suited to suspended ceilings. It is fitted using the mounting spring on the body, with the fire dome sliding into place over a flying-lead wiring arrangement.
Physical wiring and connection details, including the ceramic terminal blocks and flying leads, are covered in the installation manual rather than here; this datasheet is not intended for installation purposes. For physical connections, refer to the installation manual.
