CSS-15C-VA is a full-range, EN54-24 certified ceiling speaker consisting of a 127 mm (5 inch) full-range dual-cone driver, torsion-mounted into an included easy-install blind-mount metal fire dome. The speaker is designed to provide clear and intelligible sound for applications requiring EN54 certification and/or BS5839 compliance.A high temperature ceramic input connector with metal inserts secures bare wire terminations for +, -, and case ground connections, and an in-line thermal fuse protects the distributed speaker line from becoming shorted out when a fire or other issue affects any of the individual speakers. The backcan contains two wiring access holes with sealed diaphragm-type grommets to help physically protect the wire and helps to seal the system at the entrance point. The grommets can be replaced by installer-supplied 19 mm (3/4-inch) mount gland nut fittings if desired for additional seal capability or for additional strain relief capability.Suitable for a wide variety of projects, the CSS-15C-VA can be set for either 6 Watt, 3 Watt or 1.5 Watt operation on a 100V distributed speaker line.- Component: 127 mm (5 in) fullrange dual-cone loudspeaker- EN54-24 certified and compliant with BS5839-8 standard- 6W, 3W and 1.5W multi-tap transformer for use on 100V distributed speaker lines- Metal fire dome with easy blind-mount installation; clip-in torsion-mount speaker
