Cooper Notification’s Wheelock Exceder low-profile, wall-mounted LED speakers and speaker strobes have a wide frequency response—300 to 8,000 Hz—which allows them to reproduce frequencies closer to the original sound. The LED is the strobe light source; it incorporates high-efficiency optics to minimize current draw. The speakers are dual voltage (25–70 vrms), have five field-selectable tap settings (1/8–2W), and four field-selectable candela settings (15, 30, 75 and 110 cd).
