Product Overview
The Tannoy CMS 603ICT LS is a 6-inch ICT point-source ceiling loudspeaker certified for life-safety signalling applications. Sold as a pair, it combines an Inductive Coupling Technology driver with multiple 70V and 100V transformer taps, serving 70-volt ceiling speaker systems and 16-ohm low-impedance zones alike. Its UL 1480 UUMW life-safety certification and UL 2043 plenum rating make it well suited to government, commercial, and house-of-worship installations where code compliance and reliability are critical.
Product Description
This ceiling speaker is built on Tannoy's third-generation Ceiling Monitor System (CMS 3.0) platform and uses a proprietary 6-inch ICT (Inductive Coupling Technology) point-source driver. The LS variant is UL 1480 UUMW certified for life-safety applications, making it suitable for non-DC-supervised emergency signalling systems where the others in the range are not. The inductively coupled high-frequency section removes a conventional crossover and contributes to the high long-term reliability ICT drivers offer in constant-usage installations, while delivering consistent broadband directivity and enhanced speech intelligibility. It ships with a fixed, acoustically enhanced zinc-plated steel back can and installs as a single integrated unit. A front-panel rotary switch selects 70V and 100V transformer taps or a 16-ohm direct setting for low-impedance amplifier channels, and the design is optimised for Lab Gruppen LUCIA amplifiers with up to eight CMS loudspeakers per channel. A self-aligning four-way clamp system, included C-ring, and ceiling tile rails speed deployment, while the removable magnetic grille can be custom painted. It carries a 10-year warranty and is engineered in the U.K. Browse the full Tannoy collection, or compare the standard ICT variant, the CMS 603ICT BM.
