Eaton’s Cooper Notification business has designed the Wheelock Exceder™ LED Speaker Strobes and Speakers for high fidelity sound output for indoor ceiling-mount applications. With the widest frequency response range (300 to 8000 Hz) in the industry, the Series LSPKC and LSPSTC feature leading intelligibility with crisp, clear voice messages and tone signaling, ideal for emergency communications, mass notification, voice evacuation and fire alarm. The Wheelock Exceder LED strobe models are the first notification appliances in the industry that utilize Light Emitting Diode (LED) as the light source—a breakthrough optical design, resulting in best-in-class efficiency that enables material and system cost savings, allowing for a greater number of appliances on the notification appliance circuit and fewer power supplies. Speaker strobe models feature a wide range of candela settings (15, 30, 75, 95 cd) on a single appliance. All switches to change settings can be set without the use of a tool and are located behind the appliance to prevent tampering.
