Fully certified to EN54-24 for use in fire-rated commercial installations, the CS-6F provides a practical and compliant surface-mounting solution for corridors, stairwells, plant rooms, service areas and any other environment where a flush ceiling speaker cannot be installed. The powder-coated steel housing and grille provide robust, durable construction suitable for demanding commercial and industrial environments.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eFire-Safe Internal Construction\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eInside the CS-6F, the 6.5\" full-range driver is connected via fire-resistant cable to a ceramic terminal block and thermal fuse — ensuring the speaker assembly maintains its integrity and continues to function correctly in elevated temperature conditions during a fire event. The 100V line transformer provides tappings at 0.75W, 1.5W, 3W and 6W for flexible integration into large-scale distributed audio systems, and cable access is via gland knock-out holes for clean, professional installation wiring.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003ePractical Surface Mounting\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe CS-6F mounts via an internal removable cross-bar assembly that allows the speaker to be surface-mounted to ceilings or walls without the need for a recessed back box — providing a discreet, low-profile public address solution in spaces where conventional recessed installation is not an option.
