Wheelock Exceder LED3 High Fidelity Speaker Strobes


High Intelligibility for Emergency Communications

Designed for high fidelity sound output, Wheelock’s Exceder LED3 Speaker Strobes not only feature the widest frequency response range in the industry, but also are the first to utilize Light Emitting Diode (LED) as the light source. With a response range of 300 to 8000 Hz, the speaker strobes are able to reproduce frequencies closer to the original sound, providing leading intelligibility with crisp, clear voice messages, ideal for emergency communications and mass notification.

The Exceder LED3 speaker strobes feature an advanced power saving LED technology in a sleek, modern, enclosure that will provide high energy efficiency and an aesthetically pleasing low profile design that will blend with the building‘s interior décor. The LSPST3 appliances are ideal for indoor Mass Notification and Emergency Communication applications.

Eaton’s Exceder LED3 strobes meet the 20 millisecond light pulse duration requirements of the 2016 edition of NFPA 72. By meeting this latest requirement, xenon and LED devices can now be in the same field of view. With the Exceder LED3 line, Eaton now offers a full range of products with low and high candela settings ideal for both retrofits and new construction.
