Wheelock Exceder LED High Fidelity Speaker Strobes


High Intelligibility for Emergency Communications

Designed for high fidelity sound output, Wheelock’s Exceder LED 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 patented LED technology delivers industry's lowest current draw, allowing for energy savings of 52%. This breakthrough optical design results in best-in-class efficiency, allowing for a greater number of appliances on the notification appliance circuit and requiring 20 percent fewer power supplies. 

The Exceder LED Speaker Strobes for indoor wall- and ceiling-mount applications also feature one of the industry’s smallest footprints and a sleek, modern, low-profile design.  Installers will benefit from five field-selectable tap settings (1/8 to 2 watts), four field-selectable candela settings and convenient mounting options for both new and retrofit construction.
