Audio signal device solid state 6/8VDC 2.8 Khz

Lumatone signals have a non-irritating harmonic tone that demands attention in both quiet environments as well as areas with high background noise. Models are available with pulsating audio and steady or pulsating visual/audio signals. Rugged solid state construction gives a rated life of 5,000 hours. No arcing, sparking or RF noise. Output of sound level can be varied by applied voltage (Min 80 dB at 1 foot with a voltage of 12Vdc is typical). Low power consumption makes them particularly suited for battery operated equipment and allows them to be turned on or off by low power integrated circuits, SCR...s and transistors. High impact polystyrene case.
