Federal Signal’s Visalert® is a three dimensional, triangular warning light designed to be mated with Federal Signal’s Model 350 Vibratone® horn and the Model 50GC SelecTone® speaker/amplifier. The Visalert can also be used as a stand alone device. Visalert is available in five lens colors: Amber, Blue, Clear, Green and Red. 

Knockouts on the 50GC and 350 audible devices (sold separately) ensure easy installation. The units can be either independently or simultaneously wired with the audible device. The Visalert uses a linear strobe tube and all the circuitry is contained within the lens.

Visalert units are recommended for use in industrial applications and situations where effective visual warning is needed. The Visalert can be surface mounted on the Model 350 or Model 50GC speaker/amplifier. 

Federal Signal’s Visalert strobe light is an affordable, low-maintenance strobe light in a compact size that is perfect for control panel applications.
